Seiko Prospex Kinetic GMT - SUN023 a.k.a. Kinetic Tuna Review & How to setup & use

[@monzer3750]

Seriously this guy is a legend when it comes to watch review . he absolutely answered all my questions and nailed every aspect of the watch . Great reviews dude keep it up . love your channel . for god sake just by mentioning the lume is not radio active is just incredibly useful coz if I want to buy this watch and ship to my country if its radio active it wont get through customs . pretty generous amount of information just amazing thanks .

[@WatchGeek]

Thanks!!! I'm glad you liked it and found it useful 😊

[@stephenward3468]

I love my SUN 021.It is so accurate and the second hand hits the hour markers spot on.The bezel also hits the markers.SEIKO are fantastic their technology and design really shows.

[@ahalfkorean]

I've had the SUN023, SUN065, and the SUN043 for about 6 years now, and I'm just now seeing your review. Great review! I watched the whole video, and it's given me a renewed appreciation for the trio. The battery level drops pretty quick on all three, so I'll need to look into getting some service.

[@Gavinconaghty]

Loved this review! I have had a kinetic watch for 12+ years and love it. I had the capacitor replaced about 2 years ago for like $50. Super accurate and only needs a new battery/capacitor every 10 years.

[@alt0v14]

Maybe I am that special kind of person, but watching your videos is such a pleasure, and I never needed to go through time codes :)

[@eriklind5174]

I picked up the PADI version as my first kinetic and absolutely love it

[@matthewchen1006]

Recently I got a Seiko Kinetic GMT. But for days I couldn't figure it out how the GMT works, cause I expect that the two hands will move simultaneously, but it wasn't, so I thought maybe mine is broken or something wrong. And thank god I watched your video and now I figure it out how this work, thank you really!

[@R3aperCr3W]

I am that special kind of person and I watch it till the end...

[@driver3025]

I just purchased the PADI version today. The watch is just spectacular. The Lyme is incredibly thick. It’s a beautifully finished timepiece.

[@WatchGeek]

I wish seiko made a smaller version

[@driver3025]

Watch Geek I have a big frame. It wears nice. Much TALLER than a turtle or skx but somehow fits the wrist comfortably.

[@22jeepmojave75]

I’ve sun065 and it’s the best daily watch ever. Durability and accuracy is unbeatable

[@jhsanta]

Thanks for the review. I have to admit that every time I want to buy a watch or learn more about it I always look for your reviews. Just ordered the PADI version.

[@WatchGeek]

Thanks and congrats on a great piece

[@marvinsimpson3255]

Great review. Tried this on at a mall jewelry store and liked it a lot more than I thought I would. It prompted me to watch this (excellent) review. I have 6.5 inch wrists myself and completely agree with your assessment on the size. Yes, it's bigger than I prefer, but with the way its shaped it is reasonable and was quite comfortable. Thanks for all the information - you filled in all the blanks I was looking for.

[@WatchGeek]

I'm glad I could help 😊

[@HRM.H]

I've just bought this watch for only 230 euro! I'm stocked. The bezel and crystal were in pristine condition. Bought a new shroud for it already !

[@WatchGeek]

Thats a great price, congrats

[@barrygrimmett6394]

Watched your review, bought a PADI and this Tuna. Awesome watches.

[@alexandruignat8623]

I own this watch. It's a wonderful timepiece. And I couldn't agree more with your review. Thanks.

[@christopheromeara986]

Nice review. I ordered a SUN065. I plan on when I’m not wearing it, to put it in the winder. That should keep the Charge up.

[@Tdww]

Doesn't work...

[@edyue1]

excellent comprehensive review, your elocution and humor made the 20 minutes very entertaining. Seiko should give you a complimentary watch :)

[@WatchGeek]

+Ed Yue thanks for the kind words and I hope your words come true 😜

[@danijuggernaut]

Great review, i got the SUN019, lovely piece. Thanks for the explenation to adjust the GMT. Anyway i can´t understand the GMT on a diver watch, but you have to understand that smaller hour hands and a big minute hand has sense on diver watches. On minimal specification requieremenst described on ISO 6425, says clearly that hour and minute hands have to be diferentied. Super explenation about the Kinetic system, magnetic levitation bearing and 100´000 rpm.....this is crazy.

[@ramonalbertotamayoisla2592]

Excellent, I regret I did not watch this vid bcz this watch is so big for me. At last I ve found someone besides me who appreciate Kinetic tech.

[@bonzerrrrr]

Excellent video! Picked up a “Showcase display model” from an authorized dealer at a nice discount. The Kinetic Tuna is the coolest of the Tunas‼️ 💯,000 spins a minute 💨 😎

[@ralphtaylor9968]

Just watched you video with your usual fantastic detailed and practical advice, thank you. This watch is going on my Christmas list to Santa, for sure 😊

[@WatchGeek]

Thanks and congrats 😊

[@wargamingrefugee9065]

Great review! And thanks for sharing your knowledge concerning the color coding of hands with watch function. (I'm old, own a couple of chronographs, and never caught on to the correlation of function with hand color. It's always good to learn.)

[@WatchGeek]

+WarGamingRefugee I'm glad you found it fun and useful :) Thanks for watching

[@Tdww]

I didn't understand the booklet I got with the Seiko Sun065, your video helped me!

[@smugeyed]

Nice review. One thing, flat crystals do not cut down reflections. They actually "flash" much brighter than a domed crystal. Not good when you are being followed by a Barracuda!

[@TRPD]

The texture of the dial is an hommage to the seiko "space walk" watch.

[@edvargas72]

Thanks to you I get to love this seiko even more,, I was so impress with this review that I own 2 now....

[@WatchGeek]

Haha that's nice to hear, as to being valuable in the future that is very hard to say

[@monzer3750]

hello , I'm about to buy my first kenetic watch more like my first luxury watch I'd say . Would you recommend it ? I have my doubts about the battery and charge .

[@MARTINespartano1]

My Man, you explain very well! Thanks for the info. Remarkable watch

[@rolandbjr.1761]

Great review.! What is the bezel insert size on this?

[@janreeves5443]

I may be solving my own "problem" just by wearing my new SUN023. First - it keeps PERFECT time. Second - it seems to be very slowly increasing its power charge. It seems to have settled in the 20 second power indication. I can get the full 30 seconds with some brief aggressive shaking/winding. I find myself wanting to like this very unique design.

[@WatchGeek]

+Jan Reeves just keep wearing it 👍

[@pag1905]

excellent walkthrough, smooth presentation!! bravoooo!!!

[@WatchGeek]

Thanks 😁

[@paullowe2906]

Great video and watch ⌚ 👌

[@harvardford8752]

Man I’ve only recently found about you and I freakin love your videos I binge watched so much videos LMAO GLAD I SUBSCRIBED

[@WatchGeek]

+Harvard Ford I'm glad you enjoy, and thanks for the views and subscription, I appreciate it

[@taymot2131]

GREAT! The review - and the watch. Thanks very much.

[@omegacontrol9889]

Great review, thank you. But I still have no understanding of how to understand GMT time??

[@danijuggernaut]

Very simply, the worl has 24 meridians (1 hour each) but your watch dial has only 12. That means that every 2.5 minutes marc on your dial correspond to one hour. 12 o´clock postion is Mmidnight, 3 o´clock position is 6 in the morning, 6 o´clock position is noon, 9 o´clock position is 6 afternoon and again 12 o´clock position is midnight.

[@maverickwatchreviews]

I just wanted to let you know that I uploaded a brief review of the GA-100L2A today and then told my subscribers that if they wanted a more thorough review of all of the watch's features to check out your channel :)

[@WatchGeek]

+MAVERICK WATCH REVIEWS oh wow, thanks :) It's nice to know a big channel knows about me.

[@whatsonthewrist]

It's on the larger size for me, but I like the color combo. The quartz accuracy seems to allow the seconds hand to land flush on the minute markers. Congrats on your first watch provided by the jeweler, I like the trust involved. Nice comprehensive review as usual.

[@WatchGeek]

+whatsonthewrist yes it is VERY LARGE and commands a lot of wrist presence, way to much for me as well! I hope the collaboration continues :)

[@whatsonthewrist]

Me, too. I mean you're doing a great job for them, so it should! Keep it up!

[@WatchGeek]

+whatsonthewrist thanks :)

[@greekall]

kinetic's are beasts.in terms of accuracy cause basically are quartz watches.btw i have one of 1st gen seiko kinetic model shf045p 150 m. wich is not a trully divers but trust me i have changed 1 and only 1 time the capacitor after about 25 years.its a rare timepiece ,daring to say that is almost vintage..and to find one of those in a working condition,good shape,and ready to wear and go,its damn hard as h@ll.24 years to my hand,never let me out.btw these watches are made to be worn,never let em do a full discharge.sorry but i cant post a photo of my rare kinetic,but its ok.anyone can google it.great rewiew as always.👍👍👍👍👍

[@WatchGeek]

That's a great story and you're right, wearing them constantly is the best way of making them last

[@BarakTheWonderer]

Nice job. Very thorough. Thank you.

[@poopongmcplop3635]

Thanks for the video, I found the part about the Russian watch very interesting too. Quick point to make tho: Underwater, the FIRST colour to go is RED, then ORANGE because they have the longest wavelengths and thus the least energy. So your explanation for the colour choice is inaccurate. While the colour goes, the face will look light greyish so plenty of contrast when looking at the dial. Imho dark outlines on the minute hand with luminous paint filling their shape in against a watch face in orange would work. This watch does the reverse, with organge minute hand on a dark face .. should also work but you wont see that orange below 5-7 meters and in less depth than 5 meters you aren´t diving ;).

[@liadijkstra9614]

There is also a Black with gold special edition sun045. I know because i have one..

[@WatchGeek]

+Lia Dijkstra thanks for the info, was not aware of that one 👍

[@pandaofspadez09]

Is it normal for the gmt hand to mover slower than the hour hand ? For example. I put my local time 12pm est. I set the gmt to 9am pacific time. I leave it for a couple hours. My local time will be 2pm. My gmt hand will still be around 9ish pacific. Is this normal? Or am I reading it wrong ? 🤔 help me understand. Thanks -a person who is still trying to understand how a gmt works

[@ahalfkorean]

The GMT hand will run slower as it's using the 24-hr track for the time instead of the 12-hr track of the main time.

[@Wildmountainsafaris]

This was such an interesting and informative video - a shame this isn’t produced in a smaller size - but it is a pro diver and meant to be worn diving and needs to be visible - I see Seiko issues these to their PADI reps and pro divers

[@weedXD38]

Glad to see a vid from you of course ,excellent review as usual thank you for sharing!!! :-) :-)

[@WatchGeek]

+weedXD38 thank you for taking the time to comment as usual, I appreciate it :)

[@janreeves5443]

Great review. When you demonstrated the power reserve button you unscrewed it before you pushed it. Does the button work only when unscrewed? I assume you need to screw it back down after you use it to preserve the integrity of the watch.

[@WatchGeek]

+Jan Reeves yup, you're right on both of these, while screwed in you cannot press it. And yes you have to screw it back in to guarantee water resistance, although it is still water resistant, in the case of an accidental button press you will have trouble 😊

[@janreeves5443]

Thanks. I just got a new SUN023 two days ago. Both the crown and the power button came new in the box "unscrewed." The crown operates fine but the power button will not screw down so the button cycles to give you the power level every time anything touches the button. It's going back.

[@WatchGeek]

+Jan Reeves it will screw down it's just different than the crown. Try just screwing it without pressing like you do with the crown, at least that is how mine works, I thought at first it was weird too

[@janreeves5443]

I've tried everything and it just won't turn - seems to be locked in the "unscrewed" position. Fortunately I bought it from AmazonPrime - it's on its way back with a new replacement being delivered to me tomorrow. Hard to beat Amazon for excellent customer service.

[@WatchGeek]

+Jan Reeves glad to hear you are covered, and I'm sure the replacement will be fine 👍

[@tagman1]

I am selling this watch. I've had it since brand new and it never did well with me. The crown would dig and hurt my wrist. They should've put the crown at 4:00 like their other large dive models. But it's very very cool looking. The crown was the downfall.

[@caye74]

I love how those kinetic GMTs look, but sadly way to heavy/big for me. Excellent for left hand biceps though :D

[@WatchGeek]

+Goran Belaj haha, true 😂

[@efreutel]

Superb review. Thank you!

[@bossoli60]

Stil I prefer my SUN019p1 but Kinetic tuna are great as your video …and the lume…😮

[@supmojo]

Have the same exact watch.

[@potterj09]

Damnit I just got a really nice silver on black solar tuna, now I see this video. The buckle looks abit nicer too. Luckily I got a viking wrist this watch would be brilliant. On my ebay watchlist now lol

[@SuperHARLEY27]

Great review!! decision point was made with this video on purchasing watch! If I was a betting man I would say your from Quebec?! I am from N.B originally now living in Saskatchewan! thanks for great review!

[@WatchGeek]

+SuperHARLEY27 haha I'm glad you liked it and congrats on the future watch 👍 I am from Croatia, Europe 😊

[@747nemesis]

Have this watch. It's build quality and feel is amazing. Has anyone upgraded to a domed sapphire crystal? Any leads where I can find it

[@Tdww]

It has sapphire!

[@swabby429]

I own a Kinetic and hate it. The battery still takes a charge but it only lasts a few days. So, I keep it near my computer so I can pick it up and shake it. It usually takes ten minutes to charge up that way. When I wear the watch, it doesn't charge much, so I end up shaking it again. I wanted to have the watch serviced, but it cost nearly $100 to do so. This cost is much higher than it is worth. I plan on giving the watch to a collector friend then I'll buy a Seiko solar or a Citizen Eco Drive. Solar is a much more sensible, less irritating technology.

[@Bobsbargainbasement]

Great video as usual! I like the tuna but not 100% sold on Kinetic .

[@WatchGeek]

+Robert Sanchez thanks :) like I said it reminds me of the Rotary engine, and I like it BECAUSE it's different. A friend of mine dug up a 13 year old kinetic from a tool shack a couple of weeks ago, and I gave it a shake and it started ticking, it's been working since then, no problem, so they are reliable if not discharged often

[@Bobsbargainbasement]

Watch Geek I do love the Rotary I'm a big Mazda fan as I worked for Mazda dealerships for 17 yrs as a sales manager And I drive a Mazda 3 , 2.3l 5 spd great little car though a bit tight for my size ! Lol

[@WatchGeek]

+Robert Sanchez really? I drive a Mazda as well, a 6. 2010 Euro spec 2.0, a very agile car and fun in the corners, NOT something one would expect from a family saloon :)

[@Bobsbargainbasement]

Watch Geek That's cool, mine is a bit modified with Eibach springs , Mazda 6 rims on low profile bf Goodrich Tires, air intake and exhaust. Handles great like a go kart. It's kind of funny to see a 66 year old man driving A pocket rocket! Lol

[@WatchGeek]

+Robert Sanchez haha that's cool :)

[@christophertaylor9230]

Your sense of humour is excellent! 😂😂 Interesting watch, the GMT hand will confuse me! How is Capy?

[@WatchGeek]

+Christopher Taylor thanks and I'm glad you enjoy it! Capy is still kicking it, going swimming and walking, although he is a bit leaner these days, just like old people get skinnier with years

[@lulul]

thank you for this.. it's not useful info for me at all but still i enjoyed all the little tangential information so much that i felt compelled to thank you..

[@WatchGeek]

Thanks, and I always try to share some general watch knowledge that I have stored in my mind with each video, since everywhere else it is mostly useless :)

[@kennethjohnson1158]

Excellent review!

[@WatchGeek]

Thanks

[@ihodeputa2905]

Very nice review👍🏻

[@WatchGeek]

Thanks 😊

[@JeffreyMcMahon]

I love that watch. I wish it weren't kinetic. Too stressful for me.

[@WatchGeek]

+Jeffrey McMahon 😂😂😂 so true!!!

[@rangermedic8564]

Watch Geek Can you educate me, I being serious, What is stressful about Kinetic energy. What is it that I dont know. I just received this watch TODAY. Dr. Adams

[@WatchGeek]

Any rechargable battery will have its life shortened by a huge margin when you discharge it often with a high DOD (Depth Of Discharge) meaning the more often you allow it to drop to very low levels the lower life expectancy of the battery is. Because of this you want to keep your battery topped up as much as possible, which is not a problem with Kinetic IF it is your only watch and you wear it every day, BUT for people who have a watch collection it becomes a problem as they HAVE to put that watch in rotation with other watches to keep it on high charge. The same goes for solar watches, but with them you don't have to wear them to keep them charged, you just avoid storing them in dark places like drawers, which makes them A LOT easier to maintain. But, like I said, if Kinetic is your only watch these is no stress at all 😁👍

[@alphasportstv]

Great review thanks

[@PickinNgrinin]

Great review

[@WatchGeek]

Thanks 😊

[@janreeves5443]

Just got my new SUN023 and I am concerned about the watche's ability to hold a charge. When it came it had "five seconds" on the meter. After shaking it vigorously and wearing it for a few days I was able to get it up to 20 seconds and even saw the full 30 second reading but not for long. Now it quickly settles back down to 10 seconds. If I shake it for a few minutes it jumps back up to 20 seconds. Am I being paranoid or is this reason for concern? This is my first Kinetic experience

[@TheBlackDog73]

Jan Reeves 20 seconds prob 4 months reserve

[@BeNoRed]

I initially had that problem with my SUN019 and it took 15 minutes of shaking to get a month of reserve. That continued for awhile but now, for some reason, it only takes 5 minutes every other week to keep it fully charged. Might be temperature because it's now winter. Not sure but mine, at least, got better. Great watch

[@NeuroBoy314]

Beautiful watch, but one kinetic on my collection is enough! 😲😲😲 I really turns in a headache to keep it charged!

[@angeldc54]

I have 4 Seiko kinetics. Great concept but in real life they're a pain in the ass.

[@R3aperCr3W]

After watching this video I wonder why others Seiko watch videos only last 2 minutes others even as short as 94 seconds like seriously .

[@m44t59]

👍

[@swabby429]

This is a beautiful watch, but I already have one Seiko Kinetic and one Kinetic is enough.

[@WatchGeek]

+J Johnson I agree, Kinetics are a chore to maintain, so a couple can become a burden 😄

[@monzer3750]

I'm about to buy my first kenetic watch more like my first luxury watch I'd say would you recommend it ? I have my doubts about the battery and charge .

[@WatchGeek]

Anyone you like the look of will be fine. If it's going to be your only watch that you will wear every day you don't have to worry about the charge and battery, but if it's going to have one of many you wear or a watch for special occasions that you wear sometimes, go with solar or regular battery operated as the Kinetic will die in you and fail

[@jegesbubu]

good stuff!

[@WatchGeek]

+jegesbubu thanks :)

[@miked2662]

I'm that special person and instantly feel like an asshat -_-

[@WatchGeek]

+Larry Duncan haha I didn't mean anything bad, as I am that kind of person as well, but others might find us weird for watching and actually enjoying long videos about watches, or even reading for hours about them, I know my wife thinks I am crazy 😄

[@miked2662]

Watch Geek haha it's all good man, I'm fairly certain my girlfriend thinks the same but doesn't say anything of it. I like the Mazda analogy, My last four cars have been Mazda's, I currently drive an NB2 Miata, your description is why I always go back and why I've had three Miatas! They do things others won't.

[@WatchGeek]

+Larry Duncan glad to see another Mazda driver! I drive a 2010 Euro spec Mazda 6, a car I fell I love with on a test drive after the first corner! I drove the 3rd generation for a couple of days and it was AWESOME

[@reymaduro9258]

Great review, I just subscribed! I have three of these "Kinetic Tuna's" and all three have loud bezels, just saying. Also, I purchased a "Kinetic Winder": kzbin.info/www/bejne/gYDWgGh-baesaZY I hope it works.

[@WatchGeek]

+Rey Maduro that's funny because this is one of the quieter bezels I tried :) The watch is a head turner 😍 I just wish I had a bigger wrist! Thanks for the subscription 👍

[@johncalberg1573]

Its a beautiful watch. So i bought one 2 months ago. Now its dead and in for service because I didnt "walk the dog"

[@kdochce-vidi8540]

quartz xú

[@sashachip]

Seiko needs to just be done with the Kinetic movement. It’s pointless.

[@ericfreutel8240]

Great review. Terrific watch.
