Everything You Need to Know About Seiko GMT - In-depth Review of Seiko SSK series and 4R34 Movement

[@DIYWatchClub]

Our first ever watch review! It's super exciting to try this new form of content, and I spend a (exceedingly) lot of time to come up with this review. I'd love to hear your thoughts on this review, whether it works for you or not, and how I can improve on this type of content. Fire away down below!😉

[@deanwoods9294]

Looking forward to you guys bringing out a new GMT kit! Great review...it's nice to see you pull a watch apart during a review and get more into the technical side of things as opposed to just focussing on fit and finish like most youtubers

[@DIYWatchClub]

That's exactly what we try to provide the the community. Real in-depth review. Btw we DO have a GMT kit now, go check it out! shop.diywatch.club/collections/special/products/new-arrival-diy-watchmaking-kit-nh34-gmt-dive-watch-with-extra-strap-dwc-d03

[@Nadinetherescuehound]

My wife just bought me this watch. My first true automatic legit watch. I'm tickled to death. Dial is stunning and the second hand sweep against that dial is very beautiful. It wears smaller than it lists on the wrist too. Skinny wrists are good cause L2L is shorter than most it seems. Wears like a 40. Fabulous watch. Recommend to anyone looking for a watch where you can invest your hard earned coin, into a do it all type durable case with movement that's going to be attractive to collectors in the future. First model year on these watches with this movement might be a wise investment, just for collection, let alone a beautiful watch.

[@DIYWatchClub]

Fascinating to hear your beautiful review! Glad you're enjoying it!

[@1968jpy]

I’ve had my SSK003J1 now a little over a month now . I’m seriously loving this watch a lot . The only thing I changed was I added a Marine Master clasp to the stock bracelet. Definitely gives the bracelet experience a serious improvement. I own the SKX009 and this new GMT is giving my SKX a run for it’s money 💰. Receiving this watch is the most I’ve been excited for a watch to arrive in a long time. The SSK003J1 blueberry did not disappoint, extremely happy and pleased with this watch 😄👍🏻💯

[@DIYWatchClub]

That's a nice clasp upgrade!

[@1968jpy]

@@DIYWatchClub thanks. About two years ago I did the same with my SBDC033 Blumo and when I realized the bracelet tapered to 18 mm I ordered one right away. I just wish Seiko made a 20 mm clasp like this as well. The Marine Master clasp is one of the best adjustable clasps made for a watch .

[@jamesdaly1111]

I bought the Scattered Waves NATO strap from the Seiko Boutique and I love the way it looks

[@bullitt8986]

@@1968jpycan you send a picture of it? Just got this watch and it’s beautiful. Only complaint which it’s still totally fine. Is the clasp.

[@juanzamarripa3778]

How much time does this movement lose or gain in about a months time? And how often do you readjust the time? I only ask because my experience with automatics is that they very inaccurate time keepers.

[@edscoble]

Subscribed because you’re the only one whom made watch contents accessible by having closed captioning (unlike other like Teddy, W&W, etc.)

Yes, I want the Seiko GMT for traveling overseas. The GMT feature will allow me to tell home time without having to pull out my cellphone. Excellent video my friend!

[@DIYWatchClub]

Good choice!

[@sjcst35]

I travel international for a living(Pilot). Recommend leaving the time set to your home time zone if it’s a short trip. Then you can use the rotating bezel for local time in conjunction with the gmt hand.

[@SpiritualEagle]

Got this one and arrived a week ago. What a beautiful timepiece that has been added to my collection!

[@waynepersence2192]

I bought this watch recently and I think it’s great so far 🎉

[@GarNelson1]

I'm personally more excited about the NH34 movement being available than the complete watch SSK003. The only part missing is an easy way to expand the center hole in aftermarket NH35/36 watch dials.

[@alanmckinnon6791]

You use a broach or a reamer, a standard jewellery maker tool. You'd likely need to clamp the dial between two supports (2 large acrylic washer-shaped object?) to prevent the dial flexing and chipping the paint on the dial

[@Frankiewizard]

Absolutely amazing, keep the videos coming.

[@DIYWatchClub]

Thank you for the kind comment, that means a lot to me!

[@MWH_Watch_mods]

Great stuff! BUT, if you want to change the dial, you have to ensure the central hole is slightly bigger, due to the central stem being slightly bigger. (I just found out the hard way 😱😥) No worries, I’ll use a diamond file to slightly enlarge my Marinemaster dial.

[@natraj5689]

I bought this watch & waited for someone to review it and here I am, thanks mate!

[@paulkett8414]

Great review I've owned mine for a month now and really pleased with it! I've noticed it loses 5-10 second's a day but I've researched that this is normal for this type of movement? Would a service pick this up and adjust the speed at all???

[@TeddyBoy7796]

Great vid, I’m very interested in getting one and would love to know the other ways to utilise the GMT as I have no use for it for different time zones and always use the standard 60 minute dive bezel for measuring time elapsed on my SKX and 5KX so can’t wait to see the future vid, thanks.

[@DIYWatchClub]

I'm making a video on exactly that, stay tuned!

[@masteranakin8827]

Most people who are into watches know how to use a normal watch as a compass, but with a GMT it is even easier. With the small hour hand pointed at the Sun the GMT hand points roughly North, when in the northern hemisphere, when in the southern hemisphere it points south.

[@discountmorty213]

I been winding 4r34 for like 80 turns thinking how come it can wind for so long then I read that the movement cannot be overwind as in it got a overwind protection?

[@brianmsahin]

Very nice watch and very nice video. Just subscribed !I'm sure you know by now that the bezel insert is hardlex glass, not acrylic. I just want to ask. Did you find out if we can fit an NH34 movement into a Seiko 5 SRPD model ? Maybe you made a video on it , but I can't find it !

[@shawnwilliams4187]

I would like to know how come when I don’t wear my watch for a couple of days it stops running, is it ran by light I’m pretty sure it has a battery

[@shoesters6298]

Got mine in orange love it

[@Natosap84]

I have two questions: 1. How can I tell if my watch is fully wound when I wind it with the crown? 2. How many turns of the automatic winding rotor are needed to fully wind the watch? Thank you!

[@Natosap84]

Answering my own questions: 1. At first, the crown turns easily with almost no resistance. When the mainspring is fully wound, you can feel the crown moving in small jerks, and the resistance increases. If you wind the watch after 24 hours, it usually takes about 30 turns of the crown. 2. Around 650.

[@marcsmith-wl9pw]

I’m getting the 001 can’t wait.

[@Sonny-y7s]

Hi, can this watch be added a screw down crown?

[@Floodbait_117]

I got one of your kits for xmas and love it its like +/- 5 sec compared to my citizen fugu at like 15 +/-

[@shakeswigglez999]

I just purchased A Pagani Design 1662 with the NH34 movement in the Batman model for $100. Not as nice quality as this watch but it's a good watch for someone on a budget like myself.

[@TerminusVox]

While I can't afford a Seiko movement in a Seiko case I can afford a Seiko movement in another brand's case. I'm hoping these movements make it to the wholesale market sooner than later!

I love my SSK but it looses 24seconds every day. Which makes me sad. I wonder if I can find a Watchmaker to regulate it better. The Timeloss is very consistent though…

Masalah apa yang sering terjadi pada seiko gmt ???? Tolong beri tahu saya

[@aviator_bryan]

The Seiko is a nice looking watch. However, the San Martin SN015 GMT has higher specs, and around $100 + dollars less in cost. It has a 4hz (ETA clone) movement, sapphire crystal, screw down crown, 200M water resistance, better overall finish of case and jubilee bracelet (with screws not pins), bi-direction bezel with click, anti reflective coating, super bright lume on dial AND bezel, signed crown... I feel like there is more, but you get the idea.

[@richardharris2042]

I doubt the lack of screw down crown has anything to do with the water rating. The crown/stem design is exactly the same as SKX or Marinemaster, ie, the gasket is on the stem not in the crown head. I would presume the lower water resistance is because of the see through case back.

[@ayayoutuber]

plenty of 300 and 200 m see through case back watches... it's not just the back.

[@SrJonAnthony]

Its not about the gasket, its about holding the crown down and tight. If its out and loose then water gets in no matter the gasket or oring. This a sport/diver not a iso diver. Iso must have screw downs, etc.

[@richardharris2042]

@@SrJonAnthony The gasket on the stem has no idea whether the crown is screwed down or not. Threads on a metal crown provide zero extra water resistance.

[@SrJonAnthony]

@richardharris2042 threads when tightened squeeze the gasket. What are we debating here? When the water pressure exceeds that of the "unsqueezed" gasket. Thats also why oiling the gaskets is important( repelling water). If your crown is torn off or bent while fully extended then water is getting in. Screwing it down prevents this. We all understand this right?

[@richardharris2042]

@@SrJonAnthony the gasket is on the stem not in the crown, it is not squeezed, it's not a Rolex or Vostok

[@jonatansterling397]

How about the accuracy of this watch ?

[@DIYWatchClub]

Seiko claims a factory standard of +45 to -35s/day. Our sample comes in at +6s/d. But if you want to improve it yourself, you can always regulate it yourself: kzbin.info/www/bejne/rKvCYqWeoZafrLs

[@soundscaperecordings1111]

Miss aligned chapter ring galore. I've bought 3 all the same. Starting to give up on Seiko budget quality control

[@westdoc]

I bought this watch when it came out. Great bargain. But, I had to return it to Seiko twice when it just stopped running. And it runs slow. About a minute every three or four days. Frustrating. But I am wearing it now.

[@gs4854]

No screw down crown was a deal breaker for me on this watch

[@soundscaperecordings1111]

You a deep sea diver then? If not 100m is enough

[@joshsher6327]

I've had this watch for 3 months now. Like it. But case diameter should be 40mm at most. Case height should be lower from 14.5 to 13mm. And if Seiko makes it water resistant for 200 meters like its predecessor the SKX, it would be the perfect GMT dive watch under $500. By the way, a true GMT movement is overrated. Sure, you can move the hour hand, but setting the date is a pain. The date on a caller GMT is a lot easier to set.

[@MrSandperson0]

SSK transplanted into a SKX!?! 🤯

[@ufrl0216]

Funny I never heard the term "true GMT" before this watches release. Could the Swiss be upset the Japanese cleverly converted their day complication to GMT providing extraordinary value?

[@justmeeagainn]

It’s more the case that this GMT works backwards. The hour hand is supposed to keep track of local time and have a quick-set feature.

[@kazuyukitomita891]

I get it now that you have explained it to me, but I wouldn't have thought of that by myself. ⭐🕒

[@SilverBackELTorro]

The selling point here is the looks more than the build and movement. Not sure at that price point.

[@idontlikestuff]

From what I know you dont use watches like these any more when you dive. Unless you're a poser of some sort. Its funny how nearly every watch reviewer I've watched on this lists 100m as a con. Yet they probably never dive. This watch makes the prices on Rolexes etc seem like a joke to me. Great watch.

[@idontlikestuff]

Your video was great by the way. I dont count you for that comment on the wr depth.

[@SrJonAnthony]

Iso divers are for diving, WITH a dive computer. This is a sport diver, not real diving lol, young people are always saying bs about these, they dont understand design aspects/logic.

[@morrieglick4137]

Wonderful video. I like the ssk003 very much. My only hesitation is how scratch resistant is the hardlux crystal versus a mineral crystal. I know sapphire is the best. I have a Buleva with mineral crystal - the scratches drive me crazy. Thanks in advance for your reply.

[@DIYWatchClub]

@@morrieglick4137 Hardlex crystal is just a slightly better mineral crystal. It's not a big improvement in terms of scratch resistance. Aftermarket replacement sapphire crystal might help you in that department

[@blueeyes183]

how much it cost to upgrade into saphire for this watch with cyclops

[@adenovirus.]

I want a white face so have to go pagani homage with seiko movement.

[@SpaceMagicStorm]

If it had sapphire window and a clicking ceramic bezel it would be perfect i would pay an extra couple hundred for those features if I had to but truthfully I doubt it would break 600 cost. Also would like the s logo on the crown but that's a personal preference thing.

[@fortbend7517]

I really wish there was a way to get rid of the seiko 5 logo on these dials. It would be the perfect sub $500 watch if they did away with it.

[@SrJonAnthony]

Seiko 5s are their own line so no reason to do that lol

A very good watch but IMO, a raised cyclops date window without a sapphire crystal is a deal breaker for me. I would go with the Citizen GMT/Diver BJ111-86L hands down.

Good but a 5 Sports is not a diver, the comparison with SKX makes no sense and btw the root of that case is the 7548 (1978) not the SKX (1996).

I know it's not a GMT, but I end up buying a TISSOT PRX power 80 automatic instead of a Seiko GMT..... it is almost same amount of money 500-600$... and I got a saphire crystal, swiss good quality movement compare to the Seiko's movement that looks very cheap and unfinished.... it is almost like a 200-300$ Seiko 5 quality....except the GMT function.... so really you are not getting a bargain. I think I will wait till more GMT on market and this GMT will get push to more sub 300$ price. the GMT is a really low cost addition to the Seiko cheap movement ..probably only cost few dollars and they charge 200$ more for the watch...

Ironically, it will have an NH34 (made by, cough cough Seiko) because those Chinese brands are not capable nor have the knowledge of making a movement themselves. Let the big boys such as Seiko, Miyota make the movements. Keep buying your cheap, high spec. homage watches.
