Casio Oceanus OCW-S100 Full Review (Featuring the OCW-S100-7A2JF)

[@michelk5]

I was interested in a titanium Oceanus but it was a bit out of my budget. So i bought a Lineage LCW-M100TS instead, and my god this watch is gorgeous and has much more features. I sometimes put a nato strap which transform it from a very light to a super light watch at 40g only. For those who want to try titanium, try this one instead!

[@alaththar819]

Agree.... That was my case, but instead LCW-M100TS, I got LCW-100T. Because even LCW-M100TS was above my budget, and I got The LCW-100T second hand. Same function minus Count down timer, but better in Over all lay out symetry. 😅

[@michelk5]

@@alaththar819 i like that one too and was hesitating at that time but i wanted my first titanium for the light weight. Very nice watch as well.

[@garman333]

I have a Waveceptor, Lineage, and Oceanus. I think that the Lineage is the "Goldilock" of the three and is the best value.

[@tablameister]

I got the LCW-M100TSE-1AJF - titanium, solar, and atomic time for under $200 (shipped from Japan). Great watch!

[@MarkM58]

Welcome to the Oceanus club. You got me into G-Shocks (I now own 28). I have the OCW-T200, OCW-S5000 Manta, and OCW P-2000.

[@emptyshells5335]

You have many fine time piece's and i enjoy you sharing them with us Mr. Timekeeper

[@michaelkaliski7651]

Just received one of the black faced S100 from Japan. For a watch that is intended for the Japanese domestic market, I was surprised to see CE and UK approval marks etched on the case back. Clearly production is still current and in full swing. Beautiful looking watches for the price and truly set and forget pretty much forever.

[@garman333]

I love seeing all the watches in sync with other.

[@GoodTimekeeper]

I figure that regular viewers expect synchronized watches in my videos so it’s one of those details that I check before the camera starts recording. I forgot to synchronize the tan-color, big digit watch I used for a size comparison at the last part of the video. Sorry about that. It was a few seconds off.

[@John-P]

I have this watch, although I have not seen one with roman numerals before, it is my best and most expensive watch, and I find it absolutely brilliant, the integrated bracelet doesn't bother me as I paid a premium for Titanium I'm happy to keep it, the only negative is only 2 micro adjustments but you do have half links which are a big help, and when you are adjusting the bracelet it is a pin and collar which for the first time I found a little stressful but with patience I did it...stay safe

[@thomaslinton5765]

Got the medium blue version for $450 delivered from japan, brand new. I am VERY happy. Thank you for all your videos.

[@talesfromthejundlandwastes5498]

Just took the plunge and bought an Oceanus, based on what you showed here - went for the OCW-T200S-1AJF. Excited for delivery!

[@bobbyboldy]

So nice to see a watch of this caliber(no pun intended) in a video of you. This model is one of the watches that I have considered as a grail watch but decided against it because of the integrated center links that make it next to impossible to put it on a band. I am still very curious how you experience it.

[@GoodTimekeeper]

Some folks really like that OCW-T200 model because it looks a lot like this (maybe with different color choices) and you CAN easily put on a bracelet, strap or band of your choice.

[@ftrctyvreycertcewtcwrgcwef6000]

Im late to comment, but im still gonna voice my opinion. Everywhere ive read about this watch, thats the only downside to this watch. For me, its not a problem, but some people prefer nato. I wonder what it would take to modify it yourself for a third party band to work. If i recall correctly, the t200 has a detachable band right?

[@bobbyboldy]

The T200 comes with a bracelet but does not have integrated center links so strap and bracelet changes are easy indeed. @@ftrctyvreycertcewtcwrgcwef6000

[@CTRable]

impressed with those features and layout

[@Tris-ge1oy]

I've been considering one of these in the black dial, but when I saw this review I knew this version was the one I wanted. Mine was also purchased used, but frankly, it looks nearly new. I'm so pleased with the intelligence of how the watch functions, as well as the fit and amazing finish. The bracelet is very comfortable and the watch wears beautifully. I love having the markers hit every time, and the roman numerals at 12 and 6 really work for me. The multiband 6 adjusts the time overnight, every night, which is great. Someone said this watch has no soul; perhaps not, but it has everything else. I appreciate the in-depth review you gave on this watch. Enjoy it!

[@international_dave]

Nice watch and a great review. I hope to add one of these to my collection in the near future.

[@rudolfabelin383]

Best demonstration of this watch that I've seen. Greetings from Sweden.

[@Mettleh3d]

I can imagine the head scratching involved with all the crown-date settings without the user manual 😅 Very impressive Casio

[@severnsea]

I totally agree with your buying philosophy and I just ordered the T200, largely based on your review. This looks like another great watch that would not look out of place in a collection of watches costing £5000 each. Madness in my opinion. I get why wealthy people buy the really expensive high end brands which often have a unique design, but when you're buying something that looks the same as a watch costing 1 to 5k or so, what's the point? Sapphire is sapphire, it's extremely hard wearing and while watch geeks always claim you get far better quality coated stell or titanium, look at worn Rolex's and the like, they still scratch. My last Citizen stopped working after 15 years but it doesn't look any worse than any high end watch I've seen that has been used daily. The Oceanics look like great watches at prices that are not going to get you into trouble if things go wrong and look the part too, crazy that Casio don't sell them outside of Japan.

[@lislearnitalianwithsongs]

Well, grazie for another super interesting video! I always wonder if quartz watches like this one could be serviceable. After all they are “premium pieces“ and they deserve this chance, even though they’re not very likely to need to service any time… Thank you again for a great video! Grazie!

[@Cubingjay]

Great showcase of the functions of this watch. Very informative, thank you

[@4Memf2dafizzo]

Hello Greg. Great review! I have the Oceanus OCW-T200S-1AJF with the blue dial and I have to agree with you that the polishing is outstanding with a mirror finish. The overall finish including the brushing punches way above the price of the watch.

[@GoodTimekeeper]

I may have some thoughts to share later this month about that watch. Stay tuned.

[@psychpearl]

Great review - it is a model which I had not seen yet. But Greg, it seems you can sit around and play with it while waiting for a movie. I envy your collection and savvy - cheers from a happy PRW3100 owner.

[@GoodTimekeeper]

Yes, I managed to make a 25-minute video about a watch which has no alarms, no timers, no beeps, no lights. So I CAN play around a lot!

[@lskovly]

Got the OCW-T150 (blue dial), a great watch.

[@peterrich5449]

What a stunning dial to match the finishing.

[@nickbeech501]

What a gorgeous and intelligent watch, I would love to own one of these. Many thanks for the informative and entertaining video.

[@shawnmartin1306]

I personally won’t wear GShock. However, my 7 year old had been wanting a watch because he sees me wear them. I actually put my Grand Seiko on him and it looked good. Ironically I could have removed enough links to fit his wrist. I just couldn’t see sending him to school with a watch that I paid $2,400 for. It was quartz which over time after having watches running at 4hz I just don’t like the quartz movement of second hand. I have Tudor I wear mainly. The watch I wear for outdoors that I don’t care if it gets messed up because it was pretty cheap is my Tissot PRX80 auto. I do love that watch and it was pretty cheap. My Hamilton is really nice too but it’s so heavy. I actually found this video because I saw this watch on Amazon and eBay like you have but I’m blue dial. Looks like the white is better looking. Just not sure I can buy a quartz watch though. Tough decisions

[@bernardofernandez6138]

Great video Greg! I just found and ordered a used one from japan and I'm really looking forward to getting it and wearing it, keep up the good work!

[@bernardofernandez6138]

I got mine last night, Since it was a used model it didn't come with any manuals or box but it does fit my wrist just fine ( I have to remove a link from the bracelet ) but other than that it's a beautiful watch, I found you video very helpful to set my watch so I want to thank you for your time to do all this reviews, Gracias Señor Greg

[@PineapplePizza1]

What a beautiful watch! I hope it comes back in stock.

[@gwynwilliams4222]

Great looking watch great video enjoyed immensely 😊

[@n2awa]

Neat watch. Thanks for showing the features.

[@mosfet500]

Thanks Greg, The Oceanus is a wonderful watch!

[@Leon-uj7pc]

I like the looks of the S100 series but I could never get the bracelet to fit me right. Plus integrated bracelet meant no ability to change to a strap. I ended up with the stainless steel T200 series. Of course then I bought a Oceanus G1000 with the GPS sync and the MB6 sync and never looked back

[@aliveli-hq6zk]

Good looking high quality watch

[@strannostrannovasrr]

Thank you. That was a very informative review. Is the hand alignment also being applied on the seconds hand so that it hits the markers perfectly?

[@michaelkaliski7651]

Yes

[@hankcromer2935]

Would love to have one of these with the black dial for use on occasions where I need something a little nicer than my Mudmaster. However, I think the wife might kill me if I got one. Very nice watch.

[@daynevickers1079]

Enjoyed your review. I'm considering this watch, but have one question... doo the new models of this watch have the on-the-fly micro-adjustment Casio offers on other models? I'm particular about the fitment of my watches, and even though this one offers half-links, with only 2 holes of micr-adjustment, it might not be enough. Thanks!

[@GoodTimekeeper]

Yes, I think I have seen some guys talking about a sliding micro adjustment on the newer Oceanus watches. I don’t have one but it looks like a great feature.

[@daynevickers1079]

@@GoodTimekeeper Thanks Greg

[@MrTikey4]

Hi Greg, I own a Oceanus T200. I am an occasional diver but I do not go very deep. Would it be worth buying a Duro for whenever I dive, so I do not damage a $450 watch, or do you trust the T200 for swimming/ occasional scuba diving? I watched your video about water resistance but the thing that worries me is that the T200 does not have a crown that screws in, as opposed to the Duro. Is that feature really necessary?

[@brocklanders6969]

I have the S100 in black dial and the T150 light blue dial.

[@jeffshaw4039]

I got a Oceanus 150 its like your watch but with blue highlights.

[@zguo4092]

Hi Greg, can you review this little one? Casio LINEAGE LCW-M170TD-7AJF, thanks

[@thomasdrew5328]

Great review, thanks for that! Would you ever consider a Junghans Mega Solar? The Max Bill one for example is similar in functionality but with a Bauhaus inspired design, also it's a HAQ and is +/-8s per year without the atomic signal.

[@GoodTimekeeper]

The only issue would be a high price (I am always hoping for a bargain) but I suspect it’s a great watch.

[@thomasdrew5328]

@@GoodTimekeeper true, they're not cheap. But they come up second hand every so often.

Man the prices online vary alot ive seen them all over the place from $400 up to $2100 some dude wanted on Ebay. Also you need a new one to really see the amazing polish job especially the SS one. Cheers...

[@loganholmberg2295]

I'm in a simlar situation with titanium casio protrek Prw-60T. I've been waiting 5 weeks so far for casino customer service to send me some links. I don't think I ordered enough so I ordered again so even if I might get my links next week (at the earliest) I could still be waiting at least another month. And the thing is 23mm lugs so good luck finding a temp strap....Ugh.😪😪 I hate being tall. Nothing ever fits.

[@andrewmarriott4033]

Great review love this watch 👍

[@thomaslinton5765]

Did you get your extra link(s)?

[@SuperMrgentleman]

It is nice. I do prefer watches with hands that caress the markers though.

[@GoodTimekeeper]

I’m not sure what that means but if it has anything to do with the second hand pointing precisely at the markers then I can assure you that this watch does it. If it doesn’t look right in this video it’s only because of the camera angles.

[@SuperMrgentleman]

@@GoodTimekeeper I mean the seconds hand comes out and overlaps with the seconds marker, and the minutes hand at least touches the tip. But I'm weird, I'll admit.

[@GoodTimekeeper]

No problem. Knowing exactly what you want is just fine.

[@anonymoussurname]

We have the same mindset. I’m not spending over a $1,000 on a single watch. I did my research and sub thousand dollar watches can’t easily compete with a Rolex thanks to modern manufacturing processes, wide availability of materials, and great quality control.

[@jeffshaw4039]

That's a nice watch I didn't know that casio made a high end watch.

[@GoodTimekeeper]

It’s a little bit of a secret, I guess, since the Oceanus watches are apparently for the Japanese domestic market. Thanks to eBay, Amazon and other websites which will help me order these from Japan, I can try some uncommon watches here.

[@damyr]

You should see titanium square G-shocks. They go for $4-5 k.

[@GoodTimekeeper]

I like the idea of a cool titanium square but $3,500 or $4,000 doesn’t quite sound like the kind of price I would consider. Also, I failed to mention that the watch in this video is just an entry-level Oceanus. They have some models which cost a LOT more!

[@damyr]

@@GoodTimekeeper Yes, that's their premium series called MR-G. They even come in various colors and themes, with special laser etched motives. But I would never buy something like that, even if I'd be richer than Elon Musk. Any watch beyond $500-600 mark is just stupid waste of money.

[@talesfromthejundlandwastes5498]

What about a Grand Seiko Greg ?!

[@damyr]

Greg is not an idiot. He buys only Casio.

[@talesfromthejundlandwastes5498]

@@damyr I think Greg is capable of answering for himself.

[@damyr]

@@talesfromthejundlandwastes5498 And he won't answer on such stupid question. If you watched at least this video (let alone any of his other videos), you would learn he doesn't buy expensive overpriced watches. Those are reserved for braindeads only.

[@GoodTimekeeper]

These days it seems like I never go to any stores where you could see high-end watches in person. Maybe if I saw a Grand Seiko in person I’d find it to be super attractive. But, at this point, they just aren’t on my radar. And the price just doesn’t quite fit my style. But I give all due respect to anyone else who has one (or two, or three…).

[@talesfromthejundlandwastes5498]

@@GoodTimekeeper Yes, I'm in the same frame. The finish on your Oceanus is very beautiful and overall it's an extremely lovely piece. And that's very fulfilling without the outlay of up to 5k. Though, watching videos of superb engineering and finishing on the Grand Seiko (particularly the Snowflake) does fascinate me.

[@ZeginMakesMusic]

My first 5 watches cost sub $200. My 6th watch was a Raymond Weil Chronograph. And now after wearing it, I've become spoiled. Low cost watches feel like toys. Maybe it's better you don't drop 1k on a watch because now anything under 1k I'm reluctant to even look at.

[@damyr]

@@ob4149 Vast majority of mechanical watches are overpriced and overrated. But Rolex is even beyond being overrated. It's absolute madness to spend $5+ k for a watch, when you can buy Oceanus for a small fraction of that, and it's still infinitely better in every way.

[@gregsmith7821]

While the Swiss have invested in publicity, to convince us that old, expensive watches are what we all should aspire to,,,,,, the Japanese invested in technology and developed ridiculous good value, amazing, top performance time peices. Laugh at the people who aspire to Rollex but wouldn't touch a Chinese copy. Wear what ever you like but, if timekeeping and quality matter, by a jdm Citizen Attesa, Casio Oceanus, Seiko or, if your pockets are deep enough, Grand Seiko.

[@GoodTimekeeper]

Agreed. I’m not interested in telling others which watches they should like and I don’t buy watches with thoughts of how much money I could get from selling them. I like certain features and atomic accuracy is at the top of my list. So this Oceanus really is the right expensive, “luxury”, fancy watch for me.

[@heidyaji]

Beautiful watch, Greg! But not very intuitive to set...

With any luck, you only have to set the time zone, which is pretty easy to do, and then you’ll never even need to know how to set anything else.

These 'integrated' bracelets CAN be changed to different straps if you want to.

[@thomaslinton5765]

@@gazrev7671 Citizen could make these "integral bracelet" watches so a replacement strap is easily attached - without filing off the protruding part of the case or by cutting a notch in the new strap. Or Citizen could have skipped the protruding part of the case between the lugs. They do the latter on some of their watches.
