What oscillator are they using? Things like the DS3231 (which are temperature-compensated crystal oscillators) only do about +/- 2ppm, which is about +/- 1 seconds per week. You can tune them to do better (mine has been running at about -0.007ppm for a while), but on the tin, they appear to be worse than what you reported. (And they go to great lengths to be that accurate.) My main conclusion is that I want a watch w…

I imagine the actual drift rate is normally distributed around 0 with 2 std deviations within 2 ppm or similar. Maybe I'm wrong. But I recall having not adjusted the clock for longer than a year and it only being about half a minute off. I just like to tell myself I got an accurate one out of the batch :P

Quite possible. Also possible that they are just doing a good job!

Yes, the “auto-only” base Seiko movement is pretty annoying, if you’re not wearing it everyday. For anyone who hasn’t experienced one, imagine that when you want to wind your watch, you have to turn it dial up in your hand and rotate the whole watch for 30 seconds (the so-called seiko shake) such that you spin the rotor inside. I ended up swapping my SKX movement out for a hacking / hand-winding movement too, much be…

That sounds terrible lol. And then you have to find some other clock to reset it after you rotate it. Is 30 seconds always enough? I'd be nervous of it running slow.

Yeah, it was just annoying enough to cause me to learn how to do surgery on my watch. It’s the only downside of [some of the] low-end Seiko’s.

30 secs was usually enough for me, but depends on how active you are afterwards—-if just typing at a desk, you’d probably have to do the shake longer than that.

Edit: actually answered the question

Timex and Armitron are the two others that come to mind.

Also Braun. Beautiful but pricey. https://braun-clocks.com/collections/digital-watches

So that’s where the Apple Watch came from! https://image.sportsmansguide.com/adimgs/l/6/609716_ts.jpg

I have 3 Oceanus (Casio boutique brand) watches. The two that I got in Japan actually have “Casio” under the “Oceanus” label. They are great watches. Not especially cheap, but they are far better than my kilobuck Junghans. I wear none of them, though. I have been wearing my Apple Watch (cheaper than the Oceanus watches) for the last couple of years.

Nick Shabazz on YouTube has good reviews of one of the limited-edition top-end Oceanus models, OCW-S5000C-1AJF: https://www.youtube.com/watch?v=PTXFG27NNhI and the entry-level OCW-T200: https://www.youtube.com/watch?v=ELn3ubqjVWU There's a few good sites offering export of Japan-only models from the various Japanese manufacturers: https://www.shoppinginjapan.net/ https://www.sakurawatches.com/ I'm trying to find enou…

No, thankfully. Only one of the watches was purchased in the US.

I did try to get the Junghans watch fixed, and that did not end particularly well (it did get fixed, but I didn't make any friends). I brought it in the US, but there are a lot of places that sell them, but don't fix them.

I have a OCW-10DA-7A (Wife's watch)[0], OCW-S100-7AJF[2], and a OCW-T410TD-3A[2]. The last two, I got in Tokyo.

G-Shocks are a big deal over there. They have G-Shocks that are a lot more expensive than these were.

I got a Casio watch from Amazon about five years ago, there was a deal on and it was about CAD$20. A budgetary driven decision, for sure! But it's been fascinating to see, over the years, how many times I've been approached (in a coffee shop or some other public place) by serious Casio enthusiasts, keen to ask about my watch and to show theirs. There's so many variations, colours, limited-runs editions... I seem to h…

I got a couple of casio watches from Amazon years back. Then I brought one in a physical watch store and realized that all the watches purchased through Amazon were fakes. Especially the strap is so much better on the real thing.

Any idea where a person in Canada could purchase one? Not having any luck other then amazon

I agree on all points, except I prefer my watches mechanical, rather than electronic. So I got one of the cheapest Seiko automatic watches. Being mechanical it's obviously going to cost more and keep time much less accurately than a quartz watch. Other than that, I identify with your comment. The cheap automatic Seiko is always there, and it always works. Don't have to worry about putting it away and then needing to…

I accidentally damaged the spring on the balance wheel while adjusting my Seiko 5. I then bought a new Chinese NH36 movement for 30$, which can also be wound by hand and is hacking (movement stops when adjusting). I also had to transplant the dial/day dial and get a new crown. I love mechanical watches and would definetely be a watchmaker if I was born before the quartz revolution.

Where did you get a NH36 for $30?

I got one of these guys watches, it has an RFID chip but I can’t think of anything to do with it. It looks really cool though. The light is nice too since its bright enough to use as a flashlight when its dark enough.

I use to work at a place that included parking in rfid activated ramp. I always wanted to clone my badge into something sewn into the wrist of my motorcycle jacket so I didn't have to fumble for my badge while entering and leaving the ramp. In a watch would be perfect.

How would you go about doing something like that? Are RFID chips that insecure?

There's definitely a dearth of English-language info on Casio's premium offerings, especially the older Oceanus stuff. I gather you must have purchased your wife's watch during the brief period they tried to make a go of the Oceanus sub-brand in the US?

There's all sorts of bizarre sub-variations, too. I saw a similar women's Oceanus on eBay last fall, with English-language Discovery Channel Shark Week branding, and the seller in New York was dumping it for cheap because they couldn't get the radio sync to work. Turns out it was a model that was only set up to sync with the UK and German time signals. Older Casio models also only say Multi-Band 5 as well, because, I guess, the Chinese atomic-clock broadcast hadn't been set up yet.

I love the F-91W and wore one for years before switching to an Apple Watch. I don't see myself switching back to the Casio, but I do miss it sometimes and wanted to bring as much of it over to the Apple Watch as possible, so I put the Casio band on it [0], but I haven't been able to put together an Apple Watch face that resembles the Casio. Has anyone else tried this and had any luck? [0] https://jamesbvaughan.com/ca…

What home screen is that on your Apple Watch?

It’s called “California”, the circle variant in cyprus green.
