Re: [time-nuts] Casio Wave Ceptor wrist watch - quick accuracy test
I posted about my G-shock watch on this forum probably about 10 years ago. Go look them up. I found mine superbly accurate and being in Tasmania I cannot connect to any LF service. After a while it started to get a little worse and I found you can take the back off and calibrate it. My rechargeable battery has just started to fail and so I've ordered a new one.

Re: [time-nuts] Casio Wave Ceptor wrist watch - quick accuracy test
I should have mentioned that my Casio (module 3405) is a G-Shock "diving watch" with a 20-bar (~200m depth) rating. In so far as possible, I never take it off my wrist (TSA check points being the occasional exception), and don't want any leak problems even though I never dive. I once bought a watch rated at 20m, and it only lasted about a month before it leaked. Apparently normal living stresses are equivalent to diving to moderate to substantial depths.

Re: [time-nuts] Casio Wave Ceptor wrist watch - quick accuracy test
I think you guys won the luck of the draw. I have had a Casio WV200DA-1AV Wave Ceptor for a while, module 3140. Nice watch, but it gains about 1/2 sec per day when not synchronized. I recently got a Casio GW-M5610 G-Shock, module 3153. I have not run it unsychronized, so have not checked its drift, but other G-Shocks have been quite good. It is the higher-end line with tighter specs and they actually have a trimmer inside.

But I find that visual/aural coordination is a poor way to do business- if the error is near zero (or an integer number of seconds), my eye/ear/brain will shift to make it look like it's "right on" within a few seconds even if the initial look says it's a little bit off.

Re: [time-nuts] Casio Wave Ceptor wrist watch - quick accuracy test
I bought a Casio 'atomic watch" about 3 months ago, one which uses the '3405' module. I've also been running checks with radio setting turned off, and mine is coming in at just under 1 sec per month, based on seeing how long it takes to drift one second. But I find that visual/aural coordination is a poor way to do business- if the error is near zero (or an integer number of seconds), my eye/ear/brain will shift to make it look like it's "right on" within a few seconds even if the initial look says it's a little bit off.

[time-nuts] Casio Wave Ceptor wrist watch - quick accuracy test
Hi! There seems to be some kind of comeback going on with 80's style digital watches. You may find replicas of some 80's models or even re-makes of the original models from original manufacturer. So I decided to get one. As a time-nut my primary goal was to have radio controlled 'atomic' model. So I ended up to Casio Wave Ceptor WV-59DE-1AVEF. There's many models available from basic digital models like this to very nice ones with with full titanium body (analog style). But because of the 80's is hot it had to be digital... Wave Ceptors suport all time signals formats (US, UK/German and Japan) and correct standard is automatically selected when home city is set. One of the first things to do was to test the accuracy with radio syncronization turned off. Correct time was fist set with DCF77. Then I switched off the synconization. After beign about three days off there was no significiant visible error on time. In the video we can see however about one frame error, which means about 40 milliseconds. Still that's pretty good result for wrist watch. Also, the syncronization will occur once per day when the reception is good. So the watch must be at least calibrated in the factory.
