Like the look of that Oysterquartz- the bracelet gives a very solid look to it.

By coincidence I got my OQ out of the safe yesterday as I'd stored it with the crown pulled out and noticed it wasn't starting again, hum...Got back home and put in a new 357 battery, not the easiest change as you can't "slide" the battery holder to the side like on most watches and there's a "circuit" underneath too, but there it went! Put it on the Old Greiner Quartz Timer and found it was ticking away at 0.02spd, or about 7 seconds per year. For some reason I thought it was 0.2 spd so ahead I went and trimmed it only to realize my mistake when a tiny turn of the screw put it at 0.5 spd...anyway I got it back down to -0.1 spd so I suppose it was worth my time ;-)
They were unbelievably accurate at the time.
When they stop you do hope it is just a battery. The OQ needed a stepper motor. I sent it to RSC and had to pay £1040 for the privilege.
Yes that's the risk with these beasts from the past...
There was competition...
The 1971 Seiko 3823 offered five second a month accuracy, an anti reflective coating and hand fitted minute markers, among other things.
There's a bit more here:
