: My 3 Oysterquartz. Production ceased in the late 90's. Although
: COSC Chronometers, they were certified under the less stringent

: unable to meet the new 30 s/year accuracy standards. They were,
: however, thermocompensated despite using early to mid 70's
: technology.

Roger,
Nice grouping of the Oysterquartz. I don't believe I've ever seen 3 in one spot before.
I curious to know how accurate they are month to month. Reason being is a friend has one and its a pertty poor
timekeeper all things factored in, its been back to Rolex for an overhaul but came back keeping the same time. It looses
several minutes a month. Nice grouping Roger.
