    That is stunning! I have the same model winging it's way to me right now (via USPS). Has your watch been polished? It seems to have all the sharp edges and bevels seen on a brand new OQ but rarely once they have been used, abused and polished.

    That's because everything but the movement, hands and dial has been replaced in the last few years. When I got it from my father in law it was pretty beat up from 30 years in the tropics.

    Hi,

    Well, I got my Datejust back a little over a month ago, and for the last four weeks I've been tracking its accuracy. And I've been frankly amazed with the results. After coming back with the replacement module, in exactly four weeks it's gained a grand total of +0.75 second. That's far, far better than anything I saw with my previous Day-Date. So here's hoping that trend continues!

    I thought Rolex keeps parts for 30 years after production?

    The watch was purchased new in 1980 and serviced for the first time around April 2011 by Rolex USA.

    Not much to brag about by current HAQ standards but not bad for an old OQ.

    What is considered HAQ? 24/seconds a year sounds pretty low to me?

    COSC quartz is 25.6 seconds per year, which many people consider the starting point for HAQ.

    However, the state of the art is 10 or 5 seconds per year, as per Seiko and Citizen. Most ETA movements in practice are around the 10 sec level at least in the first years, even though their spec are higher (just to be on the safe side).

    So, some people now say 10 seconds per year is the HAQ benchmark.

    'Something to boast about' would be anything less than 5 seconds I would say

    We used to consider <20s/y as HAQ. Maybr time to revise it down to <10s/y?

    Re: Finally got around to timing my Oysterquartz

    I'd say 10 SPY or better for modern HAQs, but when talking about vintage pieces I'd be more generous. Anything that employed some method or other to mitigate the effects of temperature changes in order to achieve higher than normal accuracy. The old COSC spec for a quartz chronometer worked out at about 60 SPY and for watches of that era I wouldn't insist on any better.

    Sounds reasonable.
