Great, thanks for the update. Your watch is running fine, wear it and enjoy. Check it again in a year-ish.

Yes and No. This watch fulfills the Rolex acceptance rate 1st/2nd criterion, the min./max. amplitude tolerances, and the beat rate limit.

Nevertheless, the vertical amplitudes at t = 0 h are not optimal (Bas: 230°-240°), which is also reflected by the 24 h amplitudes, which are only slightly above 200°. In addition, the 24 h vertical rates are all negative, only compensated by the horizontal rates, which keeps the average rate (X) within specs.

It would be very interesting to measure the isochronism (along the full power reserve) of this new (06/2025) watch.

Depending on the owners wearing habits and frequency, I think this 3285 will fall outside Rolex specifications within the next 9-18 months.

I will be sure to keep you all updated. This will be my daily indefinitely.
