    Impressive COSC Certificate

    I just received a watch with this COSC certificate. The accuracy measurements seem better than average. Anybody want to guess what the movement is?

    What are the most accurate COSC results anyone has received with a watch?

    Seiko for $1800 in around 1968 was +/- 0.175 per day. I find the accuracy of mechanical watches a bit academic these days, when access to an accurate clock is as easy as looking at your phone. I am more interested in things like reliability.

    Means nothing if your watch is greeted by a door knob.

    Pretty impressive timing, whatever the movement. Who still provides COSC certificates? I think Omega still does if you pay them. I bet it's Omega's antimagnetic coaxial.

    Nobody cares anymore about accuracy as people buy RMs and pretty dials for filling their ego. Those who do care get spring drives.

    I think the low sensitivity to varying temperatures is a good sign. People underestimate this parameter. You should be glad you got this promising temperature value.

    But you know a test certificate is one thing, the proof of the pudding is in wearing it on the arm.
