Over 45 years old, but super accurate….Update

After nearly three weeks I have adjusted the time on this Crystal Date this morning – it was about 30 to 40 seconds fast. I reckon therefore that the watch is running at most at about +2 seconds a day. Nice 🙂

    Hi!

    That´s near COSC perfomance! You should send it to there and let them test it. There´s only little but: The certification costs about 5000$(or € or £, can´t remember which one…) 😀
    And other thing is that how they react to Japanese watch, it could be so, that they do it only for Swiss watches.
    How about it´s service history, have you got serviced it in recent past?

    Regards, Marko

      Hi Marko – if that’s all it costs I might send 2 or 3! 😉 I don’t know if they look at non-Swiss pieces now, but I know that they weren’t happy in the 1960s when Seiko started out performing the Swiss makes and I believe this led to the COSC competitions being abandoned.

      As to service history, I have no idea 🙂 I haven’t had it serviced, and I don’t remember if it has any service marks inside the case back. Will have to take a look later.
