Rolex 1680 - Accuracy

[dave_dave]

Hi all,
Have purchased a recently serviced 1680.
Was over the moon with the watch until I noticed it runs 4 sec slow per day when left on the table facing up. And 12 sec fast per day when on the wrist.
Is this normal for a 1680?
Thank you.

You really can't generalize about an entire reference for a 50+ year old watch. It depends so much on the condition of the movement, how it was maintained, and how thoroughly it was serviced/repaired/regulated. If you want it to keep better time, it might be possible, but you will need to find a watchmaker that is really willing to inspect every bit of the movement with a microscope, and repair/replace as necessary. It could cost more than you want to spend. Most vintage watch enthusiasts really don't care that much.

Sounds like you have a really nice watch and the fact it’s running off slightly for me is nothing to be concerned about. After all it’s a vintage watch and being concerned with it being slow by 4 seconds or fast by 12 is a little over the top. Enjoy it for what it is

Ahhh makes sense.
I was under the impression the cal 1575 was a robust workhorse and with it being serviced, it should fall in range of cosc.
Watch is still under warranty - would it be unreasonable to ask for it to regulated?
Or just leave it as that is how the vintage watches work (sorry it's my first vintage watch and I have no idea).
