Sapphire Sandwich Running Fast

isgrb · Sep 10, 2020

Hi All - as the title indicates, I’ve noticed my speedy is starting to get really speedy and has been picking up time. I bought it brand new in July ‘19 and is now running ~+20 seconds a day (it’s the current reference). I’m not expecting the same accuracy I get on my Apollo 11 but this seems fast.

Looking for some advice from the experts. Service issue? Keep an eye on it for a few months? Other considerations?

Possibly magnetized. See if your watchmaker can demagnetize it for you.

Agree, running fast like that with a relatively new watch often indicates magnetism. That would be what I would do first, then go from there if that doesn't solve the problem.
