Did you have it regulated? Asking because my Tudor Heritage Black Bay 79220R uses the same movement, but will lose around 30 seconds in a week... I mostly wear it when I'm not all that active (e.g. in the office, out about in the city, etc.), but it still seems too much to me.
- cpcallen 5y agoThat seems surprising bad. Maybe not strictly out of tolerance, but definitely something that could be considerably improved by having the movement regulated (or perhaps serviced, if required). Is it still under warranty?
- usrme 5y agoNot from the manufacturer, no. I bought it second-hand and the seller does offer a 36-month warranty for any mechanical dysfunctions, though I'm not sure whether something like this would qualify. Even if it did, I'm not all that enthused about bearing the costs of sending the watch to way across Europe if it could just be regulated by my local watch shop instead. Am I understanding correctly that if I had it regulated, then it the deviation would be minimal for years to come or how exactly would that pan out accuracy-wise?
- TheManInThePub 5y agoLoosing 4 seconds per day (28 per week) falls within the bounds of accuracy required of a Swiss certified mechanical chronometer and is pretty good. https://en.wikipedia.org/wiki/COSC https://en.wikipedia.org/wiki/COSC [I made a similar comment further down.]
- alexjplant 5y agoNope... came from Germany that way. As other have notes though losing ~4 seconds a day is pretty accurate all things considered. Seiko's 3Hz movements can gain or lose _half a minute_ a day and still be considered within spec.
