Is this reasonable to expect from a good quality service?

Hi, folks-- a couple of things have happened recently that have made me question my watchmaker's skills and I am wondering if I am being unreasonable or if I should find a new watchmaker.

The issue is the same for two watches, a 105.012 Speedmaster and a Zentih A277: Both received a full overhaul within about the last two years, and I recently noticed--separately-- that the chronos on both are not working correctly. The Speedy's reset button stopped functioning entirely, and the Zenith reset doesn't reset the hour counter (only the minute counter).

I tested the functions when I first got the watches back--indeed, I had to return the Speedy right away the first time because the chrono sweep would get stuck.

I don't wear either of these watches on a daily basis. They get worn in rotation, sometimes not at all for months, then sometimes a few times a month, then again infrequently, and so on, in no particular order except as my mood dictates. I'd estimate that I wear each watch no more than, oh, 10 times per year?

I never use the chrono functions in any case, but for some reason I decided to try it on the Speedy recently and discovered the issue with the reset button. That led me to try out the Zenith chrono and discover that problem, too.

So: Are chronos that are 50+ years old just never going to remain reliably functional, given their age, or should a serviced chrono of this age be expected to reliably perform for 4 or 5 (or some number) of years?

Thanks, Tony. Perhaps I was not clear: I did test them immediately after getting them back, and they worked at the time. They stopped working sometime between then and now, having only been worn 10 or 20 times over the two year period.

In any case, they are out of warranty because the service is only guaranteed for one year.

I suppose I should have tested them near the end of the first year.

Your watchmaker….is he a butcher during the day who fixes watches of an evening? ‘cos if he is then I have absolutely no doubts as to his ability as a butcher

Well I didn’t think so, but maybe I should ask him for a steak and see how it goes.

Be careful of his sausages though, they might have leftover watch parts and chopped up watch straps in ‘em!

Thanks everyone. As I feared, I either have had very bad luck or my watchmaker is not up to snuff.

Maybe that’s the problem… he’s always on the snuff!

Yes my guy has been around the block, too, so maybe it’s age. A shame because he is very well priced!

Yes will do. I’m a firm believer in honey over vinegar.
