··Omega Qualified WatchmakerI already have a couple automatic watches but just got a Speedmaster Professional a few days ago. I find it to last merely a day. I use the chrono once or twice a day for about 5 minutes.
I'm a little bit concerned as I don't know if I don't wind 'enough' in fear of overwinding or if my new bought watch already has some trouble
I'll keep an eye on it for sure and might return to AD if necessary.
If you don't know if you are winding it enough, that tells me you are not. Wind it until you can't wind it any longer - there is no guesswork here.
