Speedy Pro 321 Problem ...
Hello All,
I picked up a late '60s Speedy Pro with the 321 mov't. Nice watch, appears to be in good shape (better than I am at the same age ). Seems to keep good time BUT here's the sticking point ... literally. When the chrono is engaged, the movement stops functioning when the chrono second hand reaches the 58-59 second mark. A couple clicks of the top pusher and the movement starts up again, with the seconds counter at 9 o'clock moving again, and another push or two and the chrono seconds begins again ... only to stick when it comes around to the 59 second mark again. Occastionally it will make several revolutions before this happens, and once it stopped at the :34, and once at the :29 mark, but the :59 mark os the only place where it will 'stick' somewhat reliably. When it sticks, gently tapping the case on the desktop gets the movement moving again.
The dial definitely needs cleaning (some discoloration on white hands, hour markers etc.) but the mov't makes me nervous. I have a 72 hour return window on the watch. If these problems are simply related to a lack of maintenance, I had already planned on finding a good watchmaker to clean and lubricate, etc. But if this is a symptom of a deeper problem, would I be better off simply returning the watch and finding another example? The fact that it seems to be working well (other than the aforementioned 'sticking') throws me for a loop.
Thanks in advance for any advice!
