I posted this one a few days ago. My 27 year old quartz Bulova Railroader. Later that day I found it to be 5 minutes slow! I rarely wear it, so this was a surprise. I stripped it and cleaned on Saturday, and it has returned to being its customarily reliable self.
Hmm well I got Covid at the moment and feel like I am 110 lol.
I wish all watch companies kept a production register and serial numbered their product but unfortunately its not the case with many Swiss watch companies even today. Maybe somewhere Titoni have an early archive of production numbers but I am not aware of it.
