I recently bought this watch and I love it. It is gaining about 9 seconds a day which is about 4 1/2 minutes a month. Is this normal or could a jeweler adjust it to be more accurate? Thanks  | ||

That could be considered normal/good for this watch which is not chronometer-rated. Your watch appears to have the Longines 507 caliber and probably dates to around 1970. Note that this watch probably hasn't been serviced in a long time and, if you plan on wearing it regularly, you should have it serviced (dis-assemble, ultrasonic clean & rinse, reassemble & lubricate). The watch could be running now with no effective lubrication which promotes wear. Any good watch can be regulated to keep somewhat better time for a specific individual's usage. Note that, due to gravity, a mechanical watch's rate will vary somewhat based on its position dial-up, crown-up, etc. Hence, the average rate will depend on how an individual user wears it (percentage of time in the various positions). | ||

Jimh good information there. I also recently got a nice vintage Cyma automatic and I set it to my Victorinox swiss army quartz watch. I found out that it slows down when the watch gets used during the day, take it off during the night next to the swiss army watch and it recovers within two seconds. It's been doing this consistantly. Once I get it cleaned and oiled, it should regulate more I would imagine. |
