How did you check the timing before service to get that +1 second result? It should be from an average of many measurements with the watch in different positions, at a full wind. If the average timing got worse after servicing that would be kind of strange. |

No offense, but if you are so obsessed about a few seconds a day, a quartz watch might suit you better.

You need a timegrapher, measure (after full winding) the caliber rates in 5 different positions (DU, 3U, 6U, 9U, DD), and determine the average value X. |

The 1675 GMT has the micro-stella adjustment system. Following servicing my watch would usually take a few weeks to bed down and then, if I wasn't happy with the timekeeping, my AD would take it into their workshop and regulate it. I think this happened twice in the 50+ years I used it as my daily wearer. The important factor is consistency - if a movement is gaining one day then losing the next day, then something is wrong and it needs servicing. But if it is, say, gaining 8sec/day consistently then it is good, it doesn't need further servicing, just regulating.

I have a 1969 GMT. It runs slow. Always has.
It doesn't bother me. I use my phone for accurate time. Like everybody else. |

If it's still slow or fast after service it may be magnetized. Try to unmagnetized it and take a new reading or re time the Stella adjustment after doing do..
