First I must say this is an excellent watch forum.
I received a non working Seiko 6139-6005 for free. It belonged to my grandfather, the watch is mint, never opened up. I had it serviced locally here in Arlington Texas at a vintage watch shop. The watchman replaced all seals, main clutch spring, a worn gear, and cleaned & oiled movement. The is now running smoothly :). It is running fast though (1 minute per 24 hrs). I called the watchman he said to give it 2-3 weeks to settle in. What does that mean, what takes place during this settle in time??
What is the realistic accuracy of this movement, so when I take it to the watchman in 3 weeks I'm not expecting something unrealistic as far accuracy when he tweaks it?
thanks in advance
