Thanks @mymanmatt for posting this information. Whilst I’m not a watchmaker, it’s posts like yours that educate the great unwashed like myself. One day I will learn to be a big boy and regulate my own watches.
I regularly go out ‘commando’, that’s fine just swinging in the wind but no watch - now that’s almost a crime in my house. Sent from my iPhone using Tapatalk
Looks really nice mate. Whilst strangely I’ve never been into vintage divers this one may change that. If it was your fathers it’s even more valuable to you. Wear in good health my friend.
QC photos are for you to check the watch: to make sure it’s the watch that you ordered and that there are no big faults such as missing lume or detached hands.
If you’re happy with the QC photos then accept it, or if not state what you think is wrong and ask if people here agree with you. Personally, I don’t see anything wrong with it.
In general, the thing most likely to fail is the movement. If you allow for the price of a service when you buy the watch you should be okay. Additionally, if your movement is a cheap 21J then replace it if it breaks or if it’s better quality the have it serviced. The only other thing I worry about are watches with complications such as chronographs. Read up on which ones are likely to go wrong and you can avoid them or adjust your expectations! A native A7750 is better than one with seconds at 6 or 12.
