These are based on known watches observed, and other sources including MWO. This source has confirmed some of my onservations and refines others, and they do quote more accurate figures. I urge you to buy the book.

2915 serials are very vague. Be aware that seamasters also had 15m serials and no extract can confirm. I believe 1599 is a good serial.

*MWO quotes an earlier  finish serial

**MWO quotes all the last three sub references together.

***So rare my number here is more of a guess
