A further update for current and future 321 "Ed White" Special Edition/31130403001001 owners...
called Omega in Switzerland very early this morning. Spoke to an extremely nice woman for about 10 minutes who then connected me with an actual watchmaker.
Loosely quoted as I didn't record him but wrote in shorthand as fast as possible...
"The firmness or stiffness in winding the 321 is very common. It has been reported back to us with curiosity and often concern. There is no need for concerns.
Firstly, due to the hand-assembled nature of the watch each watchmaker in the special area here has their own touch with regard to oiling - while all fall fully into specs and guidelines. The same of course holds true to torque on screws.
Lastly, and most important, gaskets.
While all gaskets for the 321 are to very specific and exact specifications these are always being updated with new batches. Within the batches they are checked but there are always microscopic variations so some windings," his wording not mine, "will be easier while others may or may not ease up with continued daily windings."
I then asked about that final sentence and he said, "My common sense dictates that Use always correlates to Wear... so ease in windings will always appear."
When I asked about comparisons to the 3861 Professional he stated, "The 3861 will always wind with ease. It is designed that way whereas the 321 doesn't mimic but yet is of a handmade, hand assembled, movement of old that reflects modern advancements and current times."
Pretty sure I got all that right as my notes were jotted as quickly as possible.
Anyway, synopsis - easy or firm/stiff winding, it's normal... and only firm/stiff winding, will ease up with time and use.
Thus ends my good samaritan deed for the day.
