Some further experiences with ZF IWC 500901 replica:
- the AR is very good, it is easy to catch the moment sapphire "disappears"
- autowind is not so effective if you do not walk enough - as a "desk pilot" it might need some hand winding to keep it running at full power reserve
- my watch stopped due to over banking, quite unexpectedly - brought it to a friendly watch smith: he told me some parts needed a little regulation and it should keep on ticking
Sounds like lever escapement had to be properly adjusted.
- the movement keeps time like a champ! Almost not needed any regulation out of the box
- the power reserve sundial is probably a tiny bit too shallow when comparing to gen photos.
- date start changing about 22:30 (one hour earlier than gen)
