Hi have been looking for the correct stem for a Seamaster 166.032 / 168.023 case and according to the 751 / 752 technical documents there are 2 different stem design styles available:

1- Winding stem length (72205631125):






And what seems to be a 2 piece design (72205631160; winding stem movement part with beak):









Which would be the correct one to go with the OEM stem 069ST42527 ?

Thanks

 

You need the one piece stem, the split stem is for a front loading case like a Seamaster de Ville 166.020.

 

Thanks!

 

Can someone confirm if the correct case back O Ring part number is 088NS0600? Saw that number on the Internet but cannot find it anywhere

 

Yes
