Hello together,
does anybody know if the month, day and moonphase discs of the tri-compax subdials of the cal. 285 fit into a cal. 287?
Thanks in advance!

 

Tri compax is 481, 285 is for Compax. You have the calibers wrong I believe.

 

that's incorrect - cal. 481, 281, 283, 285, and 287 are all possible calibers for the different Tri-Compax references.

They should. 285 and 287 have almost all of the same parts

 

Apologies, I had it all messed up...

 

Thank you very much!

 

I believe they are the same size. 9.75mm. Not tried fitting them though

 

Thanks again!
