Hi, We are servicing a TV-case 176.005. There seems to be a sort of tension ring missing (Outer Ø ≈ 32.45mm). My problem is that I don't know what it is called, and I cannot find it mentioned in Omega's parts register. Can anyone help with a name or part#? Thanks for looking.
Think outside the Box. Every maker, who used caliber 5100, had that ring to pres down the movement. Orfina Porsche Design for example ...
