·Hello everyone
I needed to change a broken rachet wheel (31020) on an Omega 2500, so knowing (or at least thiking) that the base movement is a 2892A2, I went ahead and ordered the part from the bay, which arrived in an original ETA package (see photo). Then, to my surprise, I discovered that that it is not compatible (see photo, exactly same size but slightly smaller square hole).
First, I want to share this with others, so you will not repeat my mistake.
Secondly, for my own knowledge, shouldn't there be an interchangeability between those parts and calibers ? What did I do wrong ?
