I own a vintage chronograph, Mathey-Tissot I believe, with a movement that has been trashed. Enough that the chronograph function isn't working. I believe it is a cal 28.9. I have taken it to multiple watchmakers who are unable to repair.
So I am wondering, can I use any other cal 28.9 that I find and have someone swap that movement for the movement in my watch? For example, there is a Tissot with a 28.9 on eBay that looks very much the same, just with rectangular v round pushers.
My goal is to save everything else: case, dial, hands, although truthfully I am not sure what really is original to the watch.
I don't care about the cost as it has sentimental value. I expect the amount I pay to get this running will be more than the value of the watch.
Any info welcome.
