I have a T023 V3 that has stopped working properly, ie it still runs but I can't set the time anymore. Instead of getting it replaced or repaired by the manufacturer, I was thinking of upgrading the PT-5000 to an SW-200, which, as far as I know, should be interchangeable.
The local watchmaker however is telling me that the original caliber was "modified" and they can't just replace it, and is also quoting a pretty high price for the SW-200. They're recommending a complete revision instead, for a price that is also higher than the whole watch. Do they just not want to do the switch for some reason or could there be actual modifications to the PT-5000 that make this not possible?
