Long story short, I've gotten my hands on a gen 3135 that I've fitted with a new hairspring, with the obvious in mind. Most of the sites that I've seen advertised here have at least one model of the DSSD, usually the ultimate with the Asian 25J or the optional ETA 2836. That particular model, which looks pretty good in most other respects, is advertised as being interchangeable with the gen except for the dial and movement. My question is whether that's accurate and, if so, what's the best rep that'll fit the gen 3135. Thanks in advance.
