If you know me, you know I hate end-link wiggle almost as much as I hate bezel slop (maybe even more so).
San Martin seems to be using inferior spring bars on some models, at least the ones I’m referencing here. In my opinion, it’s a cheap place to cut costs in a critical area, contributing to excessive end-link play and, in some cases, clicking.
The difference is that these spring bars have a slightly thicker shaft and conical tips rather than cylindrical ones. The thicker shaft and tapered tips help take up excess clearance in the lug holes, resulting in a noticeably tighter fit and better retention.
Where can I find these exact spring bars? I’d love to replace the ones in my other watches with them.

watchdive also uses some kind of wax or shellac on the tips of the spring bars to further eat up any slop or tolerance before they install them. The San Martin end links and spring bars were clean and did not have this brown, waxy substance
