It is finally time to dissect and opine on the 3940. Erik & Max break down series with some nuances you may not expect. This includes hallmarks, Singer vs Stern dials, Series breakdown, and thoughts on what truly matters here. And that’s just the first half of the episode, with the second dedicated to covering the vast majority of all major references since and what to pay attention to. It’s the second half Patek Philippe of the ‘pure’ QP bloodline this week.
