We're on summer hours, but we wanted to keep something in your feed as much as we can — so this one comes from our Watches Of podcast, a conversation Gabe recorded in person with Claude Greisler of Armin Strom. Claude is one of the brand's two modern co-founders and its master watchmaker, and he made the trip out to Los Angeles for Open House, where a full spread of the Armin Strom collection was on the tables. Before the watches, the two sat down for a wide-ranging talk about how he got here.
Claude's path is what makes this one worth your time. He grew up in a family of watchmakers, trained for the better part of a decade across Swiss watchmaking, restoration, and movement construction, and cut his teeth on high complications at Christophe Claret. But unlike so many of his peers, he never put his own name on a dial. Instead, with his childhood friend Serge Michel, he took over Armin Strom: a legendary local watchmaker whose vision was a single, clear idea — the movement should be the star of the watch. That conviction is the spine of the conversation, from the decision to become a true in-house manufacturer to the brand's signature complications and its philosophy of transparent mechanics.
This is also, at heart, an Openwork episode. What we keep coming back to on this show is the power of a clear, strong brand identity, and Armin Strom is a near-perfect case study: a watchmaker who walked away from the obvious move to inherit a brand with a reason for being, then re-engineered it from scratch. Along the way, Claude demystifies resonance — what it actually is, and why Armin Strom's approach to it is so distinct — using a couple of analogies that made it click for Gabe, and probably will for you too. We'll be back next week with a regularly scheduled episode.
