Ultra-Chron Classic
A dress watch with a sophisticated character, this model balances clean lines and practical features. The automatic movement is complemented by a classic date function, making it a refined choice for any occasion.
Between the 37mm Classic and the 43mm sport version sits this 40mm reference, ref. L29374722 — same silver dial, leather strap, date window, and 50m water resistance as its smaller sibling, just 3mm more presence on the wrist. That gap matters more than it sounds: 37mm reads distinctly vintage-correct, while 40mm is the size most buyers today actually reach for when they want vintage proportions without feeling undersized next to a modern wardrobe. Same manufacture high-frequency movement underneath either way, so the choice between the two really comes down to how your wrist and your eye respond to that 3mm, nothing else.
