Strap for Ingenieur Automatic Red Gold / Slate

No, the bracelet is integrated into the case — there's no standard lug where you'd thread a strap. The monobloc architecture is intentional: the transition between steel and leather must be built specifically for your watch. I create the strap directly on your case, millimetre by millimetre.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your case — I feel the original lugs with my hands, study their geometry with industrial precision calipers. It's the only way to build a transition that honours the Ingenieur.

Barenia. It has the sporty yet refined character this watch demands — it darkens over time like the satin-finished steel case, creating a patina that tells the story of years worn. It's leather that ages with dignity, exactly what an Ingenieur needs on your wrist.

With a strap built properly, 7–10 years of daily wear without issue. Noble leather demands respect: don't leave it in direct sun for weeks, don't soak it carelessly. Treat it that way, and you'll watch it improve year after year.

It was born in the 1950s as an engineer's watch — it protected the movement from magnetic fields that damage mechanisms. That Faraday cage, that monobloc solidity, solved a real problem. Today that's not necessary anymore, but the aesthetic choice remains: architecture that refuses compromise.
