Strap for Horological Machine N°11 HM11 Architect Titanium / Red Gold

No, the bracelet is integrated into the case—there are no standard lug attachments for an off-the-shelf strap. I've seen too many wrong attempts. For this watch, I craft a custom strap directly in the atelier, shaped to the specific geometry of the titanium case.

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from the case, study the angles, and build the strap by hand because every detail must speak to the watch's architecture. There's no rush, only precision.

I favour Italian bruised leather or natural Barenia. This watch is audacious, geometric, sporty in character—it needs a leather that ages with personality, not that fades. The leather must support the design's radicalism without competing with it.

If it's built properly and cared for, at least 5–7 years. The best leather isn't the one that resists time unchanged; it's the one that patinas, that tells a story. I recommend cleaning the strap occasionally, protecting it from salt water and driving rain. Natural ageing is part of the agreement.

Maximilian Büsser designed the HM11 with precise three-dimensional vision: suspended bridges, impossible angles. A generic strap would twist this coherence. I build it millimetre by millimetre in dialogue with the case, respecting the avant-garde without betraying it.
