Strap for Horological Machine N°3 HM3 Megawind White Gold

No, the bracelet is integrated into the case and uses a proprietary attachment — a standard strap won't fit. For this model I work differently: I build a bespoke strap directly in the atelier, crafting the specific attachment directly onto your case.

You meet me at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, study the attachment architecture and hand-build the strap. It's pure craft, nothing standardised.

I favour Mississippi Alligator in black, or fumé Barenia. These leathers have the structure and nobility that a case like this deserves — black speaks cleanly with titanium, fumé brings warmth beside white gold. They age with character.

With a properly crafted strap, between four and seven years of daily wear. It depends how you treat it: avoid water, protect it from direct sun, clean it with a soft cloth. Leather ages and develops patina — that's part of its beauty, not a flaw.

To protect the design's radicality. The HM3 FrogX is an orbital sculpture — by integrating the bracelet, MB&F prevented anyone from 'normalising' it with a generic strap. It's an act of design coherence, very MB&F.
