Strap for Horological Machine N°3 HM3 Ti Frog

No, not a standard one: the attachment is an integral part of the case's architectural design. However, it is possible to have a bespoke strap built entirely to measure on the watch through <a href="/pages/casati-booking">Casati Milano</a>'s bespoke service. This is not an adaptation, but a made-to-order sartorial creation.

The process begins with a precise metric survey at Casati Milano's atelier, where every angle and construction variable of the 32.TL.B is recorded. Next, a personalized technical drawing is created and the strap is constructed directly on the watch, ensuring perfect geometric cohesion between case and strap.

The radical design of the 32.TL.B requires leathers with marked texture and visible grain—alligator, Nile crocodile, or vegetable-tanned hides with natural patina. Smooth leathers with satin or subtle embossed finishes also work well. Ideal colours are black, titanium grey, or dark brown with natural undertones, which amplify dimensionality without competing with the case's sculpture.

A strap made with sartorial techniques and superior quality leathers, as those used by Casati Milano, lasts for years with routine care—periodic cleaning, natural air-drying, occasional conditioning. Longevity depends on use, but the solid construction makes it a durable investment over time.

Because it represents Max Büsser's manifesto: a three-dimensional architecture that defies classical watch conventions. The HM3 calibre visualizes time through an expressionist composition, titanium allows sculpture without weight, and every element—including strap attachments—is conceived as part of a functional work of art, not an ordinary watch.
