Made to Measure

The strap for this watch is made to measure

On the MB&F Horological Machines the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a strap be fitted to an MB&F Horological Machines 56.STGL.B?

The lug system of the 56.STGL.B is integral to the case design and does not accept standard straps. However, a bespoke strap can be constructed and fitted with precision to the specific proportions of your watch. This exclusive service is provided by <a href="/pages/casati-booking">Casati Milano</a>, which measures the watch directly and creates the custom strap.

How does the bespoke strap creation process work for this model?

The artisan at Casati Milano measures your watch in their atelier to understand the exact lug dimensions and case geometry. Based on this survey and your wrist circumference, the strap is hand-crafted and tested directly on your timepiece. This is not an adaptation, but a complete creation tailored to this specific watch.

Which leather suits the character of the MB&F Horological Machines 56.STGL.B?

Vegetable-tanned leathers with pronounced grain and deep patina respect the structural authority of the titanium and steel case. Colours such as deep brown, natural grey-green, or aged black amplify the visionary character of the watch without distracting from its pure geometry. Avoid overly fine or ornate leathers, which would clash with the architectural brutality of the case.

How long does a well-made strap last on a watch of this calibre?

An artisanal strap crafted from superior leathers and constructed with bespoke methodology endures for decades with proper care. Leather ages gracefully, developing a patina that enriches the aesthetic value of your watch. With minimal maintenance—occasional cleaning and seasonal conditioning—the strap becomes part of your timepiece's personal history.

Why does the 2015 MB&F Horological Machines 56.STGL.B remain an absolute reference in contemporary high watchmaking?

The 56.STGL.B represents the pinnacle of Maximilian Büsser's creative vision in pursuing sculpture-watches. The HMX calibre with jumping hours is an exceptionally rare construction where mechanical complexity remains featherweight and entirely visible. The simultaneous use of titanium and steel creates a chromatic stratification that ages naturally, transforming the watch over decades. It is not simply a timepiece, but an object that challenges the very definition of wearable accessory.
