The Heritage
The strap for this watch is made to measure
On the MB&F Legacy 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.

Can a standard strap be mounted on the MB&F Legacy Machines 04.RL.W4?
No, not a standard one. The case lug is proprietary and integral to the design. A generic strap will not fit properly. However, a solution exists: <a href="/pages/casati-booking">Casati Milano</a> crafts fully bespoke straps by measuring the exact dimensions of your watch's attachment points and creating a custom strap that integrates seamlessly with the case.
How does the bespoke strap construction process work for this model?
The process begins with a consultation at the atelier, where <a href="/pages/casati-booking">Casati Milano</a> craftsmen take precise measurements of your watch's proprietary lug. Using these specifications, they design a personalised strap, work with you to select the leather, and hand-craft the final piece. Each strap is unique, created exclusively for your timepiece.
Which leather suits the character of the MB&F Legacy Machines 04.RL.W4?
Natural vegetable-tanned leathers with deep patina: aged crocodile, black alligator with tight grain, vintage calf. These materials share the essential quality of the rose gold case and develop unique character over time, creating a visual dialogue between the cold precision of the metal and the warm imperfection of leather.
How long does a well-crafted artisanal strap last?
A strap made from quality vegetable-tanned leather, built on your watch, and maintained with ordinary care, lasts for years. The leather ages beautifully, developing character while the structural integrity remains intact. If needed, the craftsmen at <a href="/pages/casati-booking">Casati Milano</a> can perform maintenance and repairs to extend the strap's lifespan further.
Why is the Legacy Machine 04.RL.W4 so radical in its design approach?
Maximilian Büsser rejected tradition entirely: the movement is not hidden but displayed as visible architecture. Suspended balance wheels, hand-finished bridges, every constructive element becomes part of the aesthetics. The rose gold case from 2020 amplifies this philosophy, transforming the watch into a mechanical sculpture that engages with contemporary avant-garde, not with the past.
