The Horological Machines 70.PBL.B, seen from the bench

The MB&F HM7 belongs to the Horological Machines collection and features a three-dimensional design with an open-worked movement. The timepiece is equipped with the in-house developed HM7 caliber, featuring a tourbillon escapement and hour-minute indication. The blue titanium case houses the vertically-oriented mechanism, characteristic of the Horological Machines series.

Frequently asked questions

Can you fit a standard strap to the MB&F Horological Machines 70.PBL.B?

No, the bracelet is integrated into the case. There are no standard lugs to attach a conventional strap. I've seen many owners search for workarounds: the only solution that works is bespoke construction directly in the atelier, adapting the strap to the case's geometry.

How does the bespoke strap work for this MB&F Bulldog?

Come to us at <a href="/pages/casati-booking">Casati Milano</a>, by appointment only. I take measurements directly from your case, studying how the leather must adhere to the platinum curves. Every strap is built individually on that specific watch.

Which leather do you recommend for this model?

Mississippi alligator. This watch is sculptural sport, movement and power: the leather must have that structure, that noble rigidity that doesn't give way immediately. Alligator ages beautifully, develops patina over time, stays true to the Bulldog's radical character.

How long does a well-made strap last?

Depends on use. With normal care, 5–7 years. Good leather ages, it doesn't die: it becomes softer, the patina tells its story. If you treat it well—no direct water, occasional gentle cleaning—you'll be surprised how long it stays elegant.

Why does the Bulldog have such a particular shape?

Büsser built the watch around the movements: those mechanisms you see under the crystal are alive, they move, and the case follows that logic. It's not pure aesthetics, it's function becoming form. That platinum sculpture tells exactly what happens inside.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
