The Horological Machines 36.SVL.GR, seen from the bench

The MB&F Horological Machine HM3 features the in-house HM3 caliber with hours, minutes, day/night indication, date and power reserve display. The movement is characterized by a three-dimensional architecture with vertical displays for time reading. The reference 36.SVL.GR is part of the Horological Machines collection of the Swiss brand founded in 2005.

Frequently asked questions

Can a watch strap be fitted to the MB&F Horological Machines 36.SVL.GR?

The lug attachment of the 36.SVL.GR does not follow industrial standards: the case integrates a proprietary system that requires a bespoke solution. A conventional watch strap is not compatible, but an artisanal alternative exists and is the only approach that respects the original design intention. <a href="/pages/casati-booking">Casati Milano</a> crafts personalised straps adapted specifically to this model.

How does the bespoke strap construction process work for the Horological Machines?

The artisan at Casati Milano performs a direct survey of the case, tracing the exact measurements of the proprietary attachment points. Subsequently, the strap is constructed in the workshop, ensuring that width, angle, and proportions remain coherent with the watch's original design. Every element—from lug to passant to buckle—is calibrated for this specific timepiece, creating total integration.

Which leather type suits the character of the MB&F Horological Machines 36.SVL.GR?

The 36.SVL.GR, being a transparent machine celebrating technical precision, harmonises with structured leathers such as crocodile and alligator, whose geometric textures dialogue with the complexity of visible mechanisms. Alternatively, vintage leathers with natural patina create a compelling contrast between the perfection of the sapphire case and the noble imperfection of aged hide. Modern technical materials also find aesthetic coherence with this radical vision of horology.

How long does a well-crafted artisanal watch strap last?

A strap made from quality leather by a competent artisan, with proper maintenance, maintains structural integrity for several years. Durability depends on the leather chosen (superior crocodile lasts longer), daily versus occasional wear, and proper care: periodic cleaning and targeted conditioning extend useful life. The patina developing over time increases the narrative value of the strap, making it progressively more personal.

What makes the HM3 movement in the 36.SVL.GR so different from other calibres?

The MB&F HM3 calibre does not organise components on a single plane but develops them vertically, creating a three-dimensional architecture visible through the sapphire case. This constructive approach allows integration of hours, minutes, day, night indication, date, and power reserve in a composition that challenges classical horology standards. It is a machine demanding observation from every angle, never hidden beneath the wrist.
