The Legacy Machines 06.TAL.BLG, seen from the bench

The MB&F Legacy Machines 06.TAL.BLG is a 44mm tantalum case watch featuring the exclusive MB&F LM Thunderdome caliber with vertical tourbillon movement. The 20mm lug width accommodates standard watch straps and reflects MB&F's philosophy of three-dimensional horological design. This model combines tantalum's corrosion-resistant properties with a transparent case back that displays the mechanical movement as a central narrative element.

Frequently asked questions

What is the exact lug width of the MB&F Legacy Machines 06.TAL.BLG?

The MB&F Legacy Machines 06.TAL.BLG is fitted with a lug width of 20 millimetres. This lug width measurement refers to the distance between the internal pins of the case lugs and determines compatibility with any aftermarket strap. To verify, use a digital calliper positioned perpendicularly between the two case lugs.

Which strap material is most suitable for the Legacy Machines 06.TAL.BLG?

For the 06.TAL.BLG, we recommend an alligator leather strap with vegetable tanning, in cognac brown or black. Alligator offers refined grain that contrasts elegantly with the case's tantalum. Alternatively, vegetable-tanned calf leather with aged patina creates sublime aesthetic harmony, whilst NATO or NBR rubber ensures practicality without visual compromise.

How do I change the strap on my Legacy Machines 06.TAL.BLG?

Extract the spring bars using a dedicated spring bar removal tool. Position the tool in the groove of one pin and lift gently until the end is freed. Repeat for the opposite side. Insert the pins into the new strap, aligning internal holes, then reinsert the pins into the case lugs. Ensure the strap is centred on the case.

Which aftermarket straps are compatible with this model?

All straps with a 20mm lug width are compatible with the 06.TAL.BLG. Milano Straps offers a dedicated collection of 20mm straps in alligator leather, vegetable-tanned calf, NATO, and rubber. Always verify that the deployante clasp is appropriately sized for the case diameter (44mm) for optimal fit and proportional aesthetics.

What is the average lifespan of a leather strap for the Legacy Machines 06.TAL.BLG?

A quality leather strap (alligator or vegetable-tanned calf) develops natural patina after 12–18 months of regular wear. Effective durability varies based on wearing frequency and climatic conditions. With periodic maintenance (microfibre cloth cleaning, annual hydration), a leather strap can remain aesthetically sound for 3–5 years before replacement. Rubber straps have similar lifespan but do not develop patina.
