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.

What is the exact lug width of the MB&F Legacy Machines 04.TR.BLB?
The lug width of the MB&F Legacy Machines 04.TR.BLB is 20 millimetres. This dimension offers considerable versatility when pairing with artisanal straps. To verify the measurement with precision, use a digital calliper positioned on the internal attachment pins at the widest point of the lugs.
What is the best strap to pair with the MB&F Legacy Machines 04.TR.BLB?
The optimal strap depends on intended usage and aesthetic preference. Natural anthracite alligator amplifies the futuristic character of the titanium case. Vegetable-tanned calf leather offers elegant ageing and patina development over time. A ballistic NATO strap emphasises the engineering DNA of the piece. For summer wear, vulcanised FKM rubber with diagonal grooves provides superior grip and functionality.
How do you change the strap on the MB&F Legacy Machines 04.TR.BLB?
Strap replacement is executed via removable spring bars (attachment pins). Use a spring bar tool to gently compress the internal pin, extracting one end of the strap first, then the other. Position the new strap by aligning the lug holes with the pins, and reinsert the spring bars until they click into place. Verify that the strap is firmly secured before wearing the timepiece.
Which aftermarket straps are compatible with the 04.TR.BLB?
The MB&F Legacy Machines 04.TR.BLB is compatible with any strap featuring a 20mm lug width, regardless of manufacturer. Milano Straps offers a dedicated collection of artisanal straps in this dimension, crafted from noble leathers (alligatore, calf, shell cordovan), technical fabrics (NATO), and synthetic rubbers (FKM). Always verify that the strap possesses adequate thickness for the case's spring bars.
What is the typical lifespan of a leather strap on a daily-wear timepiece?
Durability depends on leather quality, tanning method (vegetable tanning offers superior robustness), climate conditions, and frequency of use. A calf or alligator strap with vegetable tanning, worn daily, maintains excellent resistance for 4-7 years. Natural ageing of the leather is desirable: the patina developed through time confers character and authenticity. Constant exposure to humidity, chlorine, or marine salt reduces longevity. Regular maintenance with specialist creams extends strap lifespan considerably.
