Frequently asked questions

What is the lug width of the MB&F Legacy Machines 04.RL.W2?

The lug width of the MB&F Legacy Machines 04.RL.W2 is 20 millimetres. This technical parameter determines strap compatibility: it is the linear distance between the two attachment lugs situated on the case. A 20mm strap ensures proper installation and aesthetic proportion relative to the 44-millimetre case diameter.

Which strap is best suited for the MB&F 04.RL.W2 in red gold?

For the red gold 04.RL.W2, we recommend an alligator strap in mahogany tone or vegetable-tanned calf in dark brown hues. These materials create aesthetic synergy with the warm case colour, favouring harmonious ageing over time. Valid alternatives include cognac-coloured shell cordovan or pure black for more formal effects. NATO and rubber options offer sportier versatility.

How do I change the strap on the MB&F Legacy Machines 04.RL.W2?

To change the strap, use a spring bar tool or dedicated implement to extract the pins (spring bars) from the case lugs. Proceed gently to avoid damaging the case: position the tool beneath the pin, apply light pressure, and slide the pin out of its seat. Repeat for the second pin. Install the new strap in reverse order. For watches of the 04.RL.W2's value, professional servicing is recommended.

Can I use aftermarket straps compatible with the MB&F Legacy Machines 04.RL.W2?

Yes, aftermarket straps are compatible provided they meet the 20-millimetre lug width specification. Quality artisanal straps allow you to personalise the watch whilst maintaining mechanical and aesthetic compatibility. We recommend verifying that the strap is crafted from noble materials and precise workmanship to avoid compromising the value and aesthetics of a mechanical work such as the 04.RL.W2. Milano Straps curates a selection of 20mm straps specifically designed for this purpose.

How long does a leather strap last on the MB&F 04.RL.W2?

A quality leather strap, crafted in alligator or vegetable-tanned calf, has an average lifespan of 3-5 years with daily use and proper maintenance. Longevity depends on exposure to moisture, perspiration, and mechanical stress. A shell cordovan strap, thanks to its superior structural density, can last 7-10 years. The patina and marks that accumulate do not represent deterioration but rather the natural evolution of leather, which enhances the character and aesthetic value of the pairing with the 04.RL.W2's red gold.
