Multifort M038.431.11.041.00— lug 22mm

The lug width of the Mido Multifort M038.431.11.041.00 is precisely 22 millimetres. This measurement is critical when selecting an aftermarket strap: it must match exactly to ensure proper insertion into the case lugs without forcing or excessive play.

The ideal strap depends on intended use and context. For formal wear, we recommend alligator leather or vegetable-tanned calf, which enhance the case's rationalist design. For everyday versatility, a NATO in dark grey or black canvas offers solidity and practicality. For humid and demanding environments, FKM (Viton) rubber provides maximum resistance and grip.

Obtain a dedicated spring bar tool or consult a watchmaker. Position the watch face down, locate the small pin (spring bar) securing the strap to the lug. Press the pin downward to release the old strap from the lug, then insert the new 22mm strap by aligning the lug correctly in the spring bar groove. The pin will lock automatically under spring tension.

Any strap with a 22-millimetre lug width is compatible. On milanostraps.it you will find a broad range: Tuscan leather, shell cordovan, alligator, calf, NATO canvas, and FKM rubber. Ensure the lug width is precisely 22mm: even a fraction of a millimetre variance will compromise fitting.

A natural leather strap with vegetable tanning, subject to moderate daily use, typically lasts 3–5 years before showing structural wear. Longevity depends on exposure to perspiration, humidity and UV rays. A strap developing a controlled patina may last 7–8 years. FKM rubber resists longer (8–10 years) but ages aesthetically more rapidly.
