Strap for Multifort Powerwind Stainless Steel / Grey / Bracelet

The lug width of the Mido Multifort M040.407.11.031.00 is 19 millimetres. This measurement refers to the internal distance between the two spring bars that secure the strap to the case. To verify compatibility with a new strap, measure internally using a millimetre ruler: exactly 19mm is the required value. Do not confuse this with the case diameter (40mm) or the strap thickness.

The choice depends on primary use and aesthetic preferences. For mixed use (office and leisure), a vegetable-tanned calf leather or alligator strap provides elegance and durability. For sporting or work use, a NATO strap in cordura or a FKM rubber sports strap ensures resistance and quick-change capability. For formal settings, grey or taupe alligator, or dark brown calf, pairs perfectly with the stainless steel case. Shell cordovan in warm reddish-brown represents a refined and historically relevant choice.

Strap replacement is performed via the spring bars (pins) located at the case extremities. Use a spring bar tool or small flat screwdriver to gently push the pin inward, allowing the existing strap to slide out from the lugs. Insert the new strap ensuring both pins are engaged and the strap is aligned symmetrically. For straps with deployante clasps, verify that the closing mechanism functions before wear. We recommend performing this operation on a soft surface to prevent scratches.

Yes, numerous aftermarket 19mm straps are compatible with the M040.407.11.031.00. MilanoStraps.it offers handcrafted leather straps (calf, alligator, shell cordovan), NATO straps in textile, and sports rubber straps. All 19mm straps are dimensionally suitable; selection centres on material, colour, strap thickness, and closure type (standard, deployante, adjustable buckle). Handcrafted straps allow customisation of colour, stitching, and finishing to match personal aesthetic preferences.

The lifespan of a leather strap depends on material type, tanning method, and daily use. A vegetable-tanned calf strap, worn regularly (4–5 days weekly), maintains structural integrity for 3–5 years. An alligator strap, being denser leather, may last 4–6 years. Shell cordovan, renowned for longevity, can exceed 6–7 years. Natural wear includes small creases at flex points, finish fading, and loosening of attachment stitching. Regular maintenance (cleaning with a damp cloth, periodic conditioning) significantly extends lifespan.
