Mido
Multifort M040.407.11.041.00— lug 19mm

The lug width of the Mido Multifort M040.407.11.041.00 is 19 mm, a rare measurement that requires specific straps. To verify it, measure with calliper the distance between the internal contact points of the upper lug at the case. This specificity makes the model exclusive and requires careful attention when selecting aftermarket options.

The best strap depends on your lifestyle. For formal settings, a satin-finished alligator or vegetable-tanned calf leather creates aesthetic harmony with the brushed steel case. For a more sporty look, a well-made NATO or technical rubber strap maintains the model's functional sobriety. The key is that the strap has a certified 19 mm lug width.

Strap replacement requires a specific tool: a spring bar removal tool. Insert the curved end of the tool under the lower lug pin, gently compress the internal spring until the pin clicks free, then extract the worn strap. Position the new strap by aligning the holes and reintroduce the pin until it locks with an audible click. If unsure, entrust the operation to a specialist watchmaker to avoid case damage.

Any strap with a 19 mm lug width is compatible. We recommend verifying the actual width directly from the supplier. Straps in alligator, calf, shell cordovan, NATO, and rubber are all appropriate, provided they respect the 19 mm gauge. Many quality brands offer online customisation, adjusting the length to your specific wrist size.

A high-quality leather strap (alligator or calf) has an average lifespan of 3–5 years with moderate daily use. Leather fibres gradually break down through friction with skin, lug movement, and humidity exposure. Keeping the strap dry and occasionally applying protective wax extends its life. A NATO or rubber strap, being less subject to biological degradation, can last 7–10 years or more.
