The Multifort M040.407.11.091.00, seen from the bench

It features the ETA caliber C07.621 automatic movement with 21 jewels and chronometer precision, housed in a 10.5mm case with transparent caseback. The white dial with rose gold applied indices includes date and day windows at 3 o'clock, offering 100 metres water resistance. The 316L stainless steel ensures natural patina development. Lug width is 19mm.

Frequently asked questions

What is the lug width of the Mido Multifort M040.407.11.091.00?

The Mido Multifort M040.407.11.091.00 features precisely 19mm lug width. This measurement must be verified using a digital calliper, measuring from the inner base of one lug to the inner base of the other. Do not substitute 20mm variants, as they introduce structural stress on the case and compromise the aesthetic proportions.

Which strap material is recommended for the Mido Multifort M040.407.11.091.00?

For the Multifort, we recommend three directions: premium leather (alligator or vegetable-tanned calf, in dark tones such as chocolate brown or rum), NATO in heavy cotton (grey, blue, black), or FKM rubber for water resistance. Selection depends on context—formal, daily wear, or sports—and the rose-gold tone of the dial numerals.

How do I change the strap on the Mido Multifort M040.407.11.091.00?

The Multifort uses standard removable spring bars. Position the watch in a watch holder, extract one spring bar from opposing sides using a dedicated spring bar tool, and replace it with the new strap. A straightforward operation requiring just minutes and no advanced technical skill. If uncertain, consult a certified watchmaker.

Can I fit an aftermarket strap on this model?

Yes. The M040.407.11.091.00 accepts any 19mm strap with standard spring bars, so aftermarket compatibility is complete. Ensure only that the lug width is certified at 19.0mm ± 0.5mm, and that strap thickness does not exceed 4-5mm in the lug keeper zone.

What is the lifespan of a leather strap on this watch?

A high-quality leather strap, vegetable-tanned and well-maintained, offers a lifespan of 2-4 years with moderate daily use. Longevity depends on exposure to humidity, perspiration, and UV rays. Rubber and NATO extend this window to 4-6 years, being materials less sensitive to environmental ageing.
