Frequently asked questions

What is the lug width of the Mido Multifort M038.431.37.051.00?

The lug width of the Mido Multifort M038.431.37.051.00 is 22mm. This measurement represents the distance between the attachment pins on the case. To verify, simply remove the original strap and measure the space between the two fixing points on the lugs. At 22mm, this is a very common measurement in the artisanal strap market, ensuring a wide selection of materials and finishes.

Which strap is most suitable for the Mido Multifort M038.431.37.051.00?

The Multifort pairs exceptionally well with vegetable-tanned leather straps (for daily use with ageing patina), alligator (for semiformal occasions), NATO canvas Cordura (for tactical and sporting applications), and rubber (for maximum water resistance and minimal maintenance). The choice depends on context: Tuscan leather is ideal for those seeking character that improves over time, alligator for discreet formality, NATO for tactical versatility.

How do I change the strap on the Mido Multifort M038.431.37.051.00?

Two fundamental operations are required: removal of the spring bars (using a dedicated tool, the strap removal tool, which applies light lateral pressure) and insertion of the spring bars into the new strap, aligning them perfectly with the lateral holes. The procedure takes only seconds. If your Multifort has a deployante clasp, this must be detached from the original strap before proceeding with spring bar removal.

Which aftermarket strap is compatible with the Mido Multifort M038.431.37.051.00?

Any strap manufactured with a 22mm lug width is perfectly compatible. Compatibility is guaranteed by lug width: for the Multifort, always seek straps specifically labelled as 22mm. Available from Milano Straps in full-grain vegetable-tanned leather, alligator, shell cordovan, premium NATO, and structured rubber, all with identical lug specifications.

How long does a leather strap last on the Mido Multifort M038.431.37.051.00?

A quality leather strap, used daily and subjected to ordinary maintenance (occasional cleaning, air-drying after moisture exposure), guarantees a lifespan of 5-8 years before the structure begins to yield. Tuscan vegetable tanning, in particular, ages beautifully: the patina that forms over time is not a defect but a sought-after aesthetic characteristic. Rubber straps last considerably longer (10+ years) as the material is not subject to biological deterioration.
