Frequently asked questions

What is the lug width of the Mido Commander M021.431.22.071.00?

The Mido Commander M021.431.22.071.00 features a 21mm <a href="/pages/termine-glossario/misura-ansa">lug width</a>. This measurement is standardised on this model and requires straps specifically cut for this width. Always verify the exact reference before purchasing an aftermarket strap.

Which strap material pairs best with the Mido Commander?

For the Commander M021.431.22.071.00, we recommend calf leather or <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> for refined everyday wear, or <a href="/pages/termine-glossario/alligatore">alligator</a> for a more sophisticated aesthetic. FKM rubber remains the ideal choice for aquatic or sports environments, maintaining grip against the wrist thanks to its textured surface.

How do I change the strap on the Mido Commander M021.431.22.071.00?

Strap removal is performed using a dedicated punch tool to release the spring bars. Position your watch with the inner face upwards, apply gentle vertical pressure on the spring and remove the old strap. Insert the spring bars into the new 21mm strap until they click into place. If you lack experience, consult a professional watchmaker.

Can the Mido Commander M021.431.22.071.00 accept a strap with a <a href="/pages/termine-glossario/deployante">deployant clasp</a>?

Yes, it is possible to mount a strap with a <a href="/pages/termine-glossario/deployante">deployant clasp</a> (safety fold-over buckle) on this model. The <a href="/pages/termine-glossario/deployante">deployant clasp</a> offers superior wrist comfort and a more secure closure compared to a traditional buckle. Ensure the strap width is precisely 21mm at the lugs.

How long does a leather strap last on a Mido Commander?

The lifespan of a <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned leather</a> strap ranges from 2 to 5 years with daily use and proper care. Factors such as humidity, perspiration and sun exposure accelerate ageing. A shell cordovan strap, thanks to its denser structure, can exceed 7–8 years. Regular maintenance with natural oils significantly extends its longevity.
