FAQ
What is the lug width of the Mido Commander M031.631.21.031.00?
The lug width of the Mido Commander M031.631.21.031.00 is 21mm. This measurement is taken between the two metal lugs protruding from the watch case. It is a non-standard width in mass-market offerings, which is why we recommend handcrafted straps to ensure quality and precise workmanship.
Which strap is best suited for the Mido Commander M031.631.21.031.00?
We recommend a high-quality leather strap with vegetable tanning or alligator leather, as it responds to the watch's professional heritage whilst maintaining sober elegance. If you use the Commander in dynamic working environments, a NATO or FKM rubber strap offers practicality and breathability. The choice depends on your use: formal contexts suggest aged leather, sporty contexts suggest fabric or rubber.
How do I change the strap on the Mido Commander M031.631.21.031.00?
Remove the steel lugs using a dedicated spring bar removal tool, available from Casati Milano. Extract the lug from the first lug hole, then from the other. Insert the new strap through both lug holes, ensuring alignment, and reinsert the lugs with firm, even pressure. If you lack experience, we recommend our strap change service at the atelier.
Are 21mm straps compatible with other watches?
Yes, any watch with a 21mm lug width accepts these straps. Consult your watch's technical specifications to verify the exact lug width. Mido Commander, certain Tissot collections, Seiko models and other Swiss brands use 21mm lug width. Contact us to verify compatibility with your specific model.
How long does an artisanal leather strap last on the Mido Commander?
A high-quality leather strap with vegetable tanning or alligator leather lasts 3–5 years with daily wear, depending on sun exposure, water contact and cleaning frequency. The patina that develops is a sign of authenticity. We recommend periodic cleaning with a damp cloth and annual maintenance at Casati Milano to extend the strap's lifespan.
