FAQ
What is the lug width of the Mido Commander M031.631.11.031.00?
The lug width of the Mido Commander M031.631.11.031.00 is 21mm, a non-standard measurement that requires a conscious choice of strap. To verify strap compatibility, measure the distance between the two case lugs with a digital calliper: the distance must be exactly 21.00mm for a perfect fit without tension or play.
What is the best strap for the Mido Commander M031.631.11.031.00?
The best strap depends on use and personal preference. For a formal look, we recommend an alligator or vegetable-tanned calf strap in dark brown tones. For sports use, a NATO strap in ballistic fabric maintains the watch's operational vocation. For aquatic environments or intensive work, a rubber or fluoroelastomer strap offers practicality without aesthetic compromise. All straps must respect the 21mm lug width.
How do I change the strap on my Mido Commander M031.631.11.031.00?
Changing the strap requires specific tools: a spring bar tool and a stable work surface. Position the watch with the lug facing upwards, insert the screwdriver of the spring bar tool into the spring groove to release it, remove the old strap and insert the new one respecting the orientation. Ensure the springs are properly locked before wearing the watch. If you are not experienced, consult a qualified watchmaker.
Can I use a generic aftermarket strap on my Mido Commander M031.631.11.031.00?
No, a generic strap may not be compatible. The Mido Commander M031.631.11.031.00 requires a strap with exactly 21mm lug width. Standard 20mm or 22mm straps will create play or excessive tension. Contact specialist suppliers that guarantee straps built for this specific measurement, such as the 21mm compatible straps.
How long does a leather strap last on a watch like the Mido Commander M031.631.11.031.00?
Longevity depends on leather quality, frequency of use and exposure to atmospheric agents. A good quality alligator or vegetable-tanned calf strap typically lasts 3-5 years with daily use, developing a natural patina and character over time. Frequent exposure to sweat, water and UV rays shortens durability. Regular maintenance (hydration with specific creams, drying after water contact) significantly extends strap life. Rubber straps have greater durability but suffer hardening over time.
