FAQ

What is the lug width of the Mido Commander M031.631.11.061.00?

The lug width of the Mido Commander M031.631.11.061.00 is 21mm. This measurement defines the distance between the two metal pins (spring bars) on the case where the strap is attached. It is essential to respect this exact width to avoid compatibility issues and ensure proper installation.

Which strap is most suitable for the Mido Commander M031.631.11.061.00?

For the Commander M031.631.11.061.00, we recommend straps in alligator or vegetable-tanned leather for an elegant and durable aesthetic. If you seek versatility, NATO straps in cordura offer daily practicality. For sports contexts or adverse weather, vulcanised rubber is the optimal solution. All materials must feature 21mm lug width.

How do I change the strap on my Mido Commander watch?

Changing the Commander's strap requires a dedicated tool (spring bar or extraction tool). Position the watch on a stable surface, locate the pins at the ends of the lug and apply gentle pressure with the tool to release the spring. Once the old strap is removed, insert the new one by correctly aligning the spaces with the pins. Professional watchmaker intervention is recommended to avoid accidental damage.

Can I fit an aftermarket strap on my Mido Commander M031.631.11.061.00?

Yes, any strap with 21mm lug width is compatible with the Commander M031.631.11.061.00. Artisanal straps allow superior personalisation in terms of materials (alligator, shell cordovan, calf leather), finishes and colours. Ensure the strap is correctly sized and that the pins are installed securely.

How long does a leather strap last on a daily-wear watch?

The durability of a leather strap depends on the material and maintenance. An alligator or vegetable-tanned calf strap can last 3-5 years with daily wear if properly maintained (occasional cleaning, avoiding prolonged moisture). Leather naturally thins and develops a patina; when the strap shows structural wear signs, replacement is advised to preserve the watch's integrity.
