Mido
Baroncelli M037.407.11.041.00— lug 20mm

The lug width (ansa) of the Mido Baroncelli M037.407.11.041.00 is 20mm. This measurement corresponds to the distance between the two spring bars integrated into the case. Verify it by measuring directly on the case surface between the metal pins.

For this model with sunburst blue dial, we recommend a vegetable-tanned leather strap in cognac or dark brown, which creates aesthetic synergy with the dial tone. Alternatively, Mississippi alligator in medium brown or black, or a NATO strap in technical navy fabric. All must have 20mm lug width.

Use a spring bar tool (thin lever instrument) to gently compress the spring bars from both sides simultaneously, creating space to extract the old strap. Insert the new 20mm strap ensuring both pins position correctly in the holes. Slowly release pressure to secure the spring bar.

Yes, any quality strap with 20mm lug width is compatible with the M037.407.11.041.00. Verify that the strap pins fit correctly into the case holes: they must enter firmly without lateral movement. Avoid low-quality straps that could damage the case spring bars.

A quality vegetable-tanned leather strap, worn daily, lasts approximately 3-4 years before requiring replacement, developing a natural patina that enhances character. Lifespan depends on sun exposure, humidity, and frequency of wear. Alligator has superior longevity, 5-7 years. Rubber is virtually unlimited if kept clean.
