Strap for Robert Mühle Kleine Sekunde

The lug width of the Mühle Glashütte Robert Mühle M1-11-05-LB is 22 millimetres. This measurement is standard for the model and is compatible with all straps in the 22mm collection available on Milano Straps. To verify correct measurement, use a digital calliper and measure the distance between the lugs on the case.

For the M1-11-05-LB, we recommend a Tuscan vegetable-tanned leather strap (Havana or Bordeaux) to enhance formal aesthetics, or a matt black alligator strap to emphasise the instrumental character. If you prefer versatility, a NATO strap in grey or dark blue remains the most versatile choice for this timepiece. Selection depends on use: formal wear calls for leather or alligator, whilst daily-technical use points towards NATO or FKM rubber.

Strap replacement is straightforward: use a spring bar tool to gently compress the pin and separate the old strap from the case. The new 22mm strap is inserted by aligning the holes with the pins and releasing the tool. Never force the pins to avoid damage to the lugs. If you are inexperienced, we recommend consulting a watchmaker or servicing specialist.

Yes, an aftermarket 22mm strap is perfectly compatible. Milano Straps offers artisan-crafted straps in leather, NATO and rubber, all tested on this lug width. The superior quality of materials (vegetable-tanned leather, alligator, military canvas) often exceeds the factory strap, allowing you to personalise the timepiece whilst maintaining elevated construction standards.

A quality leather strap (vegetable-tanned or shell cordovan) typically lasts 2-4 years with daily use, up to 7-8 years with occasional wear. Longevity depends on exposure to water, perspiration and sunlight. Vegetable-tanned leather develops a natural patina over time, making the strap more characterful. A NATO strap lasts longer (5-10 years), whilst FKM rubber resists for 3-5 years before requiring replacement.
