Strap for Excellence Le Régulateur Louis Erard x Massena LAB Gold

The lug width is 22 millimetres. This measurement defines the distance between the two fixing pins located at the extremities of the case, and is determinant for the compatibility of any aftermarket strap. A 22mm strap will insert into the case with precise fit, avoiding lateral play that would compromise aesthetics and security.

The choice depends on context of use. For formal and professional environments, an alligator or quality calf leather strap ensures elegance and patina that will improve over time. For a versatile daily approach, a robust NATO or technical rubber strap offers practicality without sacrificing the aesthetic identity of the timepiece. Ideally, owning two straps allows one to interpret the same watch in vastly different contexts.

Use a spring bar tool – a specific metal instrument with two ends: one thin and curved to lift the pin, one forked to retain it. Position the timepiece on a stable surface, illuminate the lateral area of the case, introduce the curved tip of the tool into the internal groove of the lug to lift the pin, and simultaneously apply pressure with the fork to retain it. Extract the pin completely, remove the old strap, insert the pin into the new strap aligning the holes, and press until a click of anchorage. Repeat on the opposite side.

Yes, provided that the measurement is precise. Compatibility depends exclusively on lug width (22mm) and the quality of strap workmanship. Straps available through Milano Straps have been verified for fit and aesthetic proportion with the Louis Erard Excellence, ensuring optimal fitting without lateral play or forcing.

A quality leather strap, subjected to vegetable tanning, has an average lifespan of 3-5 years with daily use, considering exposure to perspiration, humidity and thermal fluctuations. This estimate varies based on frequency of use, climate, and care applied (avoid water, allow to dry if exposed to humidity, store away from excessive heat). An alligator strap tends to last slightly longer than calf, owing to the more robust structure of the leather.
