Strap for Senator Diary Red Gold / Silver / Alligator / Folding

The lug width of the Senator 100-13-01-01-50 is 20 mm. This measurement refers to the internal distance between the two terminal bars of the case. It is essential to verify this compatibility before purchasing an aftermarket strap, as an incompatible lug width generates mechanical stress and compromises both the aesthetics and longevity of the strap.

For the Senator 100-13-01-01-50 in 5N rose gold, we recommend an alligator strap in vegetable tanning in dark brown or cordovan tones. These materials naturally resonate with the warmth of rose gold and develop a patina over time that enriches the timepiece. Alternatively, a seasoned shell cordovan offers density and luminosity comparable to metal, creating a dialogue of great refinement.

The strap is changed by removing the current one using a spring bar tool. Locate the two lateral passants of the case, insert the tool under the terminal of the lug to release the tension of the internal spring, then extract the lug from the holes in the case. Repeat the operation on the opposite side. Proceed in reverse to install the new 20 mm strap. If you are not experienced, consult a trusted watchmaker or Atelier Casati Milano.

Yes, provided the strap is constructed for a 20 mm lug width. Milano Straps artisan straps are handmade to this specification, guaranteeing complete compatibility and proportions consistent with the original design of the Senator. It is advisable to choose straps where the curvature of the lug reflects the geometry of the integrated case, to avoid mechanical play.

A high-quality natural leather strap, such as those made by Milano Straps, has an estimated lifespan of between 3 and 7 years of daily use, depending on the material (cordovan is more resistant than calf), frequency of use, and maintenance. Alligator in vegetable tanning tends to last longer due to the density of the leather. Periodic cleaning and occasional application of balm preserve flexibility and slow ageing.
