Strap for Senator Chronometer White Gold / Silver / Alligator / Folding

The lug width of the Senator 1-58-03-01-04-50 is 21 millimetres. This measurement is essential for selecting a compatible replacement strap and must be measured precisely between the two lateral attachment points of the case, at the exact location where the strap connects to the watch.

For a white gold Senator, black or dark brown alligator represents the finest aesthetic choice, emphasising the luminosity of the case. Calf leather with vegetable tanning offers versatility and develops a natural patina over time. For sports applications, a high-density cotton NATO strap provides practicality whilst maintaining elegance.

The strap is changed by removing the lateral spring bars using a dedicated tool. Position the watch on a soft cushion, locate the small holes at the ends of the lugs, insert the spring bar tool to compress the internal pin and extract it. Insert the new 21mm strap and ensure it is secured firmly before wearing the watch.

A high-quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with moderate daily use, depending on exposure to perspiration, moisture and sunlight. A vegetable-tanned leather strap develops a natural patina and can last longer with regular maintenance. NATO or rubber straps offer greater longevity, lasting up to 7-10 years.
