Strap for Senator Perpetual Calendar Stainless Steel / Silver / Synthetic - Folding

The lug width (ansa width) of the Glashütte Original Senator 1-36-02-01-02-66 is 18 mm. This measurement corresponds to the distance between the internal shoulders of the watch case lugs. A compatible strap must have a nominal width of 18 mm at the attachment point to ensure correct insertion and fit without force.

The ideal strap for the Senator 1-36-02-01-02-66 depends on the occasion. For formal contexts, an alligator leather tanned with vegetable tanning in dark brown or black tones provides sober elegance and develops natural patina over time. Shell cordovan represents the most refined alternative for those seeking structural compactness and intrinsic lustre. For daily use, smooth calf leather or vulcanised rubber offer practicality without compromising the aesthetics of the stainless steel satin-finished case.

Use a dedicated strap removal tool or a small screwdriver to remove the pins securing the strap to the case lugs. Gently push the pin from one side to the other, keeping the watch stabilised on a soft surface (such as microfibre cloth). During extraction, protect the case with watchmaker's tape (painter's tape) to prevent scratches on the outer edge of the bezel. Insert the new strap by aligning the holes with the lugs and reintroduce the pins from the opposite side.

Yes, provided the strap is specifically dimensioned for 18 mm lug width. Before purchase, verify the manufacturer's specifications and compare images of the strap with your personal photographs of the case. Optimal performance is achieved with straps manufactured by specialist makers using quality materials (alligator with vegetable tanning, shell cordovan, vegetable-tanned calf). Avoid generic straps from online platforms that do not certify compatibility with luxury watch models.

The lifespan of a natural leather strap depends on the tanning process, usage, and maintenance. Premium vegetable-tanned leather (alligator, shell cordovan, calf) can last 3 to 7 years if worn daily; the patina developed over time further increases the aesthetic value of the accessory. To prolong strap life, alternate it regularly with other models, avoid prolonged exposure to direct heat sources, and apply a specific leather conditioner every 12 months. Vulcanised rubber, as an alternative, offers superior durability (5–10 years) due to its inherent wear resistance.
