Strap for Senator Excellence Panorama Date Moonphase Stainless Steel / Grey / Bracelet

The lug width of the Glashütte Original Senator 1-36-04-03-02-70 is 21mm. This width is specifically calibrated for the 42mm case proportions and ensures correct visual balance. To verify it precisely, place a digital calliper perpendicular to the two attachment holes: the internal distance must correspond to exactly 21mm.

For the Senator 1-36-04-03-02-70, we recommend primarily alligator leather in vegetable tanning or shell cordovan, materials that naturally dialogue with the steel patina and the visible finishing of the Glashütte 36-04 calibre. Satin calf in neutral tones (cognac, black, anthracite) represents an elegant alternative for daily wear. For informal contexts, FKM rubber offers lightness and resistance. All straps must be in 21mm lug width.

Strap replacement requires a dedicated tool (spring bar tool). Insert the tool's tip into the small lateral hole of the lug to compress the internal spring, then extract the metal pin (spring bar) at both ends. Replace the strap by positioning the new spring bar in the housings and releasing the pressure. For valuable timepieces such as the Senator, we recommend entrusting the operation to a specialised service centre.

Yes, any aftermarket strap in 21mm lug width is compatible with the Senator 1-36-04-03-02-70, provided the end housings are correctly sized for the spring bar. We recommend choosing straps from specialised manufacturers that guarantee precise tolerances. A deployant clasp is highly recommended for this category of timepiece, as it ensures security and micro-adjustments.

A quality leather strap (alligator, shell cordovan, calf) typically lasts 2-5 years with constant daily use, depending on moisture exposure, perspiration and care. Vegetable-tanned alligator tends to last longer than calf, developing a desirable patina. To maximise longevity, we recommend rotating at least two straps, allowing natural drying between uses, and avoiding prolonged exposure to salt water.
