Strap for Senator Perpetual Calendar Red Gold / Black / Rubber / Pin

The lug width of the Glashütte Original Senator 100-02-25-05-06 is precisely 20mm. This measurement represents the internal space between the pins that secure the strap to the case. It is essential not to confuse lug width with strap thickness: the strap must have a total width of 20mm at the case attachment to ensure proper fit on the rose gold case.

The ideal strap for the Senator 100-02-25-05-06 in rose gold depends on intended use. For formal and dress wear, we recommend alligator or vegetable-tanned calf leather in dark brown, burgundy, or black. For more versatile and contemporary contexts, natural calf with vegetable patina offers elegance without rigidity. An FKM rubber strap represents a practical choice without sacrificing aesthetic authority. The deployante, if present, must match the rose gold case colour.

Strap replacement requires attention to two critical details: first, use a dedicated spring bar tool to extract the connecting pins from the case. Never force with improvised tools. Position the watch on a soft surface to avoid scratching the rose gold. Gently extract the pin, allow the straps to separate, and insert the new strap ensuring the pin is completely seated. For a rose gold case, we recommend performing this operation wearing cotton gloves to avoid fingerprints on the surface.

Yes, the Senator 100-02-25-05-06 accepts any well-crafted 20mm artisanal strap with solid construction and finishing consistent with the rose gold case. Milano Straps offers a specialised collection of compatible 20mm straps, crafted from premium leather with vegetable tanning, technical rubber, and NATO options. The important thing is to verify that the strap is correctly dimensioned and that the deployante, if present, has no sharp edges that could scratch the rose gold during wear.

Leather strap durability depends on usage and maintenance. A quality vegetable-tanned calf or alligator, with moderate wear and proper care, lasts approximately 3-5 years. If you wear the Senator daily in formal contexts, the strap may require replacement within 2-3 years. Premium leather develops a natural patina that increases aesthetic value over time. We recommend alternating the strap with other models to extend its life and applying a natural protectant every 6 months to preserve suppleness.
