Strap for Senator Excellence Perpetual Calendar Red Gold / Silver / Alligator - Folding

The lug width of the 42mm Senator in rose gold is 21 millimetres. This measurement represents the distance between the two lateral lugs of the case where the strap inserts. It is essential to verify this dimension with a digital calliper before ordering an aftermarket strap, measuring between the inner edges of the lugs.

For the Senator 1-36-02-02-05-61 in rose gold, we recommend a vegetable-tanned alligator strap in dark brown or cognac tones, or premium continental calf. Both materials create aesthetic continuity with the rose gold without competing visually. For daily use, a black or brown FKM rubber strap is practical and versatile.

Changing the strap requires minimal tools: a spring bar tool (lug lever) and a small file. Insert the lever into the lateral lug slot, gently lift the internal spring, extract the old strap. Align the new strap to the lugs and press the spring until it clicks shut. Verify the strap slides uniformly without play. Proceed with care to avoid scratching the rose gold case.

Yes, any quality strap with a 21mm lug width is perfectly compatible. It is essential to verify the strap dimensions; incorrect straps (20mm or 22mm) will not insert correctly. MilanoStraps offers artisanal 21mm straps in various materials, all tested for compatibility with the Senator.

A premium alligator or calf strap with vegetable tanning has an average lifespan of 4-6 years with daily use. Longevity depends on humidity, sun exposure and cleaning frequency. FKM rubber straps last 5-8 years. To extend strap life, rotate between multiple straps (every 2-3 weeks) and clean periodically with a damp cloth.
