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

The lug width is 21mm, measured between the inner edges of the two attachment holes on the case. This measurement must be verified using a digital calliper before ordering a strap, as manufacturing tolerances may vary slightly on vintage examples.

For the Senator 1-36-02-02-05-30 in red gold, we recommend alligator in vegetable tanning with a dark brown or hazel tone, which reinforces the Saxon aesthetic and allows natural patina development. Alternatively, shell cordovan in vegetable tanning develops deep patina and offers superior durability. Full-grain calf remains the versatile option for those seeking understated modernity.

Remove the deployant clasp from the case using a dedicated spring bar tool. Place the watch on a soft cloth to prevent scratching. Carefully extract the old strap by pressing the lateral springs of the lugs. Insert the new 21mm strap while maintaining balanced tension on both sides, ensuring the springs click correctly into the holes. We recommend this procedure be performed by specialist ateliers.

Yes, the Senator accepts all straps with a 21mm lug width that meet European manufacturing standards. We recommend artisanal brands that respect rigorous construction protocols: thickness 3.5-4.5mm to maintain case proportions. Always verify that the original or compatible deployant is in rose gold for aesthetic coherence.

An alligator or calf strap of quality with vegetable tanning lasts 4-6 years with moderate daily wear, 6-8 years with occasional use. Shell cordovan reaches 8-10 years. Durability depends on sun exposure, ambient humidity, and conditioning frequency. We recommend seasonal rotation with NATO straps to extend leather strap lifespan.
