Strap for Senator Observer Stainless Steel / Black / Calf - pin

The lug width is 21 millimetres. This dimension is specific to the Senator case and determines compatibility with aftermarket straps. Correct measurement should be taken from the inner edge of the right lug to the inner edge of the left lug, perpendicular to the case body.

Alligator leather in vegetable tanning represents the most coherent solution with the Senator's identity: the fine grain harmonises with the case's elegant proportions, whilst the patina evolves with time. Structured calf leather maintains elegance without formal rigidity. Technical rubber is recommended for sports use, maintaining proportions respectful of the case.

Changing the strap on this case requires removal of the spring bars. Position the watch on a stable surface, use a dedicated tool (spring bar remover) to depress the internal spring mechanism and extract gently. Insert the new strap ensuring correct alignment and verify that the spring bar is fully seated on both sides.

Yes, provided it is constructed with the correct lug width (21 mm) and thickness coherent with the case. Quality artisanal aftermarket straps ensure precise fit and longevity. We recommend selecting materials that respect the Senator's identity: alligator, structured calf, appropriately weighted technical rubber.

Longevity depends on material and usage. Vegetable-tanned alligator typically lasts 3-5 years with average daily use, developing progressive patina. Structured calf has similar durability. FKM rubber resists for 2-4 years before showing initial ageing. Proper maintenance (drying after moisture exposure, avoiding excessive heat) significantly extends strap life.
