Strap for Senator Excellence Panorama Date Moonphase Stainless Steel / Silver / Alligator / Folding

The lug width of the Senator 1-36-04-01-02-61 is 20 millimetres. This measurement is obtained by inserting a rigid calliper between the two case lugs, from inner edge to inner edge. It is essential to respect this dimension when selecting an aftermarket strap to ensure correct fit without play or excessive tension.

For the Senator 40mm in stainless steel, alligator remains the choice most aligned with the watch's Saxonian dignity. However, vegetable-tanned calf leather develops a rich patina over time, NATO fabric allows informal versatility, and FKM rubber guarantees performance in active environments. The choice depends on intended use and the desired dialogue between case and strap.

Strap replacement requires a dedicated tool: a variable-thickness spring bar removal tool. Position the watch with the lug suspended, locate the spring bars connecting the strap to the lugs, and gently push from the opposite side using the tool. Never force: the case steel is delicate. If inexperienced, consult a specialised watchmaker.

Aftermarket straps compatible with the Senator must respect the 20mm lug width specification. Milano Straps offers a dedicated collection of 20mm straps in alligator, calf, NATO, and rubber, selected for construction quality and longevity. Every strap is tested prior to dispatch to ensure compatibility and safety.

The lifespan of a leather strap depends on intensity of use and environmental conditions. With moderate daily use, a high-quality alligator or calf strap offers 3-5 years before replacement becomes necessary. Vegetable tanning develops a patina that characterises the strap over time, whilst excessive humidity may accelerate ageing. Periodic maintenance (gentle cleaning, air drying) significantly extends strap life.
