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

The lug width of the Glashütte Original Senator 1-36-04-03-02-51 is precisely 21mm. This dimension is specific to this model and derives from the proportional relationship Glashütte Original applies between the case diameter (42mm) and the lug attachment points. A 20mm strap would appear undersized, while a 22mm strap would create excessive play. Respecting this exact measurement is fundamental to preserve the aesthetic harmony of the composition and ensure proper fit within the lug seats.

For the Senator 1-36-04-03-02-51, alligator represents the supreme choice from both aesthetic and formal perspectives. The grain texture is naturally symmetrical, the deep colour evolves over time, and the patina that develops creates a sober, authoritative effect. Alternatively, vegetable-tanned calf leather offers robust character and visible ageing that documents the wearer's relationship with the watch. Shell cordovan is an option for those who accept initial aesthetic sacrifice in favour of extraordinary longevity: the moisture resistance and brown patina that develops after 3-4 years is exceptional.

Strap replacement requires precision and the correct tools. The procedure: (1) position the watch on a soft surface with the case facing downward; (2) use a spring bar tool to remove the elastic pins that secure the strap; (3) slide the used strap out of the lugs; (4) align the new strap and reintroduce the elastic pins, ensuring they are completely seated in their positions. If you lack technical expertise, strap replacement at a specialised watchmaker is recommended to avoid damage to the case.

Yes, it is entirely possible and recommended. Using quality aftermarket straps does not compromise the movement warranty, provided that installation is executed with care. The essential condition is that the strap is compatible with the 21mm lug width. An artisanal strap in alligator, calf, shell cordovan or NATO textile represents both an aesthetic and functional choice: it allows you to adapt the watch to different contexts (formal, sporty, casual) without altering the case. Quality aftermarket straps often exceed the durability of original straps.

Durability depends on material, frequency of use and maintenance practices. An alligator or vegetable-tanned calf strap typically lasts 4-6 years with daily wear and regular maintenance (cleaning and annual conditioning with specialist products). Shell cordovan, thanks to its natural density and moisture resistance, can last 8-10 years or longer. Deterioration begins with small cracks forming at the fold; at this stage the strap remains functional for another 6-12 months. Avoiding prolonged exposure to chlorine, salt water and direct heat sources significantly extends strap lifespan.
