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

The lug width of the Glashütte Original Senator 1-36-01-02-05-30 is precisely 20mm. This measurement is calculated as the distance between the inner shoulders of the lugs, not the overall case diameter. Accurate measurement is essential to ensure compatibility with aftermarket straps and to avoid visible gaps between the strap and case.

For the Senator in red gold, a dark brown or cognac alligator strap is the aesthetic reference choice. Alligator does not compete with the warm red gold tone; instead, it accentuates it through measured contrast. Alternatively, vegetable-tanned calf leather offers versatility and permits natural patina development over time. For more formal contexts, black provides neutral discretion.

Strap replacement requires a dedicated tool: the spring bar tool. Position the watch on a protected surface, insert the tool tip beneath the metal bar located under the lug, apply gentle pressure to destress the internal spring, and extract the bar carefully. Once removed, slide the old strap off and introduce the new one. For watches of significant value such as the Senator, consult Casati Milano, a bespoke atelier by appointment, where you can benefit from professional expertise and instrumentation.

Yes, provided the strap is dimensioned for 20mm lugs. High-quality aftermarket straps do not compromise the watch's integrity and offer greater aesthetic versatility than the original strap. Milano Straps supplies a curated selection of straps in alligator, calf, NATO, and rubber, specifically verified for compatibility with this lug width. Precise measurement verification prior to purchase is essential.

Leather strap longevity varies according to material type, intensity of use, and environmental conditions. An alligator or shell cordovan strap, vegetable-tanned and properly maintained, typically guarantees 4–6 years of daily wear before requiring replacement. Natural leather ages and develops patina—a process that is aesthetically desirable. To extend longevity, rotate multiple straps and protect leather from prolonged moisture exposure and direct intense sunlight.
