Strap for Senator Excellence Stainless Steel / Silver / Alligator - Folding

The lug width of the Glashütte Original Senator 1-36-01-01-02-61 is 20mm. This construction specification, determined by the proportion between the case diameter (40mm) and the lug geometry, represents the internal distance between the contact points where the strap anchors to the case. To verify compatibility of an aftermarket strap, measure with a digital calliper the internal space between the lugs: it must be exactly 20mm.

For the Senator 1-36-01-01-02-61, we recommend three options based on usage: (1) alligator with vegetable tanning for formality and progressive aesthetic patina; (2) Japanese shell cordovan for robustness and character development over time; (3) FKM rubber for daily use in humid climates or demanding environments. NATO in cotton is recommended for those desiring rapid-change versatility. Avoid undersized straps (18mm) which cause lateral movement, and oversized straps (22mm) that compromise case aesthetics.

The Senator uses fixed lugs (spring bars are not removable without disassembly). To change the strap, insert a dedicated tool (spring bar remover) or a small flathead screwdriver into the lower slot of the lug, apply upward pressure to disengage the internal spring, then extract the lug from the new strap. Reverse operation for installation. If inexperienced, consult a qualified watchmaker to avoid case scratches. Milano Straps offers support for correct installation.

Yes, provided the strap is dimensioned precisely at 20mm lug width. Aftermarket straps of quality (alligator, shell cordovan, vegetable tanned leather, rubber) are fully compatible with the Senator, provided they are manufactured by reputable makers who respect construction tolerances. Avoid economically manufactured straps, which often present tolerance variability and may cause excessive play. Milano Straps certifies every 20mm strap for compatibility with this model.

Leather strap durability depends on tanning method and intensity of use. Vegetable-tanned alligator, worn daily, resists 3-5 years before structural failure at the buckle area. Shell cordovan, owing to dense fibre structure, extends this duration to 6-7 years. Cotton NATO resists up to 8-10 years if submitted to periodic washing. FKM rubber remains functional beyond 10 years without aesthetic deterioration. Wear is not a defect but patina: a consciously aged strap maintains aesthetic value and can be regenerated by a specialised craftsperson.
