Strap for Senator Perpetual Calendar Stainless Steel / Silver / Synthetic

The lug width of the Glashütte Original Senator 1-36-02-01-02-36 is 18mm. This measurement is taken from the internal face of the lug, measuring the distance between the two symmetrical holes designed to house the strap's spring bars. It is essential to verify this specification before purchasing an aftermarket strap to ensure compatibility and proper fit without undesired play or tension.

For the Senator 1-36-02-01-02-36, three primary options are recommended: niloticus alligator for formal occasions, thanks to its regular scale pattern and natural patina development; European calf with vegetable tanning for those seeking an evolved and personalised patina; hydrophobic rubber for sports contexts whilst maintaining visual elegance. The choice depends on intended usage and colour preferences: the 42mm stainless steel case accommodates both neutral and striking combinations.

Strap removal is performed by extracting the two lateral spring bars using a dedicated removal tool called a spring bar extractor. Position the watch on a soft surface, gently compress the inner spring bar using the tool, extract the bar, and release the old strap. Repeat the operation on the opposite side. For installing the new 18mm strap, insert the spring bars already housed in the new strap into the two lugs, ensuring the bar is fully seated in its housing and does not protrude. A properly positioned strap should not move laterally on the case.

Any strap with an 18mm lug width is compatible with the Senator 1-36-02-01-02-36, regardless of material (leather, rubber, NATO, canvas). MilanoStraps offers several certified artisanal options ranging from fine leathers such as alligator and shell cordovan to cotton and silk straps. It is important to verify that strap thickness aligns with the case lug thickness (approximately 2.5–3.5mm) to ensure harmonious transitions and absence of misalignment.

A quality natural leather strap, worn daily, maintains full functionality for 3–5 years depending on usage frequency and climatic conditions. Premium materials such as niloticus alligator and shell cordovan with vegetable tanning tend to age more elegantly, developing a patina that increases aesthetic value over time. Leather fears direct moisture and chlorine; it is advised to dry the watch after accidental contact with fresh water and to avoid complete submersion. A strap in good condition may be rejuvenated through professional reconditioning or replacement of the rubber backing.
