Strap for Senator Excellence Panorama Date Moonphase Stainless Steel / Silver / Synthetic

The lug width of the Glashütte Original Senator reference 1-36-04-01-02-34 is 21mm. This is a non-standard dimension in the watch industry, requiring specifically calibrated spring bars to ensure proper fit without lateral play. Correct measurement is performed by positioning a digital calliper perpendicularly between the two lugs, touching the inner shoulders of the case lugs.

There is no universally superior choice, but rather selections coherent with intended use and desired aesthetics. For a formal and sartorial context, a strap in alligator leather with vegetable tanning or high-quality European calf represents the natural pairing. For versatile use and moisture resistance, NATO-style synthetic fibre straps or FKM rubber models offer practicality without compromising the proportions of the case.

Strap replacement is accomplished by removing the two lateral pins that secure the strap to the case lugs. Utilise a dedicated spring bar removal tool to depress the pin on one side, extracting it completely. Subsequently, position the new strap by inserting the pin into the lug seat, ensuring the internal spring of the pin is correctly seated. Repeat the procedure on the opposite side. This operation should be performed on a flat surface with adequate lighting.

Yes, aftermarket straps designed specifically for the 21mm lug width are available. At milanostraps.it, straps can be selected in leather (alligator, calf, shell cordovan with vegetable tanning), NATO-style straps in synthetic fibres, and FKM rubber straps. All straps are manufactured with spring bars calibrated specifically for 21mm lugs, ensuring both mechanical and aesthetic compatibility with the Senator.

The lifespan of a leather strap depends on material quality, frequency of use, and maintenance. A high-quality alligator or calf strap, used daily, has an estimated lifespan of 3 to 5 years before replacement is required. A shell cordovan strap, owing to its density and resistance, may last 7-10 years. The patina that develops over time is not a defect, but a desirable characteristic that testifies to the natural ageing of the leather.
