Strap for Senator Perpetual Calendar Red Gold / Silver / Rubber / Folding

The lug width of the Glashütte Original Senator 100-02-22-05-53 is precisely 20mm. This measurement refers to the internal distance between the two spring bar pins that connect the strap to the case. It is essential to measure from the inside of one pin to the inside of the other to ensure correct compatibility with any aftermarket strap.

For a timepiece of this aesthetic and technical calibre, straps in natural alligator or vegetable-tanned calf represent the most coherent choices. Alligator imparts discrete luxury through its recognisable box pattern, whilst calf leather ages magnificently, developing character over time. Both materials dialogue elegantly with red gold without visual competition. A quality silk or cotton NATO strap also provides tactical versatility whilst maintaining constructive dignity.

Strap change is executed via spring bars: position the watch with the lug facing upward, use a spring bar tool (small extractor with forked end) to release the pin from the case, extracting the current strap. Insert the new strap by aligning its internal hole with the pin, then reinsert the pin into the case. Verify it is firmly secured on both sides. This operation should be performed on a soft surface to avoid scratches on the red gold case.

Yes, absolutely. Any strap with a 20mm lug width is compatible with the Glashütte Original Senator 100-02-22-05-53. Compatibility is guaranteed by the standardised lug width. We recommend selecting straps of elevated constructive quality, crafted from natural leather with artisanal finishing, so that the final aesthetic coheres with the technical value of the Glashütte movement.

A natural leather strap of artisanal quality (alligator, calf, shell cordovan) has an average lifespan of 3–5 years of daily wear, dependent upon climate, personal perspiration, and frequency of use. Vegetable-tanned leather straps age and develop patina rather than degrade: character increases over time. FKM rubber exhibits superior longevity (5–7 years), particularly useful in warm climates. A quality strap may be restored or regenerated by a specialised artisan.
