Strap for Senator Excellence Perpetual Calendar Stainless Steel / Silver / Bracelet

The Glashütte Original Senator 1-36-02-01-02-71 is equipped with a lug width of 21 millimetres. This measurement is taken from the centre of one spring bar to the centre of the other on the same lug. The 21mm dimension is the construction standard for the Senator in its modern variants and ensures a broad selection of quality aftermarket straps.

For the Senator 42 in stainless steel, we recommend a vegetable-tanned alligator strap (in cognac, havana, or black tones) that emphasises the sober Germanic character of the case. Alternatively, thin vegetable-tanned calf leather maintains aesthetic dignity with greater practicality. For a more informal approach, a cotton or linen NATO strap represents a legitimate choice that does not compromise the elegance of the internal movement.

The strap is replaced by removing the two horizontal spring bars that connect the lugs to the case. Use a dedicated watchmaking tool (spring bar tool) to compress the internal spring of the bar and slide it outward. Insert the new strap by aligning the holes to the lugs, then reposition the bars carefully. This operation requires no specialist skills and is completely reversible.

Yes. All artisanal straps with 21mm lug width are compatible with the Senator 1-36-02-01-02-71. MilanoStraps manufactures straps in vegetable-tanned leather, alligator, and certified synthetic materials in this size. The quality of an aftermarket strap depends on the selection of leather, the tanning process, and the stitching: we recommend choosing specialised suppliers who document the origin of their materials.

A quality vegetable-tanned leather strap, worn daily, has an average lifespan of 3 to 5 years before requiring replacement. Durability depends on usage frequency, environment (humidity, extreme temperatures), and maintenance (avoid prolonged contact with water, apply conditioners periodically). Alligator tends to age better than calf leather, developing a patina that increases its aesthetic appeal over time.
