Strap for Senator Automatic Red Gold / Silver / Alligator / Pin

The lug width of the Glashütte Original Senator 1-39-59-01-05-04 is exactly 20 mm (centre-to-centre distance between lugs). This specification is model-specific and should be verified using a digital calliper, measuring the distance precisely between the attachment pins on the red gold case.

For a dress watch of the Senator's calibre, recommended straps include: alligator with vegetable tanning for formal elegance, vegetable-tanned calf in brown or black for daily versatility, and woven NATO for sport-casual wear. Alligator is preferable owing to its fine, natural grain texture, which complements the dress character of the red gold case.

Strap replacement involves removing the pins or spring bars securing the strap to the case lugs. Use a dedicated pin remover tool to gently push the pins downward and withdraw them. Align the new strap's lugs with the case lugs and reinsert the pins until they click securely into place. This operation is best performed by an experienced watchmaker to prevent damage to the red gold case.

Yes, the 20 mm lug width is a standard specification, permitting the use of quality aftermarket straps: leather (alligator, calf, cordovan), NATO in Cordura or woven cotton, and FKM rubber for sports use. Always verify lug width compatibility and ensure the strap edges are smooth to prevent marking the case lugs.

Strap longevity depends on tanning method, frequency of use, and maintenance practices. A vegetable-tanned calf strap typically lasts 3–5 years with daily wear; alligator or shell cordovan straps, thanks to denser natural structure, may exceed 7–10 years. Exposure to moisture, perspiration, and direct sunlight accelerates degradation. Regular maintenance—dry cloth cleaning, occasional gentle washing with neutral soap—significantly extends lifespan.
