Strap for Senator Moon Phase White Gold / Skeleton / Alligator / Pin

The Glashütte Original Senator 1-49-13-15-04-01 features a 21mm lug width. This measurement represents the distance between the two internal lugs of the case and must be respected rigorously to ensure proper strap accommodation. An incorrect width would result in accelerated mechanical wear and strap instability.

For the Senator 1-49-13-15-04-01 in white gold, alligator leather remains the primary formal choice: the natural grain texture does not compete with the case's lustre, creating visual balance. Alternatively, vegetable-tanned calf develops a patina over time that synchronises ageing with the white gold. For daily wear, technical NATO fabric maintains elegance without functional compromise.

Strap replacement requires specialised tools: a spring bar tool to compress the springs that fix the strap to the case lugs. Position the tool in the small hole at the base of the lug, gently compress the internal spring, and the strap will slide out. The reverse process secures the new strap. For high-value watches such as the Senator, we recommend having the operation performed by a specialised service.

Yes, provided the aftermarket strap is specifically shaped for a 21mm lug width. Milanostraps.it offers artisanal leather straps of excellence, alligator, shell cordovan and structured rubber, all certified 21mm. A high-quality aftermarket strap enhances versatility of use whilst maintaining aesthetic coherence with the case.

The lifespan of a leather strap varies according to material, UV exposure and frequency of wear. An alligator or vegetable-tanned calf, worn daily, visibly develops a patina after 12–18 months of daily wear, reaching optimal aesthetics after 24–36 months. Occasional wear (3–4 times per week) extends this window to 4–5 years. Vulcanised rubber maintains structural properties for 2–3 years, with gradual degradation thereafter.
