Strap for 1815 Moonphase Emil Lange Pink Gold

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> is 19 millimetres. This measurement is standard across all case material variants of the 231.031 (rose gold, white gold, platinum). Always verify lug width before ordering a strap, as an 18mm or 20mm strap will not be compatible with the Lange lugs.

Given the classical refinement of the 1815, noble materials are ideal: <a href="/pages/termine-glossario/alligatore">alligator</a> leather in cognac or chocolate tones to complement the pink gold, or vegetable-tanned calf with subtle grain in neutral shades (brown, black, burgundy). For a sportier aesthetic, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> in burgundy offers unparalleled patina development. Avoid overly rigid or rubber straps, which would contrast the understated elegance of the transparent caseback.

The 1815 employs straight lugs (not curved). Strap changes involve inserting a straight spring bar through the lug holes and securing the new strap on both sides. A dedicated lug removal tool is recommended to prevent damage to the rose gold case. Those inexperienced with this procedure may visit Casati Milano atelier, where the operation is performed by appointment with precision.

Yes, provided the <a href="/pages/termine-glossario/misura-ansa">lug width</a> is precisely 19mm. Compatible artisanal straps are available in our online catalogue, or bespoke through Casati Milano with direct leather selection and colour customisation. A high-quality aftermarket strap does not diminish the watch's value and instead allows personal expression whilst respecting Saxon craftsmanship.

Longevity depends on frequency of wear and material type. Alligator or shell cordovan with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> typically lasts 5–8 years with 4–5 days weekly wear. Vegetable-tanned calf resists for 3–5 years under identical conditions. All Casati Milano straps carry an 18-month warranty against manufacturing defects. Minimal maintenance—annual leather conditioning and moderate humidity exposure—significantly extends lifespan.
