Strap for Langematik Perpetual Pink Gold / Bracelet

The Saxonia 310.232 features a lug width of 20 mm. This is a specific measurement that is not standard for many watchmakers, so it is essential to verify this exact dimension before purchasing a replacement strap. Using a digital caliper to measure the distance between the case lugs ensures complete compatibility.

Alligator leather in dark brown tones is the most natural choice: its uniform grain pattern dialogues perfectly with the rigorous geometry of the pink gold case. Alternatively, napped calf leather with vegetable tanning offers greater versatility and a patina that improves with time. For a more formal look, burgundy shell cordovan creates a sophisticated pairing with the warmth of rose gold.

The 310.232 uses standard springbar attachments. To change the strap: 1) Remove the springbar from one side using a dedicated tool (springbar remover); 2) Slide off the old strap; 3) Insert the new strap, verifying that the 20 mm width is correct; 4) Reinsert the springbar until it clicks into place. We recommend entrusting the operation to a professional to avoid damage to the case.

Yes, any artisanal strap with a 20 mm lug width is compatible with the 310.232. Compatibility depends solely on the lug width (20 mm) and the strap thickness, which must not exceed the case parameters. Straps made to measure by ateliers such as Casati Milano guarantee construction quality and finishing that honours the prestige of the watch.

The lifespan of a leather strap depends on frequency of wear, leather quality and environmental conditions. A high-quality alligator or shell cordovan strap with vegetable tanning typically lasts between 3 and 5 years if worn daily. A napped calf leather tends to last between 2 and 4 years. Exposure to humidity, perspiration and sunlight accelerates ageing. Casati Milano offers an 18-month guarantee on manufacturing defects for all artisanal straps.
