Strap for BelleArti 27.3 Pink Gold Diamond

The lug width (lug to lug distance) of the Longines Heritage L2.694.9.83.6 is 20mm. This is the internal distance between the two straight pins protruding from the case where the strap is inserted. The 20mm represents the optimal proportion for the 27.30mm case diameter, guaranteeing aesthetic balance without appearing either tight or disproportionate.

For the Longines Heritage L2.694.9.83.6 in rose gold, we recommend three primary options: alligator in vegetable tanning for sartorial tradition and patina development over time; smooth calf leather for aesthetic minimalism and uniform reflectivity; shell cordovan for rich patina and warm tones akin to rose gold. For humid environments, vulcanised rubber offers waterproofing without formal compromise.

Changing the strap on the L2.694.9.83.6 involves removing the two straight pins (spring bars) that connect the strap to the case lugs. Using a dedicated tool (spring bar tool), you compress the internal spring of the pin, extracting the old strap. The operation takes a few minutes and requires no technical expertise. Casati Milano offers personalised strap-change service by appointment.

A quality leather strap (alligator, calf, shell cordovan) lasts an average of 4–7 years with daily wear, varying with frequency of use and tanning type. Vegetable-tanned leather develops a protective patina over time, extending durability. Vulcanised rubber resists 5–10 years without significant aesthetic degradation. Casati Milano guarantees 18 months on internally manufactured straps, providing guidance on maintenance and preventive pin replacement.
