Strap for BelleArti 16 Stainless Steel Diamond

The lug width of the Longines Heritage L2.195.0.83.6 is 10 millimetres. This measurement is determined by the distance between the spring bars protruding from the lateral lugs of the case. It is essential to respect this exact width to ensure that the strap is compatible and properly mounted without excess material or excessive tension.

For the L2.195.0.83.6, we recommend straps in fine-grained alligator, vegetable-tanned calf leather, or vegetable rubber. Alligator reflects the historical authenticity of the watch whilst maintaining a sober texture. Vegetable-tanned calf develops a natural patina over time. Rubber is ideal for those who prefer minimal maintenance. Avoid oversized straps or those with excessively pronounced texture, which would unbalance the proportions of the 15.9 mm case.

To change the strap, gently remove the old strap by pushing the spring bars inward from the lateral lugs, using a dedicated tool (spring bar tool) or a thin plastic or metal rod. Once the lugs are free, align the new 10 mm strap with the holes and reattach the spring bars by pushing firmly until they snap into place. Verify that the strap is equidistant on both sides of the case.

A strap is compatible with the L2.195.0.83.6 if it has a lug width of exactly 10 millimetres. Measuring from the centre of one spring bar to the centre of the other, you should obtain 10 mm. Note: some labels may indicate width approximately. Always verify the technical specifications provided by the seller or have the strap measured directly by an expert before purchase.

The lifespan of a leather strap depends on the quality of the material, intensity of use and maintenance. A high-quality alligator or vegetable-tanned calf strap typically lasts 4–8 years with daily wear and regular maintenance (brushing, drying after moisture exposure, occasional application of appropriate creams). Leather fears prolonged sweat and moisture. Rotating multiple straps extends the lifespan of each. Vegetable rubber straps have similar longevity but require less maintenance.
