Strap for BelleArti 16 Stainless Steel Black

The lug width of the Longines Heritage L2.195.4.53.4 is 10mm, a non-standard size that requires bespoke strap construction. This measurement is taken from the tip of one lug end to the other, excluding metal thickness. It is essential to respect this specification to ensure correct installation and balanced closure.

For the L2.195.4.53.4, alligator leather with vegetable tanning represents the premium solution, with natural grain that elegantly contrasts the case's compactness. Alternatively, French Taurillon calf offers chromatic versatility and smooth grain that emphasizes case details. The choice depends on occasion: alligator for formal wear, calf for versatility.

Changing the strap on the L2.195.4.53.4 requires specific tools: a spring bar remover to gently extract the spring pins that held the original strap, then insert the new pins into the custom strap and secure them to the case. We recommend having this operation performed by a specialized atelier to avoid case damage.

Yes, aftermarket straps can be used provided they are specifically constructed for 10mm lugs. Standard straps for different sizes (12mm, 14mm) will not fit correctly and may compromise case aesthetics. Milano Straps provides bespoke leather straps that respect the L2.195.4.53.4's construction specifications.

Leather strap durability depends on material and usage intensity. Vegetable-tanned alligator, if properly maintained, can last 5-8 years with daily wear, developing an aged patina that increases aesthetic value. Calf offers similar durability, around 4-7 years. Milano Straps straps include an 18-month warranty against manufacturing defects and hidden flaws.
