Strap for BelleArti 19 Quartz Stainless Steel Black

The lug width of the Longines Heritage L2.194.4.53.6 is precisely 12 millimetres. This measurement represents the internal clearance space between the two case lugs where the strap is inserted. It should be measured with a digital calliper perpendicular to the case axis, between the internal base of the two metal spring bar holes. It is important not to confuse this dimension with the total case width, which is 19 millimetres.

For this heritage timepiece, alligator leather in vegetable tanning is the most coherent choice with the collection's formal identity. The natural texture of the leather harmonises perfectly with the case's satin-finished surfaces and develops an evolving patina over time. Alternatively, embossed calf leather or crocodile alligator offer excellent wear resistance, whilst for sporting use rubber or charcoal silicone straps are suitable alternatives.

Durability depends on leather quality and frequency of use. A premium quality alligator or calf leather strap with vegetable tanning maintains structural and aesthetic integrity between 3 and 5 years with daily wear. The natural patina that develops enhances aesthetic value. Factors such as humidity, perspiration and extreme temperatures can reduce this lifespan. We recommend seasonal rotation with alternative straps to extend each strap's life and protect the case lugs from repeated stress.
