Strap for BelleArti 19 Quartz Stainless Steel

The lug width of the Longines Heritage L2.194.4.73.3 is 12mm. This is a non-standard measurement, narrower than most wristwatch cases, resulting from the compact 19mm case diameter. Correct measurement should be taken using a digital calliper, measuring the distance between the inner walls of the lugs, which should be between 11.8mm and 12.2mm for precise fitment.

For the Longines L2.194.4.73.3, we recommend straps in Mississippi alligator with natural quadricellular grain, or smooth calf in vegetable tanning for a more restrained aesthetic. Shell cordovan is ideal if you desire a structured leather with superior constructive density. NATO textile straps remain a lightweight and versatile choice for warmer seasons. Avoid modern glossy silicones, which do not respect the vintage character of the case.

Remove the strap using a spring bar tool. Extract the pin from the right lug by pulling the small hook downwards, thereby removing the pin from its seat. Repeat the operation on the left side. Insert the new strap by threading the pin through the lateral openings and pressing until it clicks into place. We recommend proceeding with caution on such a compact case to avoid scratches to the brushed steel finish.

Yes, any aftermarket strap with a 12mm lug width is compatible with the Longines L2.194.4.73.3. Milano Straps offers a complete collection of 12mm straps customisable in leather, sizing and stitching. It is essential to verify that the lug width is exactly 12mm to avoid excessive play or friction in the lugs. Casati Milano atelier also creates bespoke straps made to measure with direct leather selection.

The lifespan of a leather strap depends on the material, daily usage and maintenance. A quality vegetable-tanned or alligator strap has a useful life of 3-5 years of regular wear. Shell cordovan, thanks to its superior density, can last 5-7 years. Longevity increases significantly if the strap is not constantly exposed to moisture, chlorine or chemical agents. Milano Straps guarantees 18 months on all bespoke straps, but long-term durability is enhanced by the quality of vegetable tanning and correct periodic maintenance.
