Strap for BelleArti 25 Quartz Stainless Steel

The lug width of the Longines Heritage L2.501.4.73.2 is 15mm. This is an uncommon measurement in the market, reflecting the feminine proportions of the 24.60mm case diameter. To verify, insert a calliper or ruler into the space between the two lugs (case horns) and measure from the centre of one to the other.

For the Longines Heritage L2.501.4.73.2, we recommend an alligator with vegetable tanning in cognac or dark brown: the regular texture of the reptile pairs perfectly with the intimate proportions of the 24.60mm case, and the natural patina of vegetable tanning evolves over time. Alternatively, fine-grain calf or suede offer lightness and discreet elegance.

Changing the strap on the Longines Heritage L2.501.4.73.2 is done via the lateral spring bars. Gently push the spring bar towards the centre of the case with a thin tool (strap removal tool or knife point); the bar will retract and the strap will detach. Align the new strap with the lugs, insert the spring bar through the passant, and allow it to expand naturally into position.

Yes, the Longines Heritage L2.501.4.73.2 is fully compatible with quality 15mm aftermarket straps. It is essential to verify that the strap has spring bars or passants adapted to this specific measurement, as 15mm is not a universal standard. At milanostraps.it you will find a selection of 15mm straps in various materials, sizes and finishes.

A quality alligator or calf strap, subject to normal daily wear, lasts on average 3-5 years before replacement is needed. Lifespan depends on the type of tanning (vegetable tanning is more resistant to light but more fragile to moisture than chrome tanning), frequency of use and care. Protecting the strap from prolonged sun exposure and moisture significantly extends its life.
