Strap for BelleArti 27.3 Stainless Steel Diamond

The lug width of the Longines Heritage L2.694.0.83.4 is 20mm. This dimension is determined by the distance between the two spring bars that hold the strap to the case. It is essential to verify this measurement before purchasing an aftermarket strap to ensure perfect mechanical compatibility.

For the Longines Heritage L2.694.0.83.4, we recommend alligator straps in cognac or tobacco tones, or vegetable-tanned calf leather that develops patina over time. Classic striped NATO fabric straps also pair perfectly with the vintage aesthetic of this model, maintaining the dimension of practical elegance that characterises the watch.

To change the strap, use a removable spring bar tool to gently push the small metal pins inward that support the strap. Once released, the strap slides away from the case. Insert the pins of the new strap into the same holes and release gradually: the pin will reposition itself automatically. If you are not comfortable doing this, a professional watchmaker will complete the operation in a few minutes.

Yes, the Longines Heritage L2.694.0.83.4 accepts any aftermarket strap with a 20mm lug width. Straps in leather, fabric, rubber and metal are compatible. We recommend choosing high-quality materials and reliable brands to preserve the vintage aesthetic of the watch and guarantee comfort and durability over time.

A quality leather strap on a Longines Heritage L2.694.0.83.4, with moderate daily use, lasts an average of 2-4 years before requiring replacement. Durability depends on leather quality, tanning method used and maintenance level. Vegetable-tanned calf tends to last longer than chrome-tanned leather, developing a desirable patina. The Casati Milano atelier guarantees 18 months on bespoke straps and uses selected tanneries to maximise longevity.
