Strap for Legend Diver 36 Stainless Steel / Burgundy / Strap

The lug width of the Longines Legend Diver L3.374.4.40.2 is 19mm. This measurement indicates the distance between the inner edges of the two case lugs and determines strap compatibility. Always verify with a digital calliper, measuring perpendicular to the lug surface, to avoid reading errors due to inclination.

For the Legend Diver, straps in dark alligator, shell cordovan, vegetable-tanned calf leather or vulcanised rubber are recommended. Choice depends on usage: fine leathers for formal and elegant sport contexts, rubber for genuine diving environments. Alligator and shell cordovan emphasise sophistication whilst maintaining the watch's military heritage.

To change the strap, use a spring bar tool or sterile needle. Position yourself before a light source, locate the spring bar pin inside each lug, compress it slightly towards the case centre, and slide the strap outward. Repeat for the opposite end. Installation of the new strap follows the reverse procedure, verifying that the spring bar is securely anchored.

Yes, any 19mm strap is compatible, as the case lugs follow the universal lug width standard. Ensure the strap features spring bar pins or is designed for your attachment system (standard spring bars or quick-release). Artisanal straps from Milano Straps are specifically crafted for this size and guarantee complete compatibility.

A quality leather strap, correctly maintained, typically lasts 3–5 years of daily wear. Longevity depends on frequency of use, thermal and humidity fluctuations, and tanning method. Vegetable-tanned or shell cordovan leathers age better, developing patina, though they require periodic cleaning with dry cloths. Milano Straps offers 18-month warranty on personalised straps created at Casati Milano atelier.
