Strap for Conquest Classic Quartz 34 Stainless Steel / MOP

The lug width of the Longines Conquest Classic L2.386.4.87.6 is 17 millimetres. This is a narrow lug width, not standard in the aftermarket strap market. To verify compatibility, measure the space between the two lugs with a digital calliper: the value must be between 16.8 and 17.2 millimetres.

For this model, we recommend natural alligator with vegetable tanning, which emphasises the dress aesthetic and develops patina over time. Alternatively, European calf treated with natural oils offers softness and versatility. Avoid NATO and rubber, which contrast with the delicate proportions of the 34 mm case.

Remove the watch from your wrist. Use a spring bar tool to gently push the retaining spring at the top of the lug, freeing the strap from the case. Insert the new strap by following the reverse path, ensuring the spring clicks into position. Proceed with both lugs before wearing the watch.

Yes, as long as the lug width is exactly 17 millimetres. Many standard straps have different sizes (16 mm or 18 mm). On milanostraps.it you will find a selection of compatible 17mm straps, personalizable and handcrafted. Casati Milano atelier also creates bespoke solutions with dedicated consultation.

Durability depends on the material and usage. An alligator strap with vegetable tanning typically lasts 4-6 years with moderate moisture and perspiration exposure. European calf has similar durability but requires more maintenance. All bespoke straps from Casati Milano come with an 18-month warranty and can be refurbished after initial wear.
