Strap for Conquest Chronograph Automatic 41mm Ceramic Grey

The Longines Conquest L2.744.4.06.7 features a lug width of 21mm. This measurement, whilst not a universal standard (which typically fall to 20mm or 22mm), is precise for this particular model and requires straps specifically dimensioned to avoid lateral play or unwanted pressure on the case.

For this stainless steel sports model, we recommend textured leathers with medium grain (Hermès calf, Nile alligator) or robust alternatives such as NATO military-grade fabrics or rubber. Your choice depends on intended use: aged leather for daily elegance, rubber or NATO for outdoor activity. Milano Straps provides 21mm straps customisable in colour, stitching thread and initials.

The strap attaches via two lateral lugs that pass through the case lugs. Using a spring bar tool, you remove the elastic pins from both sides, thereby releasing the old strap. The operation requires delicacy to avoid scratching the case; many prefer to entrust this task to a professional. Atelier Casati Milano performs strap changes at the studio by appointment.

Yes, provided the strap is specifically manufactured for 21mm lug width. The watch's lugs are calibrated to this exact measurement; a strap with 20mm or 22mm lug width will not attach correctly, creating harmful play. Always verify that your supplier certifies the precise lug width of your chosen strap.

A quality leather strap, worn with rotation (at least two straps for the same watch), maintains elasticity and durability for 3–5 years. Longevity varies with climate, frequency of wear and tanning method. Vegetable-tanned or Hermès leathers require periodic maintenance (balm, air-drying after rain). Rubber and NATO straps offer greater longevity, lasting 7–10 years.
