Strap for Conquest Chronograph Quartz 41 Stainless Steel / Silver / Strap

The lug width of the Longines Conquest L3.702.4.76.5 is 21mm. This specific configuration requires bespoke straps as it falls between military standard (18mm) and common civilian widths. You can verify it by measuring the distance between the inner shoulders of the lugs with a ruler: the value must be exactly 21mm. milanostraps.it offers a dedicated collection of compatible and customisable straps.

The ideal strap depends on your intended use. For elegance and sport: Nile or Mississippi alligator with vegetable tanning, which enhances the watch's technical solidity. For everyday versatility: Italian calf leather with fine grain that develops a personalised patina. For water sports or hiking: ballistic nylon NATO or reinforced FKM rubber with steel keeper. All materials are available in 21mm lug width at Atelier Casati Milano by appointment.

To change the strap, you need a dedicated spring bar removal tool or professional assistance from a watchmaker. Position the watch with lugs facing upward, locate the small hole or slot on the lug shoulder, insert the pin tool and push downward to release the spring. Repeat for the opposite lug. Install the new strap by reversing the procedure. If preferred, Atelier Casati Milano performs strap changes free of charge with quality assurance.

Yes, provided they meet the exact 21mm lug width specification. Lower quality straps with poor construction tolerances risk creating play or difficulty in positioning. All 21mm straps on milanostraps.it are tested for mechanical and aesthetic compatibility with the Conquest. Atelier Casati Milano also offers bespoke customisations with direct leather selection.

A quality leather strap (vegetable-tanned alligator or Italian calf) lasts 3 to 7 years with daily use, depending on maintenance and humidity exposure. Vegetable-tanned leather develops patina and hardens over time; calf is more prone to sweat absorption but offers superior comfort. Avoid prolonged rain, direct sun and excessive humidity. FKM rubber straps last longer (10+ years) but lose elasticity. Atelier Casati Milano offers 18-month warranty and regeneration services.
