Strap for Conquest 34 Stainless Steel / Brown / Bracelet

The lug width (also called anse width) of the Longines Conquest L3.430.4.62.6 is 17mm. This precise measurement represents the space available between the case lugs where the strap is fitted. It is essential to use straps specifically dimensioned at 17mm to ensure correct fitting and harmonious aesthetics. Undersized straps (16mm) would be loose and unsightly, whilst oversized straps (18mm) would not fit the case guides.

The best strap choice depends on intended use and aesthetic preferences. Alligator represents the most formal and refined option, enhancing the case's elegant character and the blue sunray dial. Vegetable-tanned calfskin offers a balance between formality and comfort, developing a natural patina that improves over years. For casual use, rubber ensures resistance and practicality. Shell cordovan, finally, represents the most prestigious choice for superior longevity and organoleptic properties.

To change the strap, specific tools are required: a spring bar tool or a small flat screwdriver. Position the watch face-up, locate the small metal pins (spring bars) inside the lugs. Using the tool, gently push the pin downward to release the internal spring tension, then extract the pin from the old strap. Insert the pin into the new strap, position the pin in the case guides and release the tool to secure it. Repeat the procedure on the other lug. If you prefer to avoid the risk of damage, the Casati Milano atelier offers professional strap-change service.

Yes, the Longines Conquest L3.430.4.62.6 accepts high-quality aftermarket straps provided they are dimensioned exactly at 17mm lug width. Milano Straps offers a specialised collection of compatible straps in various materials (alligator, calfskin, rubber, cordovan) with customisation options. Technical compatibility is guaranteed; construction quality and longevity depend on material choice and manufacturing. Artisanal straps from certified ateliers offer aesthetic and functional advantages over industrial alternatives.

The lifespan of a leather strap depends on use, maintenance, and tannage quality. An alligator or vegetable-tanned calfskin strap, if properly maintained (avoiding excessive moisture and direct heat sources), can last 5-10 years or longer, developing character and patina over time. Rubber, more resistant to moisture, offers comparable lifespan but without the aesthetic ageing. The standard warranty for Casati Milano artisanal straps is 18 months, covering manufacturing defects. Leather wear is a natural process that increases its aesthetic value and vintage appeal.
