The Conquest Heritage L1.649.4.02.2, seen from the bench

The Longines Conquest Heritage L1.649.4.02.2 reinterprets the classic 1950s Conquest sports watch with modern refinement. This 38mm stainless steel model features a clean dial, rotating bezel, and the Longines L888.5 ND chronograph movement—an ETA-derived certified chronometer mechanism. Water-resistant to 300 meters with scratch-resistant sapphire crystal, it combines functional elegance with reliable Swiss craftsmanship. Lug width: 19 mm.

Frequently asked questions

What is the lug width of the Longines Conquest Heritage L1.649.4.02.2?

The lug width is 19 millimetres. This measurement represents the distance between the two suspension pins on the case. It is essential to verify this measurement precisely before purchasing a replacement strap, as it is not compatible with standard 18mm or 20mm solutions.

What is the best strap for the Longines Conquest Heritage L1.649.4.02.2?

The choice depends on your intended use. For formal elegance, we recommend cognac brown or black alligator. For a sporty-elegant profile, vegetable-tanned calf leather in natural tones is ideal. For everyday wear and absolute water resistance, dark grey FKM rubber offers practicality and visual restraint.

How do you change the strap on the Longines Conquest Heritage L1.649.4.02.2?

Use a spring bar tool to gently lift the suspension pins. The first pin is extracted by rotating the tool towards the case; the second is removed by pulling the old strap and inserting the new one. The operation requires no technical expertise, or you may entrust it to a specialist atelier such as Casati Milano.

Are there compatible aftermarket straps available for this lug width?

Yes. Milanostraps offers a dedicated collection of 19mm straps, crafted with premium materials (alligator, calf, rubber, shell cordovan). All straps are customisable in length, stitch colour and initials, with rapid delivery and quality guarantee.

How long does a leather strap last on a sports watch like the Conquest Heritage?

A quality alligator or calf leather strap, used regularly, lasts 24–36 months. Durability depends on water exposure, perspiration, frequency of use and maintenance level (periodic cleaning, conditioning with natural creams). Casati Milano atelier provides an 18-month guarantee on all bespoke straps.
