This model continues the Conquest lineage established in 1954 as an official timing instrument for world competitions.

Frequently asked questions

What is the lug width of the Longines Conquest L3.836.4.52.9?

The lug width is 22mm. This specification refers to the internal distance between the spring bars that connect the bracelet to the case lugs. To verify compatibility with your watch, remove the current strap and measure the transverse space between the bars: 22mm is the standard for this model and ensures geometrically perfect seating of any compatible bracelet.

Which strap is best for the Longines Conquest L3.836.4.52.9?

The Conquest L3.836.4.52.9 with stainless steel and ceramic case pairs excellently with Tuscan leather in vegetable tanning, available in Honey or Dark Brown tones. For those seeking luxury refinement, Nile alligator in dark shades dialogues silently with the case materials. Those requiring sporting versatility can opt for a NATO in Cordura with stainless steel keepers, ideal in high-humidity environments or during outdoor activities. Your choice depends on the desired balance between formal aesthetics and environmental functionality.

How do you change the strap on the Longines Conquest L3.836.4.52.9?

To change the strap, obtain a spring bar removal tool. Insert the flat tip of the remover into the small lateral groove of the pin, gently push inward to compress the spring, then extract the pin. Repeat on both sides of the case. Once the pins are removed from the old strap, insert them into the lugs of the new 22mm strap and secure them in the case lugs with uniform pressure until you hear the locking click. Avoid sudden movements to prevent pin damage.

Can I use an aftermarket strap on my Longines Conquest L3.836.4.52.9?

Yes, any strap with a 22mm lug width is compatible. Ensure that the strap has been dimensioned specifically for this measurement and that the spring bars are compatible with the case lugs. Custom-made leather straps available online allow variations in thickness, tip shape, and thread colour to precisely match your style. For personalised consultation and bespoke construction, the Casati Milano atelier operates by appointment, offering direct material selection with an 18-month warranty.

How long does a leather strap last on the Longines Conquest L3.836.4.52.9?

Leather strap durability depends on usage, material quality, and maintenance. A quality Tuscan leather in vegetable tanning, worn daily, maintains structural functionality between 3 and 5 years. Prolonged exposure to humidity, perspiration, and direct sunlight accelerates ageing. Nile alligator or shell cordovan, owing to natural fibre density, can endure 6 to 8 years with proper care. The natural patina developing over time is a desirable characteristic and part of the material's aesthetic evolution, not a flaw. Store your strap away from extreme humidity and occasionally apply conditioner specifically formulated for vegetable-tanned leather.
