Frequently asked questions
What is the lug width of the Longines Conquest L3.659.4.76.6?
The lug width (ansa) of the Longines Conquest L3.659.4.76.6 is 21mm. This measurement corresponds to the distance between the internal steel pins that support the strap. A compatible strap must fit snugly without lateral gaps.
What is the best strap for the Longines Conquest L3.659.4.76.6?
For a 41mm stainless steel Conquest, alligator leather is the ideal choice: the structured grain enhances the tool watch sportiness, whilst the construction durability guarantees longevity. Shell cordovan is an excellent alternative for those seeking deep patina and visible ageing. Vegetable-tanned calfskin offers daily simplicity and restraint.
How do you change the strap on a Longines Conquest?
To change the strap, remove the watch from your wrist. Using a small screwdriver or spring bar tool, gently press the steel pin on one side of the strap towards the watch case: the pin will release. Repeat on the other side. Insert the new strap by aligning the pins into the lug slots and pressing until you feel a click.
Is an aftermarket 21mm strap compatible with the Longines Conquest L3.659.4.76.6?
Yes, any strap with a 21mm lug width is compatible with the Conquest L3.659.4.76.6, regardless of brand. Always verify the strap width is exactly 21mm (distance between internal pins): an oversized or undersized strap will not fit correctly.
How long does an artisanal leather strap last on a Longines Conquest?
A high-quality leather strap (alligator, cordovan, calfskin) typically lasts 3–5 years with daily wear, depending on storage and tanning method. Vegetable-tanned leather develops patina and colour over time, improving aesthetically. A replacement during the watch's lifespan (10+ years) is realistic and recommended to maintain wearing comfort.
