Frequently asked questions
What is the lug width of the Longines Conquest L3.661.4.56.2?
The lug width is 21 millimetres. This measurement is the gap between the spring bars and the strap itself: any aftermarket strap must be cut to exactly 21mm in width to ensure precise fit and mechanical safety. There are no construction tolerances: even one millimetre of error compromises both aesthetics and security.
Which strap do you recommend for the Conquest L3.661.4.56.2?
For this reference, we recommend genuine alligator in black or dark brown, which amplifies the technical character of the ceramic black bezel. If you prefer tactile softness, Italian vegetable-tanned calf in burgundy or dark brown creates sophisticated chromatic harmony. For sport-chic use, a vulcanised rubber deployante of Racing type maintains practicality and readability without requiring custom perforation.
How do I change the strap on a Longines Conquest?
The strap is fixed to the case via two spring bars inserted into the lugs. Using a spring bar tool or small flathead screwdriver, apply pressure to the bars to extract them from the slots, then remove the strap. To install the new one, insert the bars into the case lugs until they lock into original position. Verify that the strap is centred and the bars are fully seated.
Is an aftermarket strap compatible with the Conquest L3.661.4.56.2?
Yes, any artisanal strap cut to exactly 21mm in width is compatible, regardless of brand. The important factor is that the lug width is precise and the spring bars are standard type (1.8mm diameter). Always consult the seller to confirm compatibility before purchasing.
How long does a leather strap last on the Longines Conquest?
Durability depends on daily wear, care, and material chosen. Genuine alligator with vegetable tanning typically lasts 3–5 years in intensive daily use with regular maintenance (cleaning and wax treatment). Standard calf lasts 2–3 years. Vulcanised rubber resists 4–6 years if protected from prolonged direct sunlight exposure. Every quality artisanal strap can be refurbished by a specialist craftsman, extending its service life.
