Strap for Conquest Chronograph Quartz 41 Stainless Steel / Blue / Bracelet

The lug width of the Longines Conquest L3.702.4.96.6 is 21mm. This measurement is specific to this model and tolerates no variance: an undersized strap (20mm) will sit loose, whilst an oversized one (22mm) will create abnormal pressure on the case shoulders. The measurement must be verified using a calliper inserted perpendicularly between the lug pins, midway between the case shoulder and the inner edge of the lug seat.

Nile crocodile alligator is the most versatile choice for this chronograph, with its asymmetrical scale pattern permitting both sporty and formal styling. For those who appreciate visible ageing, European calf leather with vegetable tanning develops characteristic patina over time. Japanese shell cordovan offers exceptional initial rigidity and surface finish, whilst FKM rubber is ideal for tactical functionality and humid-environment wear.

Strap change requires extraction of the spring bar using a specialised bifurcated tool (bayonet-style). Insert the forked ends of the spring bar into the lateral holes on the lugs, depress gently toward the case centre, and withdraw the spring bar with the strap. The operation demands care to avoid scratching the case. For repeated changes, consultation with a specialist watchmaker is advisable.

Yes, any aftermarket strap with verified 21mm lug width is compatible with the Longines Conquest L3.702.4.96.6, provided the measurement is confirmed with millimetre precision. Bespoke artisanal straps from Milano Straps and Casati Milano guarantee zero tolerance on lug width. Avoid suppliers who do not certify lug measurement, as even minor variations cause instability or accelerated shoulder wear.

A bespoke artisanal leather strap (alligator, calf, shell cordovan) maintains structural integrity and functionality between 3 and 7 years, depending on daily wear, UV exposure, ambient humidity, and tanning method. Vegetable-tanned leather tends to age more rapidly but develops compelling patina. An FKM rubber strap typically lasts 5–10 years before losing elasticity. Casati Milano provides an 18-month warranty on all custom straps, regardless of material.
