Strap for Conquest V.H.P. 43 Stainless Steel / Carbon / Rubber

The lug width of the Longines Conquest V.H.P. L3.726.4.66.9 is 22 millimetres. This technical specification is measured as the distance between the lugs of the case. A compatible strap must have lugs dimensioned precisely at 22mm to ensure accurate fitting without looseness or tearing. This is the fundamental measurement to verify before purchasing any aftermarket strap.

The ideal strap depends on intended use: for formal contexts, alligator in vegetable tanning with a cognac or dark brown finish imparts elegance without excess; for daily and sports wear, thick calf leather in cognac or black offers durability and noble ageing; for aquatic environments, technical rubber maintains elasticity and grip. Your choice should harmonize with the grey or black dial of the Conquest, avoiding pastels that would diminish legibility.

Changing the strap requires a specialist tool (a spring bar tool). Place the watch on a soft surface, insert the tool into the tiny hole on the lug shoulder near the pin, and gently push the pin outward to extract it from the case. Repeat on the opposite side. Insert the new strap by threading the pins through the lug slots of the case. To avoid scratching, consider consulting a professional watchmaker.

Yes, all 22mm straps are compatible with the Conquest V.H.P. L3.726.4.66.9 owing to standardised lug width. Milano Straps offers a curated selection of straps in calf, alligator, shell cordovan, and rubber, customisable in length, initials, and stitching colour. Compatibility is guaranteed by the 22mm lug width, which is the international standard for this specification.

A high-quality leather strap, crafted with vegetable tanning and proper thickness (1.4–1.6mm), lasts 4–8 years with daily use, depending on climate and maintenance. Leather fears constant moisture and excessive heat: protect it from seawater, dry it promptly if wet, and store it in well-ventilated spaces. The ageing of leather is a feature, not a flaw: the patina that develops is evidence of artisanal quality.
