Strap for Hydroconquest Automatic 41 Silver

The lug width of the Longines HydroConquest L3.671.4.76.6 is 20 millimetres. This measurement is specific to this model and should be measured between the spring bar attachment terminals. A strap with a different width will not fit correctly into the case lugs.

Selection depends on intended use: for elegant daily wear, vegetable-tanned calf leather in cognac or hazelnut tones; for maritime character, satinous brown alligator; for saltwater and moisture resistance, black FKM rubber; for discreet luxury, burgundy shell cordovan. The 20mm lug width must always be respected.

The Longines HydroConquest L3.671.4.76.6 features standard 20mm spring bar lugs. To change the strap, use a spring bar tool: insert it into the lug opening, lift the internal spring, remove the old strap, and insert the new one. Perform this operation with care to avoid scratching the case.

Yes, any strap with standard 20mm attachments is compatible. We recommend bespoke artisanal straps: they allow you to select leather type, colour, stitching, and patina development, ensuring superior customisation and quality compared to generic industrial products.

Durability depends on tanning quality and usage: vegetable-tanned calf lasts 3–5 years with daily wear; alligator 5–7 years; shell cordovan 10+ years with proper care. Exposure to sunlight, saltwater, and perspiration accelerates ageing. An 18-month warranty is standard for quality artisanal straps.
