Strap for Conquest 39 Automatic White

The lug width of the Longines Conquest L3.676.4.16.6 is 19mm. This dimension is measured between the two lugs (vertical attachments) of the case and represents the usable space where the strap is inserted. A 19mm strap fits this model perfectly without lateral play.

The Conquest L3.676.4.16.6 pairs beautifully with various materials: alligator ensures elegance with restrained sportiness; calf leather withstands daily wear; crocodile is recommended for evening versions; NATO fabric in textile offers casual-sporty versatility. The choice depends on primary usage: outdoor sport, business context, or frequent alternation.

The Conquest L3.676.4.16.6 utilises a straight lug system. To remove the strap, minimal tools are required: a spring bar tool or a small flathead screwdriver. Light pressure is applied to one of the two lateral lugs, the entire bar is extracted, then the new strap is inserted by levering until it clicks into place. A delicate operation but executable autonomously with patience.
