Strap for Admiral GMT Grey Bracelet

The lug width of the Longines Admiral L3.668.4.79.6 is 20 millimetres. This measurement is determined by the distance between the case lugs and is critical for selecting the correct strap. Any strap with a 20mm lug width is fully compatible with this model.

Selection depends on intended usage. For formal occasions, we recommend alligator in dark shades or cognac shell cordovan. For daily wear, vegetable-tanned leather offers durability and authentic patina development. For sports activities, a NATO in cordura or a rubber strap provides practicality and reliability without compromise.

Strap replacement involves removing the spring bars connecting the strap to the lugs. Using a dedicated tool, gently push the spring bar to one side to free the lug, then extract the old strap. The new strap is inserted by aligning the holes with the lugs and snapping the spring bars into position. This operation requires care to avoid case damage.

Yes, any artisanal or commercial strap with a 20mm lug width is completely compatible with the Longines Admiral L3.668.4.79.6. No case modifications are required. Aftermarket straps often offer superior construction quality and carefully selected materials compared to standard offerings.

Durability depends on leather quality and usage conditions. An artisanal alligator or shell cordovan strap typically lasts 3-5 years of regular wear. Vegetable-tanned leather tends to age faster visually but retains structural integrity. Exposure to moisture, perspiration and UV rays accelerates wear. Proper maintenance and periodic drying significantly extend useful life.
