Strap for Conquest Quartz 25 Ceramic

The lug width of the Longines Conquest L3.157.4.87.6 is 12mm, a non-standard specification requiring dedicated straps. This compact dimension is determined by the 25mm case geometry. To verify compatibility, measure the distance between the inner shoulders of the lugs using callipers; it must be exactly 12mm.

For the Conquest L3.157.4.87.6, we recommend alligator straps in black or dark brown to emphasize the sporty aesthetic, or vegetable-tanned calf leather for progressive patina development. A grey-anthracite NATO or technical rubber strap are pragmatic choices for frequent strap rotation. The material must respect the 12mm lug width and proportion to the delicate 25mm diameter.

Position the watch with the lugs facing upward on a soft cloth. Use a spring bar removal tool to access the elastic pins anchoring the strap to the lugs. Gently press the pin towards the case centre, sliding the strap outward. When inserting the new strap, align the holes with the pins and push them into position until you hear a click. Verify that the strap is securely fastened before wearing the watch.

A quality leather strap worn daily lasts an average of 2–4 years, depending on the leather type, exposure to perspiration and humidity, and the care applied. Shell cordovan and vegetable-tanned alligator offer superior durability and develop a fascinating patina. Milano Straps straps benefit from an 18-month warranty. Regular maintenance with natural waxes significantly extends service life.
