Strap for Conquest Chronograph Quartz

The lug width of the Longines Conquest L3.660.4.76.6 is 21mm. This dimension is specific to the case geometry and requires precision when replacing the strap. An incorrect measurement would result in visual and functional misalignment.

For the Conquest L3.660.4.76.6, alligator straps with vegetable tanning are recommended for formal elegance, satin calf for constructive sobriety, or NATO straps for sporting versatility. The choice depends on primary use and desired personal aesthetic.

To change the strap, use a spring bar removal tool. Gently insert the blade under the pin, apply light pressure to release the internal spring, extract the pin and repeat on the other side. Proceed carefully to avoid scratching the satin stainless steel case.

Yes, you can use aftermarket straps provided they respect the 21mm lug width. Ensure the strap is constructed to adequate quality standards and that the side guides fit perfectly on the case lugs. Low-quality straps could compromise the overall fit and finish.

A quality leather strap (alligator or calf with vegetable tanning) typically lasts 3-5 years with daily wear. Lifespan depends on sun exposure, humidity and frequency of use. Vegetable-tanned leathers naturally patina, improving aesthetic appearance over time.
