Strap for Conquest Chronograph Ceramic Leather

The lug width of the Longines Conquest L3.661.4.56.0 is 21 millimetres. This measurement represents the distance between the case lugs that connect the strap. It is essential to verify this specification before purchasing an aftermarket strap to ensure perfect compatibility.

For the Longines Conquest L3.661.4.56.0, we recommend alligator straps for formal elegance, vegetable-tanned leather for daily comfort, or NATO straps in dark tones for a sport-tactical character. Your choice depends on use case: formal, casual, or outdoor. 21mm straps guarantee full compatibility with this model.

To change the strap on the L3.661.4.56.0, use a spring bar tool. Position the watch on a soft surface, locate the pins on each lug, gently press with the tool to release them, remove the old strap and insert the new one by aligning the pins into the slots. If you lack experience, contact Casati Milano for professional strap replacement.

A quality leather strap, worn daily, maintains functionality and aesthetics for 3–5 years depending on tanning method, use and environmental exposure. Vegetable-tanned leather ages beautifully and develops a compelling patina over time. Casati Milano guarantees 18 months on its bespoke straps, covering manufacturing defects and hidden leather flaws.
