Strap for Conquest Quartz 34 Stainless Steel / White

The lug width of the Longines Conquest L3.377.4.16.6 is 17 millimetres. This non-standard dimension must be measured perpendicularly on the case, from inner shoulder to inner shoulder of the two lugs. It is critical to verify this measurement before purchasing an aftermarket strap, as 17mm is a relatively uncommon width in the generic market.

The optimal strap depends on intended use and aesthetic preference. For a classical-formal approach, alligator in teak or walnut tones is ideal, ensuring harmonious proportions and a texture that does not compete with the case. Shell cordovan offers exceptional longevity and develops a natural patina over time. Calf leather with vegetable tanning is perfect for refined daily wear, developing authentically biological character. Rubber in black or navy blue is recommended for sporting situations or heavy usage.

The strap is changed by removing the spring bars that connect the strap to the case lugs. Using a dedicated spring bar tool, perpendicular pressure is applied to compress the internal spring mechanism, creating the necessary space to extract the strap. After removing the previous strap, the new one is inserted by aligning the holes with the spring bars, applying pressure until the closure click is heard. This operation requires delicacy to avoid scratching the case.

Yes, aftermarket straps specifically designed for 17mm lug width are available. Milano Straps offers a dedicated collection of 17mm straps in various leathers and finishes, customisable in length, initials, and stitching type. It is essential to purchase from specialised suppliers who understand this non-standard dimension to ensure compatibility without measurement errors.

The lifespan of a leather strap depends on the material, frequency of use, and maintenance. Artisanal-quality alligator typically lasts 5-8 years with regular use. Shell cordovan can exceed 10 years due to its natural density. Vegetable-tanned calf leather, being more absorbent, typically lasts 3-5 years with daily use, though it develops a compelling patina. Milano Straps provides periodic replacement and 18-month warranty on straps created by the Casati Milano atelier.
