Longines
Conquest Classic L2.386.4.72.6— lug 17mm

The lug width of the Longines Conquest Classic L2.386.4.72.6 is 17.00mm. This measurement represents the internal distance between the two pins supporting the watch lugs. It is essential to verify this dimension when purchasing an aftermarket strap to ensure perfect compatibility and a secure fit without lateral play.

The optimal strap choice depends on context. For formal elegance, black dyed alligator is recommended; for daily versatility, fine-grained calf leather with vegetable tanning that develops patina naturally over time. Shell cordovan offers artisanal luxury with progressive colour evolution. Grey-dark NATO canvas ensures practicality without aesthetic compromise. The 17mm lug width allows seasonal experimentation across materials.

Strap replacement requires a dedicated tool (spring bar tool). Remove the two lateral pins securing the lugs by pressing the micro-lever of the tool, withdraw the old strap, insert the pins into the new strap aligning them with the two lateral lugs, then press until the locking click engages. Casati Milano atelier offers this service by appointment to guarantee impeccable assembly without case damage.

Lifespan varies based on leather type, usage intensity and climatic conditions. Shell cordovan tends to last longer due to superior fibre density.
