Strap for Conquest Automatic 39 Ceramic

The lug width of the Longines Conquest L3.655.4.86.6 is 19 mm. This measurement represents the distance between the two lugs of the case and is essential for selecting a compatible strap. You can verify it using a digital calliper, measuring directly between the lugs without touching the bezel of the case.

The best strap depends on primary usage. For formal contexts, alligator or calf leather in dark brown enhance the mother-of-pearl dial, creating aesthetic harmony. For casual-elegant wear, taupe grey, navy blue or burgundy offer versatility. NATO fabric straps are ideal for daily practicality and moisture resistance, whilst FKM rubber guarantees water resistance and thermal flexibility.

Changing the strap on the Longines Conquest L3.655.4.86.6 is performed using a spring bar remover tool. Position the remover in the small slot on the side of the lug, gently press inward to release the spring bar, then extract the old strap. Insert the new strap into the spring bar (ensuring it is properly positioned) and press until you hear a click. For the first time, it is advisable to consult a professional watchmaker.

The lifespan of a leather strap depends on the quality of tanning and intensity of use. An alligator strap with vegetable tanning typically lasts 5-8 years with daily wear, gradually developing darker patinas. Calf leather offers similar longevity (4-7 years), whilst NATO fabric exceeds 10 years due to the absence of organic material subject to degradation. MilanoStraps guarantees 18 months on custom straps crafted at the Casati Milano atelier.
