The Heritage

The Longines Conquest Classic L2.387.0.87.6 is a 36mm stainless steel timepiece featuring a mother-of-pearl dial with ceramic inserts and a black ceramic bezel. It is powered by the Longines caliber L156 movement, beating at 28,800 vibrations per hour and displaying hours, minutes, seconds, and date. The 18mm lug width requires a specific strap size to ensure proper visual proportion and wrist comfort.

FAQ

What is the lug width of the Longines Conquest Classic L2.387.0.87.6?

The lug width of the Longines Conquest Classic L2.387.0.87.6 is precisely 18 millimetres. This width is specific to the 36-millimetre case model and ensures correct proportions between the case and strap. To verify compatibility, measure with a digital calliper from inside to inside of the lug holes, or check the keeper loop on the original strap.

What is the best strap for the Conquest Classic L2.387.0.87.6?

The choice depends on usage and personal preference. For a classical approach, we recommend dark brown alligator or cognac calf leather, which enhance the instrument-like austerity and dialogue perfectly with the mother-of-pearl dial. For sports contexts or high-humidity environments, a fine-grained rubber offers practicality whilst maintaining elegance. Patinated shell cordovan represents a middle ground, with a natural patina that evolves over time.

How do I change the strap on my Longines Conquest Classic L2.387.0.87.6?

Strap replacement is a straightforward operation. Use a dedicated tool to remove the spring bars (or consult a professional watchmaker). Insert the new spring bars into the new strap, align the axes with the case holes and push gently until they lock. Always ensure the spring bars are fully seated and the strap is perfectly aligned before wearing the watch.

Can I use an aftermarket compatible strap with my Conquest Classic L2.387.0.87.6?

Absolutely. Aftermarket 18-millimetre straps are fully compatible with the Conquest Classic L2.387.0.87.6, provided they respect the exact lug width. Straps in alligator, calf, shell cordovan, NATO canvas and rubber of artisanal quality guarantee comfort and durability equivalent to or superior to original straps, with greater aesthetic versatility.

How long does a leather strap last on the Longines Conquest Classic L2.387.0.87.6?

The lifespan of a leather strap varies depending on material, usage and maintenance. A quality artisanal alligator strap typically lasts 3–5 years with daily wear, whilst shell cordovan can last 5–7 years thanks to its natural density. Rubber offers greater resistance in humid environments. With proper care – regular cleaning and drying after exposure to moisture – longevity extends significantly.
