Strap for Conquest V.H.P. Chronograph 44 PVD / Black / Rubber

The lug width of the Longines Conquest V.H.P. L3.727.2.56.9 is 22 millimetres. This dimension was specifically designed to maintain correct visual proportions between the substantial 44mm case and the wrist. To verify compatibility, position a digital calliper between the inner faces of the case lugs, near the suspension pins: the value obtained must correspond to 22mm. This width is standard across all specimens of this reference.

For the Conquest V.H.P. L3.727.2.56.9, we recommend an alligator leather in vegetable tanning with fine grain, ideally in havana brown or cognac tones. This material enhances the technical nature of the watch by creating an aesthetic contrast with the brushed stainless steel case. If you plan frequent aquatic use, a black satin-finished FKM rubber strap ensures hydrophobicity and stability under stress. For daily versatility, naturally dyed calf leather with developing patina represents the ideal compromise between elegance and sport functionality.

The Conquest V.H.P. L3.727.2.56.9 strap is suspended via two straight-pin bars. Proceed as follows: 1) Position the watch on a soft support, dial facing up; 2) Identify the lateral pins that pass through the case lugs; 3) Use a spring bar tool to compress the small metal arch underneath the pin; 4) Gently pull the pin towards you until it comes out completely; 5) Repeat for the second pin; 6) Remove the old strap and insert the new one by reversing the procedure. Ensure both pins are fully secured before wearing the watch.

Any strap with a 22mm lug width is compatible with the Conquest V.H.P. L3.727.2.56.9, provided the lugs are straight (not curved) and the shoulders fit the case geometry. The most suitable straps are those in alligator, calf leather, FKM rubber and NATO-style nylon cordura, available from specialist suppliers. Ensure that the attachment thickness is between 4.5mm and 5.0mm for smooth passage between the lug and case. Avoid straps with lug width greater than 22mm, as they will not fit into the case eyelet holes.

A quality leather strap (alligator in vegetable tanning or fully tanned calf) on a Conquest V.H.P. L3.727.2.56.9 has an average lifespan of 2–4 years with moderate daily use. Factors affecting longevity include: frequency of use, water exposure, ambient humidity, type of tanning and quality of the starting leather. A vegetable-tanned leather subjected to constant moisture tends to rot if not properly maintained. FKM rubber straps, being hydrophobic, last 4–6 years even with frequent aquatic conditions. Regular maintenance (cleaning with damp cloth, air drying) significantly extends the useful life of any leather strap.
