Strap for Conquest Heritage Power Reserve 38 Pink Gold / Silver

The lug width (misura ansa) of the Longines Conquest Heritage L1.648.8.62.2 is 19mm. This measurement represents the distance between the holes of the front and rear spring bars. To measure correctly, use a digital calliper positioned perpendicular to the hour-minute axis. Verifying the lug width is essential before ordering a strap, as even half a millimetre difference will compromise the spring bar fit.

For a pink gold watch, alligator leather represents the ultimate luxury choice: its regular granular texture emphasizes the metal's brilliance without competing for attention. Alternatively, shell cordovan develops a deep patina over time that resonates with aged pink gold, creating a sense of temporal unity. Vegetable-tanned calf leather offers a more accessible yet equally elegant option, ideal if you desire a naturally visible and evolving patina.

To change the strap, you will need a spring bar tool. Position the watch with the front spring bar facing you, insert the tool's tip into the small lateral hole of the spring bar, press gently outward until the spring bar releases from the lugs, then remove the old strap. Repeat from the other side. To fit the new strap, align the lug holes with the rear spring bar holes, insert the spring bar into the hole, then press until it clicks. Do the same from the front, ensuring the spring bar is fully seated.

Yes, you can use any strap with a 19mm lug width, provided it has been constructed to quality standards. Aftermarket straps of quality have identical functional performance to original straps and often offer greater colour choice and artisanal materials. Verify that the strap width is proportionate to the 38mm case size and that the spring bar notch does not prevent a secure fit.

The durability of a leather strap depends on the quality of the leather and intensity of use. A premium alligator or shell cordovan strap can last 4–6 years with regular rotation and proper maintenance. A calf leather strap, being more delicate, typically lasts 2–4 years. Maintenance includes storage in a dry environment, avoiding prolonged direct sunlight exposure, and for shell cordovan, occasional cleaning with a soft brush. Some straps, particularly aged shell cordovan, can be restored or reconditioned by specialist artisans.
