Strap for Conquest 34 Quartz Moonphase Stainless Steel / Black / Bracelet

The lug width of the Longines Conquest L3.381.4.58.6 is 17mm. This dimension is specific to this model and is essential for ordering compatible straps. You can verify it by measuring the distance between the two external lug pins of the case using a digital calliper.

For the Conquest 34mm, we recommend a brown or burgundy alligator for elegance, or vegetable-tanned calf for those who appreciate natural leather ageing. If you prefer sportive versatility, a nylon resin-coated NATO or a sports rubber are excellent choices. Selection depends on the watch's primary use.

The change requires a specific tool called a spring bar removal tool (or lug pin extractor). Insert the tip into the lateral groove of the case lug and gently push to extract the pin. Repeat on the other side. Position the new strap and reinsert the pins, verifying they are fully seated. If unfamiliar, contact a professional watchmaker.

Yes, provided it is a 17mm strap. Quality aftermarket straps, such as those from milanostraps.it, are fully compatible with this case and often offer greater aesthetic choice than official replacements. Always verify the lug width before ordering.

A quality artisanal leather strap lasts an average of 3–5 years with daily use, depending on exposure to moisture, climate, and maintenance. Vegetable-tanned straps age elegantly, developing a natural patina. With regular care (drying after water contact, periodic conditioning), longevity extends. Artisans at Casati Milano offer an 18-month warranty on their straps.
