Strap for Conquest 34 Stainless Steel / Pink / Bracelet

The lug width of the Longines Conquest L3.430.4.99.6 is 17 millimetres. This non-standard dimension requires careful strap selection to ensure smooth insertion into the lug holes without play. Always verify the measurement using a digital calliper or millimetre ruler, measuring the distance between the inner edges of both lugs.

For your Conquest, we recommend alligator or shell cordovan straps: both materials emphasise classical elegance whilst maintaining the case's sporty character. Alligator offers natural grain and understated luxury; shell cordovan develops an unparalleled patina over time. Vegetable-tanned calf leather is perfect for those valuing ethical sourcing and breathability. Avoid overly thick straps: with a 34mm case, visual proportion is paramount.

You will need a spring bar tool to change your strap. Place the watch on a soft surface, locate the small metal pins protruding from the lugs, and insert the pointed end of the tool beneath the pin, applying gentle downward pressure. The pin will yield, allowing you to extract the strap. Repeat for the other lug. Reverse the procedure when installing the new strap, ensuring both pins are fully seated in their grooves.

Yes, any strap with a certified 17mm lug width is compatible with your Conquest. However, pay attention to lug depth (strap thickness): overly thick straps may create resistance during insertion. We recommend straps from specialised artisans who respect millimetre tolerances and use quality-certified materials to ensure longevity and comfort.

Lifespan depends on material, frequency of use, and environmental conditions. Quality alligator or shell cordovan resists 3–5 years with daily wear, developing patina and character. Vegetable-tanned calf maintains structure for 2–4 years, requiring occasional maintenance (gentle cleaning and conditioning). Natural ageing is not a defect but part of genuine leather's charm. Protect your strap from excessive moisture and dry it gently after water contact.
