The Conquest L3.835.4.72.6, seen from the bench

The Longines Conquest L3.835.4.72.6 is the contemporary evolution of a legacy begun in 1954 when the Swiss manufacture introduced the first Conquest chronograph for sailors and mountaineers. This 42mm model houses the automatic Longines L898.5 calibre, visible through the sapphire caseback, offering hours, minutes, small seconds counter and separate chronograph function with ±4-6 seconds per day precision. The stainless steel case features high-tech ceramic inserts on the bezel for scratch resistance and durability. The 22mm lug width is proportioned to the 42mm diameter and 14.6mm thickness for comfortable wrist wear and stable strap mounting.

Frequently asked questions

What is the lug width of the Longines Conquest L3.835.4.72.6?

The lug width of the Longines Conquest L3.835.4.72.6 is 22mm. This measurement corresponds to the distance between the two strap attachment pins on the original strap and is compatible with all 22mm artisanal straps in our collection.

Which strap pairs best with the Longines Conquest L3.835.4.72.6?

We recommend alligator in tobacco brown or Italian vegetable-tanned calf leather for the Conquest L3.835.4.72.6. Both create sophisticated contrast with the stainless steel and ceramic case whilst maintaining the model's sporting character. Choice depends on use: alligator for everyday elegance, calf for natural patina development over time.

How do I change the strap on a Longines Conquest L3.835.4.72.6?

Use a spring bar removal tool. Position the watch with the lug side facing upward, insert the tool's tip into the small hole at the base of the spring bar, press gently inward and slide the pin out of the lug. Repeat for the opposite lug and secure the new strap by reversing the procedure.

Can I use an aftermarket strap on a Longines Conquest L3.835.4.72.6?

Yes, provided it is certified for 22mm lug width. Milano Straps' artisanal straps are engineered to ensure complete compatibility with your watch. Verify that the strap lugs leave minimal clearance on the pins and do not rest directly on the case.

How long does a leather strap last on a Longines Conquest L3.835.4.72.6?

A quality vegetable-tanned leather strap lasts approximately 4–6 years in daily wear, depending on sun exposure and humidity. Alligator tends to age more elegantly, developing a sought-after patina. Milano Straps offers an 18-month warranty on all artisanal straps and free maintenance assistance.
