Frequently asked questions

What is the lug width of the Longines Legend Diver L3.774.4.60.2?

The Longines Legend Diver L3.774.4.60.2 features a lug width of 22mm. This dimension is determined by the geometry of the 42mm case and the lateral lugs, and represents the point of contact between the strap and the watch. To verify precisely, measure the internal distance between the lug walls using a digital calliper positioned perpendicularly.

What is the best strap for the Longines Legend Diver?

The Longines Legend Diver L3.774.4.60.2 pairs exceptionally well with straps in alligator with a coarse grain, Italian vegetable-tanned calf leather, or robust materials such as shell cordovan. For historically coherent choices, tobacco brown or dark brown tones dialogue naturally with the brushed steel case. For reliable daily wear, vegetable-tanned calf develops a natural patina that ages in harmony with the timepiece.

How do I change the strap on my Longines Legend Diver?

Changing the strap on the Legend Diver L3.774.4.60.2 is performed using standard tools: a spring bar tool to remove the elastic pins from the lateral lugs. Position the watch on a soft surface, insert the lever into the middle of the lug, gently lift to release the spring, and repeat on the opposite side. The new 22mm strap will fit easily into the vacant lugs. If uncertain, entrust the task to a specialist service centre.

Can I use an aftermarket compatible strap with the Legend Diver L3.774.4.60.2?

Yes, any strap with a 22mm lug width is compatible with the Longines Legend Diver L3.774.4.60.2. Artisanal leather straps in Tuscan leather, alligator, or vegetable-tanned calf fit into the lugs without issue. Always verify that the strap is cut for a 42mm case diameter and that the lug slots correspond to 22mm width.

How long does a leather strap last on a watch like the Legend Diver?

The longevity of a leather strap on the Legend Diver L3.774.4.60.2 depends on the tannage and use. Tuscan leather with vegetable tanning, worn daily under normal conditions, typically lasts 3–5 years before requiring maintenance or replacement. If frequently exposed to moisture, direct sunlight, or impacts, durability diminishes. Shell cordovan resists moisture longer; vegetable-tanned calf develops a protective patina over time. With proper care—regular cleaning and dry storage—the strap maintains structural integrity well beyond five years.
