FAQ

What is the lug width of the Longines Legend Diver L3.374.4.90.2?

The Longines Legend Diver L3.374.4.90.2 features a lug width of 19 millimetres. This dimension represents the space between the two lugs of the case where the strap is secured via spring bars. It is an intermediate width, characteristic of versatile wristwatches, neither too narrow nor excessively wide.

What is the best strap for the Longines Legend Diver 36mm?

The best strap depends on the intended use. To preserve the formal elegance of the vintage model, we recommend alligator with vegetable tanning in brown or cognac tones, which highlights classical proportions. For evening contexts, black anilinated calf. For authentic marine functionality, high-modulus rubber or NATO textile. Shell cordovan represents the choice for exceptional craftsmanship, guaranteeing longevity beyond 10 years.

How do I change the strap on the Longines Legend Diver L3.374.4.90.2?

Obtain a spring bar removal tool (pen removal tool) designed for watches. Position the case on a soft surface (felt or mat), insert the remover into the groove of the spring bar, pushing gently until the bar is extracted. Repeat on both lugs. Align the new strap with the holes, reinsert the spring bars using the same tool, verifying the strap is perfectly centred. Seek assistance from a watchmaker if uncertain about the procedure.

Can I use an aftermarket strap on the Longines Legend Diver L3.374.4.90.2?

Yes, provided the strap is designed for a 19-millimetre lug width. Quality aftermarket straps (alligator, calf, shell cordovan with vegetable tanning) offer aesthetic personalisation whilst maintaining perfect compatibility. Verify the strap thickness suits the case (overly thick straps may create tension on spring bars). Opt for specialised brands that certify compatibility with luxury watches.

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

Durability depends on material and usage. An alligator strap with vegetable tanning typically resists 5-7 years with moderate daily wear, developing patina appreciated over time. Shell cordovan easily reaches 10-15 years due to superior structural density. Anilinated calf sits around 4-6 years. Continuous exposure to water or humidity reduces lifespan. Proper maintenance (regular drying, treatment with specific balms) significantly extends strap life.
