What I'm asked about the Longines Legend Diver L3.674.4.50.9
What strap size does the Longines Legend Diver L3.674.4.50.9 take?
The Longines Legend Diver L3.674.4.50.9 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Longines Legend Diver L3.674.4.50.9 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.
Can I put a leather strap on the Longines Legend Diver L3.674.4.50.9?
Yes, in 22 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 42 mm diver I go for a full-thickness strap, not a thin one.
Which strap do you recommend for the Longines Legend Diver L3.674.4.50.9?
Rubber if you wear it in the water; otherwise a 22 mm calf strap, full thickness. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
What is the best strap for the Longines Legend Diver L3.674.4.50.9?
The ideal strap depends on intended use. For heritage narrative and versatility, vegetable-tanned Tuscan leather in vintage brown or vegetable-tanned alligator are excellent choices: they develop elegant patina and resist moisture. For recreational diving, nylon NATO or FKM rubber ensure practicality and rapid drying without structural compromise. The choice is personal, but must respect the 22mm lug width specification.
Are aftermarket straps compatible with the Longines Legend Diver L3.674.4.50.9?
Yes, many aftermarket straps are compatible provided they respect the 22mm lug width specification. On milanostraps.it you will find a curated selection of leather, alligator, calf, rubber and NATO straps specifically calibrated for this width. Straps are customizable in length, initials and stitching thread, with 18-month warranty if handcrafted by the Casati Milano atelier.
How long does a leather strap last on the Longines Legend Diver L3.674.4.50.9?
Leather strap longevity depends on usage, maintenance and material quality. Premium vegetable-tanned leather offers 2-3 years of daily wear before replacement, developing pleasant patina during this period. First-grade alligator and calf guarantee 3-5 years. Lifespan extends if the strap is not exposed to constant moisture and is regularly cleaned. Rubber or NATO straps last longer in aquatic environments, requiring replacement every 4-6 years depending on intensity of use.
