39 mm Super-Compressor Diver

The Longines Legend Diver L3.764.4.90.2 is a 39 mm stainless steel watch powered by the automatic calibre L888. It features a bi-directional internal rotating bezel operated by the 2 o'clock crown, while the 4 o'clock crown handles time setting and winding. A scratch-resistant sapphire crystal protects the lacquered blue dial with applied Arabic numerals and luminescent arrow-pencil hands. The watch comes on a 20 mm blue nylon NATO strap with a signed stainless steel buckle.

Collectors wanting historic 300 m diver

This piece suits buyers who value the 1959 Super-Compressor heritage, dual-crown operation and a COSC-certified movement delivering 72 hours of power reserve at 25,200 vibrations per hour. It is not for wearers who require a date window on the dial, prefer a bracelet over a NATO strap, or need a case diameter larger than 39 mm.

300 m water resistance decides fit

The 300 metre rating is the single specification that determines whether this Legend Diver matches the buyer's intended use, from daily wear to professional diving. The screw-down crowns and solid case back secure that depth rating, while the 12.70 mm case thickness defines the wrist presence.

Questions about this item

How can I confirm the 39 mm Legend Diver is running correctly after I put it on?

The L888 calibre is a certified Swiss automatic chronometer beating at 25,200 vibrations per hour; a steady sweep of the seconds hand and consistent timekeeping within chronometer tolerances show it is working as intended.

What comes in the box with the L3.764.4.90.2 and what must I buy separately?

The watch ships new in its original Longines packaging fitted with the blue nylon NATO strap and signed stainless steel buckle; no additional strap or tool is required for immediate wear.

Which version of the Legend Diver should I choose if I want the 39 mm blue-dial model with a NATO strap?

The reference L3.764.4.90.2 is the 39 mm stainless steel Super-Compressor case with lacquered blue dial, internal rotating bezel, dual screw-down crowns and blue NATO nylon strap — exactly the specification described.
