The Longines Legend Diver is one of those watches that, over time, has come to occupy a category all its own. It has never been the most extreme diver on the market, nor the one most associated with military or professional imagery. Its strength has always been quieter: a sophisticated technical approach, extremely balanced proportions, and an instantly recognizable aesthetic personality built around the rotating inner bezel and the famous “super compressor” case.
This is also why the Legend Diver managed to make it through the heritage revival season so well. While many brands were chasing vintage as a stylistic exercise, Longines already had a design in its catalog that was born in a surprisingly modern way.
With the new Legend Diver 59, reference L3.795.4.59.9, the house goes directly back to the origins of the collection, recovering the language of the 1959 model with a level of fidelity rarely seen in operations of this kind. The 42 mm case, black grainé dial, bidirectional inner bezel, and Milanese bracelet reconstruct the aesthetics of the historic model, while the automatic caliber L888.6 with silicon balance spring, COSC certification, and ISO 6425 homologation bring everything back into a fully contemporary dimension.
Curious? Let’s find out in detail along with what made him famous in the past.
Before the Legend Diver: Longines and the construction of the modern diver
To truly understand the historical weight of the Legend Diver, one must go back to the years when Longines began to develop its expertise in waterproof watches.
The company was already producing waterproof timepieces in 1910. In 1937 it introduced the first chronograph with waterproof pushers, a patent officially registered the following year. Then in the 1940s came collaboration with the United Kingdom Hydrographic Institute to make watches for Royal Navy divers.
It is important to put this period in context. Professional diving was still building its technical language, and diving instruments were far from the standardization we know today. Longines therefore found itself working in a pioneering phase of diving watchmaking, contributing directly to the development of solutions that would later become fundamental to the industry.
In 1958 the company introduced the Nautilus Skin Diver, waterproof to 120 meters and equipped with a bracelet adjustment system designed to be used over a wetsuit. But it was the following year that Longines really defined its identity in the diver world.
1959: the first true Legend Diver is born
Reference 7042 from 1959 still represents one of the most interesting diver of its generation.
Longines in fact chose a different path than most of its competitors. Instead of using a traditional external bezel, he introduced a bidirectional internal rotating bezel graduated to 60 minutes, controlled via a second screw-down crown positioned at 2 o’clock.
The solution had a very specific technical rationale: to protect the bezel from accidental shocks, sand, and inadvertent manipulation during diving. The inner bezel was actually not a first for Longines. The brand had already developed this system in 1936, but the Legend Diver was the maison’s first true professional diver to use it so centrally.
The watch was built around a 42 mm Super-Compressor case that was water-resistant to 120 meters. The Super-Compressor technology represented one of the smartest solutions of the time: by increasing the external pressure, the case back was progressively compressed against the seals, thus increasing the watertightness of the watch as the depth increased.
Inside worked the Longines automatic caliber 19AS.
From reference 7594 to Royal Australian Navy
In 1963 Longines further evolved the design by introducing the reference 7594.
The case remained 42 mm, but water resistance was gradually increased to 200 meters in later versions. The movement used was the automatic caliber 290, while the overall layout of the watch remained true to the original identity of the model.
In 1974 came one of the most fascinating versions of the entire Legend Diver genealogy: the model developed for the Royal Australian Navy.
Here Longines increased water resistance to 300 meters and introduced the automatic caliber 633.1 with date display. The watch retained the bidirectional inner bezel and the Super-Compressor architecture, but with a decidedly more professional and technical approach.
The return of the Legend Diver
After decades of relative absence, Longines brought the Legend Diver back into the collection in 2007 with the reference L3.674.4.56.2.
It was also an important moment for the market. The heritage revival was starting to become central to the watch industry, but the Legend Diver looked different than many reinterpretations of the time. More credible, less constructed, mainly due to the fact that the original design already possessed a striking modernity.
Then in 2020 came the bronze version, reference L3.774.1.50.2, equipped with the automatic caliber L888.5.
However, the decisive step came in 2023 with the 39 mm reference L3.764.4.50.0. This model introduced ISO 6425 certification and COSC chronometer certification on the entire assembled watch, marking a clear qualitative leap in both technical and construction.
The Legend Diver 59 in detail
The new Legend Diver 59 now represents the most complete synthesis achieved by the collection. The stainless steel case measures 42 mm in diameter by 12.85 mm in thickness, with a lug-to-lug distance of 50.10 mm and a distance between lugs of 22 mm. The proportions remain extremely faithful to the historic model, but the execution is fully contemporary.
The black grainé dial is one of the most successful elements of the entire timepiece. The matte texture dialogues perfectly with the indexes and Arabic numerals treated with Super-LumiNova “Light Old Radium.” The spheres also directly echo the language of the original model.
Above the dial we find a sapphire box crystal with black metallic treatment and multilayer anti-reflective coating. A key detail to preserve that visual depth typical of vintage diver with domed acrylic glass.
Also particularly successful is the choice of the new Milanese mesh bracelet. Longines avoided an overly massive interpretation, opting instead for an extremely refined construction, complemented by a folding clasp with a double safety system and integrated micro-adjustment.
On the technical side, the Legend Diver 59 uses Longines automatic caliber L888.6, an exclusive 25,200 vibrations per hour movement with 21 jewels and 72 hours of power reserve.
The presence of the silicon balance spring and advanced non-magnetic components enables the watch to achieve ten times greater resistance to magnetic fields than the ISO 764 standard.
The entire watch is also COSC chronometer certified.
Even more important is the ISO 6425 certification, with water resistance guaranteed to 300 meters and tests carried out at a pressure 25 percent higher than the stated value. It is a detail that distinguishes the Legend Diver 59 from many contemporary heritage diver watches, which are often more focused on vintage aesthetics than real technical substance.
Conclusions and price
The strength of the Legend Diver 59 probably lies in the way it manages to escape the more predictable dynamics of the market it refers to.
Many modern divers try to look as vintage as possible. That’s why the Legend Diver 59 avoids stylistic excesses, invasive faux aging, and overly aggressive reinterpretations. It remains true to the 1959 proportions, the cleanliness of the dial, the centrality of the inner bezel, and the elegance that has always distinguished the collection.
On the technical side, the work is also impressive. ISO 6425 certification, 300-meter water resistance, caliber L888.6 with silicon balance spring, COSC certification, and even the €4,050 price tag keep the Legend Diver in the territory of authentic professional diver, preventing the model from being perceived as a mere nostalgic operation.
And this is perhaps the most interesting achievement Longines has made: having updated one of its most iconic watches without altering its character. The Legend Diver 59 continues to be what the original model was back in 1959: a technical diver designed with almost dress sensibility, still able to stand out in a crowded segment precisely because it speaks a different language.
