If you search for a serious mechanical dive watch, you will find plenty of options. If you search for one with a mechanical alarm that rings underwater, the field shrinks to almost nothing. That is what makes the Vulcain Nautical Heritage worth a closer look. It is a modern revival of a 1960s diving instrument, and it works as a tool, not just as a styling exercise.
This guide covers the watch's history, its key specifications, the four available configurations, and who it suits best.

This guide covers the watch's history, its key specifications, the four available configurations, and who it suits best.
What Is the Vulcain Nautical Heritage?
The Nautical Heritage (also called the Cricket Nautical Heritage) is a hand-wound Swiss dive watch from Manufacture Vulcain. It is built around the brand's signature Cricket alarm complication and adds a decompression scale to the dial. The version covered here is the Black Beige Patina, which pairs a semi-matte black dial with brown faux-patina indexes and polished silver hands. The look is vintage, but the watch is built to be worn and used.A Brief History of Vulcain: From 1858 to the Cricket
To understand the Nautical Heritage, you need to know where Vulcain comes from. Vulcain's story begins in 1858 in the Swiss Jura, founded by a pair of talented watchmakers, the Ditisheim brothers. The company later became the Fabrique Vulcain, and it earned recognition at the Paris World Fair for a Grande Complication watch, an early sign of its technical ambition.
The real turning point came in 1947, when Vulcain launched the world's first alarm wristwatch with a striking mechanism: the Cricket. This was a hard engineering problem. Watchmakers had struggled for years to fit both a delicate precision movement and an alarm mechanism into a thin wristwatch case.
The name is well earned. The original movement borrowed the resonance principle of the cricket: a second case back created a resonance membrane that produced a very loud, long-lasting alarm sound mechanically. That distinctive sound became Vulcain's signature.
The Presidents' Watch
The Cricket quickly found a famous audience. It earned the nickname "The Presidents' Watch" because Harry S. Truman and his successors Eisenhower, Nixon and Johnson all found it useful. A watch with a loud alarm that fits under a shirt cuff appealed to busy people, and that reputation still supports the brand today.
The Nautical Origin Story: A Watch Built by Divers, for Divers
Once Vulcain had mastered the mechanical alarm, it took the idea somewhere new: underwater. From the 1950s onward, the Le Locle brand also partnered with well-known mountaineering and maritime expeditions, so a dive-focused Cricket was a natural next step.
In 1961, Vulcain became the only watch manufacture offering a diver's watch with an aquatic alarm, one audible underwater. The Cricket Nautical came out of research by three specialists who shared a goal, a dive watch that could show no-stop dive times on the dial and also sound a real alarm telling the diver when to head for the surface:
Hannes Keller, a Swiss physicist and mathematician, occasional pianist and deep-sea diving pioneer
Max-Yves Brandily, an explorer and filmmaker
Arthur Droz, a nationally certified diving instructor linked to the C.I.A.S. (Centre d'Investigations et d'Activités Sous-Marines)
Together with Manufacture Vulcain, they developed what the brand describes as the first dive watch combining a built-in no-stop time system with an audible alarm, in a case water resistant to 300 metres.
Hannes Keller's 1966 Deep Dive
The watch has a record to its name. On 3 November 1966, in Toulon, France, Keller reached a depth of almost 250 metres with a Cricket Nautical on his wrist. Jacques Cousteau, already a legend, witnessed and validated the dive. Vulcain has paid tribute to Keller since his death on 25 December 2022, and the Nautical Heritage line is part of that legacy.
How the Underwater Alarm Works
The Triple Case Back is what makes the underwater alarm possible. It acts as a resonance chamber, carrying the sound of the alarm through the case so it can be heard below the surface. The Cricket Alarm Calibre V10 powers the alarm, which rings for about 20 seconds (give or take 5), long enough to get a diver's attention.
The same principle that gave the original Cricket its name is at work here, applied to diving.
The Decompression Scale: More Than a Diving Watch
Vulcain calls the Nautical Heritage a diving instrument, and the dial shows why. Two superimposed dials, one fixed and one rotating, are adjusted with a dedicated screw-in crown at 4 o'clock. Once you set the dive duration and depth, a rectangular aperture displays the stop times required at 9, 6 and 3 metres on the way back up.
The 42mm case is large enough to read these indications easily, which was generous for its era. Divers who work with no-stop tables will find it genuinely useful, and vintage enthusiasts will enjoy the functional dial layout.

Other Nautical Heritage Versions: Full Black and Black White Luminova
The Black Beige Patina isn't the only way to wear the Nautical Heritage. Vulcain's current catalogue also includes the Nautical Heritage Black White Luminova and the Nautical Heritage Full Black. All three share the same 42mm case, the Cricket V10 alarm calibre and 300-metre water resistance, so the choice comes down to character.
The Black White Luminova keeps the semi-matte black dial and decompression tables but swaps the vintage tones for white Super-LumiNova® markers and hands with a blue minute track. It has a crisper, more contemporary tool-watch look, with strong legibility in low light.
The Full Black goes the other direction. It has a matt black dial with gray printing and black Super-LumiNova indexes, and the case is black ion plated, for a stealthy monochrome finish. One practical note: the Full Black is not offered with the plexiglass crystal option, so you would choose it in sapphire.
In short, the Black Beige Patina suits vintage lovers, the Black White Luminova suits those who want maximum contrast and a classic dive-watch feel, and the Full Black suits anyone after something discreet and modern. Pricing on the collection page currently starts from CHF 4,200.
How to choose:
Sapphire offers scratch resistance and a crisp modern finish.
Plexiglass gives the warmer, softer look of vintage dive watches.
The steel Triple Case Back is the version that acts as the resonance chamber for the underwater alarm.
The open case back shows the stylised Vulcain "V" on a sapphire window. It is attractive, but if you plan to use the alarm underwater, the steel Triple Case Back is the sensible choice.
Who Is the Vulcain Nautical Heritage For?
- Divers who value a mechanical instrument and want a dive timer they can hear as well as see
- Vintage-watch lovers after 1960s character with modern reliability and a two-year warranty
- Collectors of complications looking for something more distinctive than a standard dive watch
- Enthusiasts who care about provenance, given the Keller and Cousteau story
About Manufacture Vulcain
Vulcain has come a long way since 1858, and the brand is very much alive. It was reborn and relocated to Le Locle, and it is now housed in a private mansion in the town regarded as the cradle of Swiss watchmaking. Its history includes the 50's Presidents' watch and the Imperial Gong, billed as the first tourbillon alarm watch.
The Cricket line keeps evolving. Earlier this year, Vulcain reinterpreted the Cricket with the Cricket Titan, a 100-piece limited edition using the in-house Caliber V14, assembled entirely at its Le Locle manufacture. The Nautical Heritage belongs to the same tradition of mechanical alarm watches made in-house.
