VULCAIN Chronograph 70's - Blue

An underwater icon reimagined

The Vulcain Cricket Nautical is more than a classic diver's watch – it is a technical instrument with historical depth and a fascinating story. With its striking 42 mm stainless steel case and a substantial height of 17.35 mm, it embodies the robust presence expected of a professional diver's watch. Its carefully polished 316L steel case creates an elegant contrast to the functional orientation of this timepiece.

Design meets function

Behind the domed sapphire crystal, which is equipped with an anti-reflective coating, a semi-matte dial in deep black is revealed – featuring integrated decompression tables that are not only visually fascinating but also an essential aid in practice underwater. The polished silver hands and indices give the watch a subtle vintage aesthetic that still appears modern.

Mechanics with a signature

Inside the watch beats the manual winding caliber V-10, a complex movement with a total of 165 components. It is a classic alarm movement with a double barrel and the so-called Exactomatic regulation. The frequency is 18,000 vibrations per hour, and the power reserve of 52 hours underlines the endurance and precision of the movement. Particularly noteworthy is the alarm function – with a duration of approximately 20 seconds – which sounds reliably not only in the air but also underwater.

The sound of the deep

This audible alarm function is made possible by the so-called Triple Case Back – a three-part case back system that acts as a resonance chamber. This construction allows the alarm sound to remain perceptible underwater – a true unique selling proposition. Alternatively, the watch is also available with a sapphire crystal exhibition case back, adorned with Vulcain's stylized "V," allowing a view of the movement without sacrificing aesthetics.

Legacy of an adventure

The original Cricket Nautical emerged from a unique collaboration of three pioneers: Hannes Keller, a visionary deep-sea diver and mathematician from Switzerland; filmmaker and researcher Max-Yves Brandily; and certified diving instructor Arthur Droz. Together with Vulcain, they developed the first diver's watch that combined both a decompression table on the dial and an acoustic alarm function – a milestone in the history of watchmaking.

A moment of recognition

Particularly touching is Vulcain's tribute to Hannes Keller, who passed away on December 25, 2022. His legendary diving mission on November 3, 1966, off Toulon, where he reached a depth of almost 250 meters – with a Cricket Nautical on his wrist – was even witnessed by Jacques Cousteau himself. This watch was not just a tool, but a loyal companion on one of the deepest documented dives of its time.

Technology for connoisseurs

Two superimposed dials – one fixed, the other rotatable – form the heart of the decompression system. An additional screw-down crown at 4 o'clock allows the scale to be individually adjusted. Depending on the diving time and depth, the necessary decompression stops at 9, 6, and 3 meters appear in a rectangular window. A mechanical solution that still sets standards in its sophistication today.

Tradition and innovation united

The Vulcain Manufacture, whose origins date back to 1858, remains one of the most important houses in Swiss watchmaking. Its headquarters in picturesque Le Locle – in the heart of the Neuchâtel Jura – is not only historically significant but also a symbol of the craftsmanship that goes into each of its watches. The Cricket Nautical is a worthy heir to this long history – a combination of timeless technology and modern demands.

More than a watch

The Vulcain Cricket Nautical is not just a timepiece – it is an instrument for professionals, a collector's item for enthusiasts, and an expression of decades of engineering artistry. Its unique profile, its acoustic functionality underwater, and its deep-rooted history make it a true milestone. Whether as a reminiscence of past heroic deeds or as a tool for new adventures – this watch is ready for whatever comes next.
