TAG Heuer Aquaracer Professional 500 Date Dive Watch
Starting from 5.400 €The TAG Heuer Aquaracer Professional 500 Date pushes the Swiss house’s diver a notch further. Unveiled at Watches and Wonders 2026, it slots between the Aquaracer Professional 300 and the now-discontinued Superdiver 1000, with a sandblasted grade 2 titanium case measuring 42 mm, 500 metres of water resistance and a helium escape valve. Its automatic TH30-00 calibre, COSC chronometer-certified and offering seventy hours of power reserve, forms the model’s central technical argument. Released as two limited editions, one with orange accents and one with blue, each numbered to 1,500 pieces, it targets demanding divers and collectors alike, drawn to a dive watch that is light, legible and seriously built.
TAG Heuer Aquaracer Professional 500 Date dive watch
TAG Heuer holds a distinctive place in the world of the dive watch. The Swiss house built its reputation on the sports chronograph and the world of motor racing, but its line of divers dates back to the late 1970s. The Aquaracer collection traces directly to the Heuer reference 844 of 1978, a tool watch whose functional spirit still runs through today’s models. From this lineage, the brand has drawn six identity markers it has applied to the whole range ever since: unidirectional rotating bezel, screw-down crown, serious water resistance, luminescent elements, sapphire crystal and secure clasp.
The Aquaracer Professional 500 Date brings all of these together and pushes the dial further up the scale. It fills a gap left in the range between the Professional 300, designed for everyday use, and the 2022 Professional 1000 Superdiver, larger and now absent from the catalogue. The size stays reasonable, but the construction hardens: sandblasted titanium, DLC treatment on the bezel, a helium escape valve and a solid caseback engraved with the diving helmet, the collection’s signature motif.
The mechanics play a full part in this repositioning. The TH30-00 calibre, COSC chronometer-certified, comes from the Kenissi manufacture, which also supplies other houses known for their tool watches. Sold in two numbered limited editions, this Aquaracer presents itself as a genuinely contemporary diver, technical and aimed at enthusiasts of exclusive pieces.

The TAG Heuer Aquaracer Professional 500 Date dive watch
Unveiled at Watches and Wonders 2026, this Aquaracer occupies the space left vacant between the Professional 300, built for everyday wear, and the discontinued Superdiver 1000. Its case, 42 mm in diameter, borrows the earlier model’s format but executes it entirely in sandblasted grade 2 titanium, a choice that changes how the watch feels on the wrist. Complete on its metal bracelet, it weighs only 120 g, a remarkable figure for a diver capable of withstanding 500 metres of water resistance.
The dodecagonal unidirectional rotating bezel, treated in black DLC and fitted with a ceramic insert, handles dive-time tracking, while the screw-down crown and solid titanium caseback lock the whole package. A helium escape valve set at 10 o’clock rounds out the equipment, a marker of professional divers designed for ascents after saturation diving. Beneath the caseback engraved with the diving helmet, the collection’s visual signature, runs the COSC-certified TH30-00 calibre, an automatic beating at 4 Hz and offering 70 hours of power reserve. This movement, already used on the Superdiver, addresses reservations long expressed about the brand’s mechanics. The dial stays true to the line’s codes, with applied hour markers, generously luminescent hands and a magnified date at 6 o’clock that can be read at a glance, even underwater.
Two limited editions for lovers of exclusive divers
The model comes in two guises, sold at the same price and offered in parallel. The more demonstrative version pairs a lacquered black dial, an orange flange, rhodium-plated hands and hour markers filled with white Super-LumiNova, and a first quarter of the bezel in orange that stands out against the case’s matte black. The second plays a more restrained tune: a black dial with a wave-effect gradient, a blue seconds hand, a white flange with blue accents and the first fifteen minutes marked in blue on the polished ceramic insert. Each colourway is produced in a run of 1,500 pieces, a figure recalled by the engraving on the back of the case.
Both share the same sandblasted and fine-brushed grade 2 titanium bracelet, built on three rows, fitted with a micro-adjustment system and a double-safety-push-button deployant clasp with a diving extension, allowing the wearer to move from a bare wrist to a wetsuit without tools. The presentation follows the same utilitarian logic, the watch arriving in a black case with red clips accompanied by a professional dive light rather than a traditional box. Announced for April 2026, this Aquaracer appeals as much to divers seeking a light, standard-compliant instrument as to collectors drawn to numbered series and titanium cases.
TAG Heuer Aquaracer Professional 500 Date dive watch: titanium and 500 metres
This Aquaracer Professional 500 Date brings together a sandblasted grade 2 titanium case measuring 42 mm, a black DLC unidirectional rotating bezel with a ceramic insert, a screw-down crown, a solid caseback engraved with the diving helmet and a helium escape valve at 10 o’clock. Water resistance reaches 500 metres, the sapphire crystal receives a double-sided anti-reflective treatment, and the black dial combines applied hour markers, white Super-LumiNova hands and a magnified date at 6 o’clock. The automatic TH30-00 calibre, COSC-certified, beats at 28,800 vibrations per hour and offers 70 hours of power reserve. A titanium bracelet, a Pelican-style case with a dive light and a run of 1,500 pieces per colourway complete the package.
Movement
The watch is driven by the COSC chronometer-certified TH30-00 calibre, an automatic movement already used on the 1000-metre Superdiver and produced by the Kenissi manufacture. It beats at 28,800 vibrations per hour, or 4 Hz, a frequency that favours rate stability, and offers 70 hours of power reserve, enough to let the watch rest all weekend without needing to reset the time. The functions stay deliberately simple and useful for diving, with hours, minutes, seconds and date displayed.
Diameter and materials
The case measures 42 mm in diameter and is made of sandblasted grade 2 titanium, including the screw-down crown and the solid caseback engraved with the diving helmet. The black DLC rotating bezel with ceramic insert carries orange graduation on one version, blue on the other, while the helium escape valve at 10 o’clock is likewise made of DLC-treated titanium. The black dial, lacquered or gradient depending on the reference, is protected by a double-sided anti-reflective sapphire crystal. The result is a contained weight of 120 g including the bracelet.
Water resistance
The Aquaracer Professional 500 Date offers 500 m of water resistance, or 50 bar, a level that clearly places it among serious dive watches. This relies on a screw-down crown, a solid grade 2 titanium caseback and a helium escape valve at 10 o’clock designed to release gas built up during saturation dives. Tracking dive time falls to a unidirectional rotating bezel, while legibility in darkness comes from the applied hour markers and hands treated with white Super-LumiNova.
Accessories
The watch is fitted to a sandblasted, fine-brushed grade 2 titanium bracelet, built on three rows and equipped with a micro-adjustment system. It closes with a double-safety-push-button deployant clasp fitted with a diving extension, essential for fitting over a neoprene wetsuit. The presentation departs from the usual format: the piece arrives in a black Pelican-style case with red clips accompanied by a professional dive light, an ensemble that underlines the instrument vocation the model claims rather than only its collectible side.
Warranty
TAG Heuer covers the model with a five-year warranty, structured in two stages: two years granted at purchase, then three additional years after registering the watch with the brand. This extension therefore requires action from the owner, best done without delay to benefit from full coverage. Like any watch warranty, it covers manufacturing defects and not normal wear, impacts or work carried out outside the authorised network, a point that matters for a diver genuinely used underwater.
