Garmin MARQ Diver (Gen 3): a connected dive watch with no holes in the case
Since 2019, the MARQ collection has represented the top of Garmin's connected tool watch lineup. With the third generation, announced on 13 October 2026, the range welcomes a model designed for diving for the first time: the MARQ Diver. Grade 5 titanium, sapphire crystal, blue ceramic bezel, a dive computer with a depth gauge certified to 40 metres and nautical functions inherited from the Quatix make up its specifications. Its case has notably lost the holes for its pushers, replaced by induction-based controls, and its bezel no longer rotates. What a demanding diver will make of it remains to be seen, since the watch also makes notable compromises. It is priced at €3,150.
The MARQ Diver, the first diver's watch in a tool watch collection
When Garmin unveiled the third generation of its MARQ collection in Olathe, Kansas, on 13 October 2026, the brand lined up six watches: Adventurer, Athlete, Aviator, Commander, Golfer and a newcomer, the Diver, presented as the latest addition to the family. It takes the place of the MARQ Captain, which was exclusively focused on sailing in the previous generation. The Diver brings together in a single case two worlds that Garmin had previously treated separately, that of the Descent dive computers and that of the Quatix nautical watches, all within the refined styling typical of the MARQ line. Every watch in this generation can dive, but only the Diver makes that its reason for being.
A high-end lineage born in 2019
The MARQ collection was launched in 2019, and some observers regard the 2016 Chronos as its true ancestor. The second generation arrived in 2022. The third builds on the technical platform of the Fenix 9, from which it takes most of its core before adding its own functions. The MARQ watches share a common hardware base: grade 5 titanium for the case and a sapphire crystal to protect the screen. Garmin has also paid close attention to the watchmaking side with customisable digital dials inspired by famous watches, including World Timer, Panda and Flieger styles.
A case without holes, an answer to dive watches' weak point
The most interesting change for a dive watch enthusiast is almost invisible. The second-generation MARQ had five holes in its case to accommodate its pushers. On the Gen 3, all five holes have disappeared. A polymer wall now seals the side of the case, an inductive sensor placed behind it detects each press, and a small metal dome delivers a crisp click under the finger. Garmin justifies this choice with a well-known observation: on a dive watch, the crown and pushers are the usual point of failure. This architecture relies on nano-moulding, which bonds a glass-filled polymer to the titanium without a seam. The process slims down the case and creates a non-metallic window through which the GPS, LTE and satellite antennas can transmit.
A ceramic bezel that has stopped turning
On the Diver, the bezel keeps the look of a classic diver's watch but has given up its function: it is now a fixed ceramic ring. Immersion time is now tracked on screen, thanks to a 60-minute timer that can be started directly from the dial. For an enthusiast used to the rotating bezel, the break with the mechanical dive watch code is clear, but it makes sense on an instrument that already displays everything on screen. The ceramic is nonetheless far from mere decoration: it is coloured through the material, so the blue remains even if scratched, and its white markings are engraved before being filled with ink.

A dive computer on the wrist, from scuba to freediving
Underwater, the Diver behaves as a fully-fledged dive computer, with a depth gauge certified to 40 metres, while the case itself is rated water resistant to 100 metres. It covers single-gas scuba diving, freediving and snorkelling. Logging can start automatically from a depth of 1.5 m, GPS entry and exit points are recorded, and the watch warns of too rapid an ascent as well as when approaching the safety stop. Compared with the Fenix 9, it gains several dive-specific tools: global DiveView maps, which show depths and nearby sites, the NDL Aware function, a Gauge mode and an Apnea Hunt mode. Dive Readiness cross-references dive history and advises against intense training right after a dive.
A 47mm case built for a wetsuit
The case measures 47mm in diameter and 15mm thick and weighs 62 grams without the strap. A slightly domed sapphire crystal sits over the borderless 1.4-inch AMOLED screen, the largest ever fitted to a MARQ, capable of reaching 3,000 nits. Battery life reaches 18 days, or 7 days with the screen always on. The Diver is worn on a silicone strap fitted with a titanium deployant clasp, whose micro-adjustment offers 15mm of fine tuning, enough to go from bare skin to wetsuit thickness without undoing the whole strap. There is no metal bracelet option: it would interfere with the LTE and satellite antennas.
From the boat deck to the distress signal
On board, the Diver carries on the Captain's legacy. It takes over the sailing and navigation functions of the Quatix, with the exception of Boat Mode, and can control the autopilot and assist with tacking manoeuvres via Garmin's marine electronics. Like all Gen 3 MARQ watches, it integrates inReach connectivity: LTE calls, messages and weather via LTE or satellite, and SOS relayed to the Garmin Response centre, reachable day and night. A diver who has drifted far from the boat can thus raise the alarm once back on the surface. A speaker, microphone, LED light, TopoActive maps and an ECG app round out the equipment.
Can the MARQ Diver replace a dedicated dive computer?
For a recreational diver staying within the 40-metre limit, the Diver does the job. The more serious diver, however, will run into several gaps. The watch only manages a single gas and, above all, it does not offer the wireless air integration that the Descent models provide through their tank sensor, a surprising omission on a model named Diver and priced at €3,150 in France, or $3,100 in the United States. On the surface side, the satellite link requires a clear sky and does not work underwater; its functions remain considerably more limited than on other inReach devices, and they require an active subscription, billed at $9.99 per month after a 30-day trial.
Garmin MARQ Diver (Gen 3): a diver's watch that dares to seal its case
The mechanical dive watch has been built around a handful of components that have become almost untouchable: a crown, pushers, a rotating bezel. The MARQ Diver does not set them aside out of provocation, it reinterprets them with the resources of an electronics manufacturer. Removing the holes from the case means tackling the question that haunts every dive watch designer, that of long-term water resistance. Entrusting timekeeping to the screen means accepting that function takes priority over ritual. The wager has its limits, and a technical diver will continue to prefer a specialised computer. But in a world where the tool watch is defined first by what it allows you to do, the Diver is a reminder that a dive watch is not a fixed style: it is an answer, always provisional, to an environment that does not forgive carelessness.
