Key Highlights
- Announced 9 November 2026: DIVEROID confirmed WatchDive will launch on Kickstarter in December 2026; the exact day is not yet set.

- Real dive computing: Bühlmann ZHL-16C decompression algorithm, depth readings accurate to ±0.1 metre, scuba and freediving modes, and Nitrox support.

What happened?
DIVEROID, a Seoul-based underwater technology company, announced WatchDive on 9 November 2026. It is a system — a waterproof housing, integrated sensors and the DIVEROID app — that turns a smartwatch many people already own into a full dive computer. The Kickstarter campaign opens in December 2026, with worldwide shipping planned.
The idea is aimed squarely at recreational divers. As DIVEROID CEO Jay Kim put it, many recreational divers only dive once or twice a year, yet a separate dive computer is a significant investment. DIVEROID is not new to crowdfunding — its 2019 Kickstarter raised US$522,097 — and it says its diving products are now used by more than 30,000 divers in 48 countries.
WatchDive Apple Watch dive computer: how it works
Most smartwatches cannot measure depth or water temperature, so they cannot work as dive computers on their own. WatchDive solves that with its own hardware: the housing carries DIVEROID pressure and water-temperature sensors, and the smartwatch displays the readings and runs the dive calculations through the app. No phone connection is needed underwater.
Before entering the water, a pressure-based seal check lets you test the housing's seal and catch O-ring problems early. A physical button switches WatchDive on and off, opens the digital compass underwater and sets heading markers. After surfacing, dive profiles sync automatically with the DIVEROID app, and you can import GoPro or Insta360 footage and match it to the depths and locations of your dive.

WatchDive vs Apple Watch Ultra and dedicated dive computers
Apple's Watch Ultra already has depth and temperature sensors and pairs with the Oceanic+ app — but that app charges a subscription, and the watch itself is a premium purchase. A dedicated dive computer needs no subscription, but professional units from companies such as Shearwater and Garmin cost roughly ten times as much as WatchDive's early-bird price, according to Tech Times.
| Option | What you need | Subscription | Cost |
|---|---|---|---|
| WatchDive + your watch | Housing + app | No, for core features | US$149 early bird; US$200 after |
| Apple Watch Ultra + Oceanic+ | Ultra watch + app | Yes, Oceanic+ app subscription | Premium watch + ongoing subscription |
| Dedicated dive computer | Separate device | No | Professional units cost roughly 10× WatchDive's early-bird price |
An app-only version is planned later for watches that already measure depth and temperature — Apple Watch Ultra, Ultra 2, Ultra 3 and Galaxy Watch Ultra 2 — but that is not part of this launch.
What Indian divers should know
There is no India-specific price or date: WatchDive is a Kickstarter product with worldwide shipping planned, so Indian divers can back it like anyone else. At US$149, the early-bird price works out to about ₹13,500 — far less than a dedicated dive computer, and a realistic accessory for anyone who already dives in the Andamans, Lakshadweep, Goa or Pondicherry with an Apple Watch or Galaxy Watch on their wrist.
Three honest caveats matter before you back it. First, this is crowdfunding, not a retail product: the December Kickstarter date and the January–March 2027 shipping window are projections, and crowdfunding always carries fulfilment risk. Second, the housing has been pressure-tested to 60 metres, but the recommended operating depth is 40 metres, and independent EN13319 certification was still in progress — the 60-metre test is not a certification. Third, check your exact watch model against DIVEROID's compatibility list first: the housing fits 38–49 mm watches, covers Apple Watch models except the Ultra series, and Galaxy Watch4 through Watch9. Wrist tech keeps getting more capable — Garmin's ECG app recently brought 30-second heart-rhythm checks to the wrist in India — but a dive computer is safety equipment, so treat any first-generation device with the caution your training demands.
Should you back it?
Price, availability and compatibility
| Tier | Price |
|---|---|
| Super Early Bird (first 100 backers) | US$149 (about ₹13,500) |

| Target retail price (reported) | About US$299 |
The Kickstarter campaign opens in December 2026 — the exact day has not been announced. Fulfilment is scheduled from January to March 2027. The smartwatch is sold separately, and the product carries a two-year warranty, with battery coverage of two years or 500 dives. You can join the launch alert on the official WatchDive site; signing up does not reserve the US$149 tier, which is limited to the first 100 backers.

FAQs
Can an Apple Watch be used as a dive computer?
Not on its own. Standard Apple Watch models lack depth and temperature sensors, so they cannot calculate decompression. WatchDive adds those sensors in its housing, while Apple Watch Ultra models can work as dive computers with the Oceanic+ app.
How much does WatchDive cost?
The Super Early Bird price on Kickstarter is US$149 (about ₹13,500) for the first 100 backers. After that the price rises to US$200, and the reported target retail price is about US$299. The smartwatch is not included.
Which smartwatches work with WatchDive?
The housing fits 38–49 mm watches. At launch it supports Apple Watch models except the Ultra, Ultra 2 and Ultra 3, plus Samsung Galaxy Watch4 through Watch9, including Classic, Pro, FE and Ultra variants. An app-only version for Ultra watches is planned later.
When will WatchDive ship?
The Kickstarter campaign launches in December 2026, with the exact day still to be announced. Worldwide shipping is planned, with fulfilment scheduled from January through March 2027 — those dates are projections, not guarantees.
Takeaway
WatchDive answers a real problem: occasional divers do not want to pay for a dedicated computer they use twice a year. At US$149 with no subscription, it is the cheapest route to proper Bühlmann-based dive data — as long as you know it is a first-generation Kickstarter product, not a certified retail device yet.
If you dive with a compatible watch, check your model against DIVEROID's compatibility list on the official WatchDive site and join the launch alert there — the US$149 tier is limited to the first 100 backers.
