Garmin Descent Mk3 43mm Dive Computer Smartwatch - Stainless Steel


Description

The Garmin Descent Mk3 is an advanced dive computer and smartwatch engineered for divers who demand the best both underwater and on land. Sized for smaller wrists at 43 mm, it combines a brilliant 1.2" AMOLED color display with a sapphire lens and a 200-meter dive-rated case to handle everything from recreational dives to serious technical descents. With support for multiple dive modes - including nitrox, trimix, gauge, apnea, apnea hunt, and closed-circuit rebreather - it gives serious divers the data they need on every dive.

Above the surface, the Descent Mk3 transforms into a fully capable multisport GPS smartwatch with preloaded topographic and SkiView maps, robust health monitoring, and smart connectivity features. Garmin's DiveView color maps with bathymetric depth contours and over 4,000 dive sites help you discover and navigate new locations right from your wrist. Whether you're planning a dive, logging a surf session, or chasing a running PR, this watch is built to keep up.

FAQ

What is the difference between the Descent Mk3, Mk3i, and Mk3i with T2?

The Descent Mk3 is the standard advanced dive computer and smartwatch. The Mk3i adds air integration, allowing you to pair with Descent T2 transceivers (sold separately) for tank pressure monitoring and diver-to-diver messaging via SubWave technology. The Mk3i & T2 bundle includes both the Mk3i watch and the T2 transceiver, so no additional purchase is necessary to use air integration features.

Is the Descent Mk3 suitable for both recreational and technical diving?

Yes. The Descent Mk3 supports a full range of dive modes including single gas, multiple gas, nitrox, trimix, gauge, apnea, apnea hunt, and closed-circuit rebreather. This makes it appropriate for recreational divers as well as more advanced technical divers who work with multiple gas mixtures.

Can I use the Descent Mk3 as a regular everyday smartwatch?

Absolutely. When you're not diving, the Descent Mk3 functions as a full-featured GPS smartwatch with health monitoring, music storage, smart notifications, contactless payments via Garmin Pay, and support for dozens of sport and fitness activity profiles ranging from running and cycling to tennis, skiing, and team sports.

How does the Dive Readiness Tool work?

The Dive Readiness Tool is a Garmin-first feature that analyzes lifestyle factors including your recent sleep quality, exercise load, stress levels, and jet lag indicators to give you an assessment of how prepared your body is for a dive. It's designed to help you make more informed decisions about when to dive, not to replace professional dive training or medical judgment.

Does the 43 mm Descent Mk3 support QuickFit band swaps?

Yes. The 43 mm Descent Mk3 is compatible with QuickFit 20 mm watch bands, making it easy to swap between silicone, leather, metal, or nylon bands to suit your style or activity.

Can two Descent dive computers be synced together as backup devices?

Yes. The Setup Sharing feature allows two compatible Descent dive computers to seamlessly synchronize dive settings such as gases, conservatism levels, and alerts before a dive. This means either watch can serve as a fully interchangeable backup without the need for manual entry on both devices.
