Product Information

This package pairs the Garmin Descent Mk3i 43mm dive computer with a genuine Garmin QuickFit 20mm band, so you have a spare band ready to go without hunting for the right part number. The Descent Mk3i is Garmin's air-integrated dive computer and smartwatch, available here in Bronze PVD Titanium with a French Gray Silicone Band or Carbon Gray DLC Titanium with a Black Silicone Band, both in the 43mm case size.

Underwater, the Mk3i runs SubWave sonar messaging, which sends preset messages to your buddies up to 30 meters away and can monitor tank pressure and depth for up to 8 divers within a 10-meter range. Pair it with Descent T2 transceivers (sold separately) and it tracks air pressure across up to 8 tanks, useful for multi-tank or team dives. The case carries a sapphire crystal lens, a diamond-like carbon coated titanium bezel, and a fiber-reinforced polymer body with a titanium rear cover, and it's rated for diving to 200 meters. Above the water it still runs as a full Garmin smartwatch: AMOLED touchscreen, built-in mapping, multi-band GPS, Garmin Pay, sleep score and insights, and training readiness and status tracking.

The included QuickFit 20mm band is Garmin's tool-free system: the band itself carries the hinge, so it slides into the lug and locks with a lever instead of a spring bar and pin pusher, and it's compatible with the Descent Mk3i 43mm. The QuickFit 20mm line comes in silicone, ComfortFit fabric in Short and Long lengths, leather, and heathered nylon, and the 3-piece dive sets ship with extension pieces so the same band can extend over a 7mm wetsuit sleeve. Swapping bands takes a couple of seconds and nothing on the watch has to come apart to do it.

Frequently Asked Questions

What is the Garmin Descent Mk3i dive computer?

It's Garmin's air-integrated dive computer and smartwatch, built for nitrox, trimix, gauge, apnea, apnea hunt and closed-circuit rebreather (CCR) diving. It has a dive water rating of 200 meters, an AMOLED touchscreen display, a sapphire crystal lens, and a DLC-coated titanium bezel with a fiber-reinforced polymer case and titanium rear cover. It also has SubWave sonar for sending preset messages to dive buddies underwater.

What band size does the Garmin Descent Mk3i 43mm use, and does the QuickFit 20 band fit it?

Yes. This bundle pairs the 43mm Descent Mk3i with the QuickFit 20mm band line, and the band's own compatibility list explicitly names "Descent Mk3i - 43 mm" as a fit.

Are Garmin watch bands interchangeable?

Within a matching QuickFit lug-width group, yes — QuickFit is a tool-free lever mount, so swapping a band takes a couple of seconds with no spring bar or pin pusher needed. The 20mm QuickFit line in this bundle fits a specific set of Garmin watches with 20mm lugs (including the Descent Mk3i 43mm), so it isn't a universal fit across every Garmin band or case size.

Does the Garmin Descent Mk3i have music storage?

Yes, per Garmin's feature listing the Descent Mk3i includes music storage.

Does the Descent Mk3i support air integration for tank monitoring?

Yes. Paired with Descent T2 transceivers (sold separately), it can monitor tank pressure and depth for up to 8 tanks using its SubWave sonar data network.

Can you buy Garmin watch bands separately?

Yes — the QuickFit 20 bands in this bundle are sold as genuine Garmin bands on their own; the listing is for the band only, the watch is sold separately (and included here as the bundle's other component).

What's included in this Descent Mk3i + QuickFit 20 Band bundle, and how does it ship?
