if you can look past the high price point, I think the Garmin Descent Mk3i might just be the best all-in-one smartwatch for divers you can buy today
so far, the display has proven to live up to its scratch-resistant claims
the only reason I can think of stopping me from moving over to Garmin fully is the fact that it still has a relatively clunky UI

Source: garmin.com (verified 2026-07-11) · corroborated by rippingitoutdoors.com. Garmin's official Nov 14 2023 press release (source) confirms the exact model — the 51 mm Descent Mk3i with built-in LED flashlight and air integration, a "200-meter dive-rated case," a touchscreen "AMOLED display," "up to 66 hours of battery life in dive mode" (footnote: estimate is for the 51mm Mk3i), and dive modes for single/multiple gas (nitrox, trimix), gauge, apnea, apnea hunt and closed-circuit rebreather — and states its US MSRP of $1,599.99 (silicone band) / $1,799.99 (titanium band). The Ripping It Outdoors retailer listing (corroboration) confirms the same 51 mm Mk3i at "$1,599.99" and supplies the model-specific numbers verbatim: 1.4" AMOLED display, 200 m dive rating, "Dive Mode: Up to 66 hours," "No Band: 77.8g" body weight, and a 3-axis compass. algorithm ("Bühlmann ZHL-16C") and batteryType ("Rechargeable, built-in lithium-ion battery") were taken verbatim from Garmin's official Descent Mk3 Series owner's manual specifications page; gasMixes and diveModes are left null because no fetched page prints an explicit programmable-gas count or a dive-mode count (only a prose list), and bluetooth=true reflects the explicitly documented Garmin Connect/Garmin Dive app sync and smart notifications.
