Descent™ Mk2i — Frequently Asked Questions
Will the Garmin Descent™ Mk2i fit my wrist?
The Garmin Descent™ Mk2i looks balanced on flat wrist widths of roughly 55–74mm (about 14.7–19.8cm circumference). Drag the slider above to check it against your own measurement.
What size band does the Garmin Descent™ Mk2i take?
26mm. Any 26mm strap fits, so you are not limited to Garmin's own bands — look for a quick-release fitting if you want to swap without tools.
How long does the Garmin Descent™ Mk2i battery last?
Between 15 hours and 50 days per charge, depending on the power mode. Garmin rates Battery Saver at 50 days and GPS + Music at 15 hours; the chart above lists all 8 modes.
How does the Garmin Descent™ Mk2i battery compare with other Garmin watches?
At 16 days in everyday use it ranks #90 of the 257 Garmin watches in our database — the top 35% of the range. The full ranking, including GPS and power-saving figures, is on our Garmin battery life comparison.
Is the Garmin Descent™ Mk2i thick for a 52mm watch?
At 17.8mm, middle of the pack for thickness at this width. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Garmin Descent™ Mk2i?
Rogbid Model R, Zeblaze Vibe 5, Omega Seamaster Planet Ocean Ultra Deep Professional, Seiko Prospex Diver SRPA79K1 Stainless Steel / Black all sit within half a millimetre of the Garmin Descent™ Mk2i's 52mm case, so they cover the same amount of wrist.
