Will the Garmin Descent™ Mk2 fit my wrist?

How long does the Garmin Descent™ Mk2 battery last?
Between 15 hours and 50 days per charge, depending on the power mode. Garmin rates Battery Saver at 50 days and GPS and Music at 15 hours; the chart above lists all 7 modes.
How does the Garmin Descent™ Mk2 battery compare with other Garmin watches?

Is the Garmin Descent™ Mk2 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™ Mk2?
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™ Mk2's 52mm case, so they cover the same amount of wrist.
