A little protection for your ordi Garmin Descent MK3i 51mm (compatible only with this model). In comparison to previous models, this one has been completely redesigned, taking also account of the watch integrated light. The protector is by default clipsed on the watch avoiding the use of bungees. It is still possible to use bungee if needed. The protector also include as an option an integrated and replaceable H9 tempered glass. This glass is part of the protector and does not adhere to the curved glass of the watch. The protector can be removed after the dive in a matter of seconds.
