OMER MIK1 Freediving Watch – Back Cover with Casing and O-ring OMER # R10054 Back Cover with Casing and O-ring New computer expressly designed to meet freediving needs. Easy to use, this computer features all functions of the most modern digital watches (time, date, chronograph, countdown timer, daily alarm, dual time) and a dive mode that provides all the information (depth, dive time, water temperature). Dive mode activates automatically to about 1,5mt depth and resume when returning to the surface. MIK1 stores up to 100 dive records. The data stored for each single dive are: Sequence number of the dive, date and time, water temperature, duration of the dive and maximum depth. MIK1 features a long rubber wrist strap that allows use with a thicker wetsuit. A shorter strap is available as spare. We highly recommend to complete the battery replacement by a certified Omersub dealer to ensure its waterproofness and warranty.
