Nauticalia

This advanced Casio watch has a digital compass, barometer with 24hr history, thermometer, moon status indicator, tide range graph, countdown timer, stopwatch and five alarms. It can be switched between 12/24hr readouts, and has an automatic calendar (always reads the right day and date) and luminescent backlight. Many functions are assigned specific buttons for instant information, whilst the streamlined case reduces the chance of becoming caught up in clothing or rigging. It is water (to 330ft), shock and scratch resistant.
