Hi,

The observer is No diving watch:

Ascent/Decent will not work - the observer is based on air atmosphers - under water is quite different (33 feet = 1 standard atmospher)- (same reason a dive watch won't give you altitude)

Compass - will not work (atleast with enough reliability to use it, and likely not at all)

Waterproof - yes - to the recommended depth. The watch will not rust or corrode

Timer - The Observer buttons are not designed to be used underwater - risk is low, but it is not what it was designed to do. Also - most dive timers start when you enter the water and stop when you leave. You run the risk of forgetting to start it, stopping it during the dive, or forgetting to turn it of afterwords - but otherwise it would work.

	Suunto Observer - Click for more info The shock-resistant Suunto Observer is a tool built for outdoor challenges, but its timeless design makes it wearable in any situation. The Observer is 1/3 smaller in both diameter and width than the first generation Suunto Watches (Vector, Altimax, etc). It also features a chronograph, which previously was only offered in the Navitech but is now discontinued.

	Compass Compasses are sensitive, absolutely crucial instruments to precision navigation. The earth's magnetic field, inclination, and your longitude and latitude all influence the horizontal plane of a compass needle. As a result, compasses are balanced for different geographical zones. Suunto Compasses overcome this limitation to traditional compasses by using a simple 'Two Zone System'. With a Suunto Compass, the only 'balancing zones' are the northern and southern hemispheres. In addition to this innovation, certain Suunto Compasses come equipped with useful features like luminous needles and marks, centimeter/inch scales, magnifying glasses, clinometers, sighting notches, and more.
