I would like to find a watch that I can use for both sailing and diving. I
would like a compass and barometer. An altimeter is cool too, but I could
do without. A count-down timer would be great. As far as diving, all I
need is a bottom timer and durability. I don't do mixed-gas, I don't
(intentionally) do decompression dives.

Does anyone have suggestions on a good watch?

I love some of the Suunto watches, but there is nothing that fits the bill
as described above. The closest thing I can find is the Observer. It is
water resistant to 100m (330ft), has a compass, barometer and altimeter.
Unfortunately, the manual says "this is not a dive watch, the buttons should
not be used when diving."

Has anyone out there used the Observer or similar Suunto watches for diving?

None of their dive watches feature compasses or barometers

Thanks,

Brien
