I dive with both a dive computer (when required for the depth
or nitrox) and a dive watch. I use the computer but always like the watch better. I have owned several over the years and used all for diving
. Casio's work perfect fine. Seiko's are of course very reliable.
My ultimate watch would be a Doxa of course...but out of your price
range (and mine).
A few years ago I discovered Invicta dive watches (and the name is just a funny
coincidence). They are absolutely outstanding Swiss watches. As well made as a ROlex or Omega, with equal material, workmanship and detail, but for less money
. I really love these watches and now have an automatic and a quartz one. Their top of the line dive watches are 25 Swiss ETA jewel movement automatics, screw down crown and sapphire crystals. Most rated to 200m depth
. These movements are the same ones used in the automatic Omega's and Rolex's...though those may be modified and more finely adjusted in order for them to be certified COSC...but in my experience, even the average 21 jewel Myota movement Invicta watches meet the COSC standard and are accurate to 2 sec per day...the 25 j swiss ETA movements are more accurate. I think you can get one online in the $300-400 range depending on model.
And one note about mineral vs sapphire crystals....I actually managed to crack a mineral crystal on a watch after a dive...probably dropped weights or a tank on it...never a problem with a sapphire crystal watch...or maybe I took more care....
Hope this helps
