I am kind of a watch freak...I only rock autos but keep in mind they can be expensive to service. Take for instance a Rolex Submariner (which is a classic, iconic dive watch) runs about $6K new but you can snag one used for about $3-$4k...however if you send it to Rolex for the 10 year service it will cost you $1k++ for a complete service. I have been through about 38 watches in the past year (I am a cronic flipper) and I have settle on one in the last few months. Take a look at Doxa if you are looking for a dive watch. They have mod ETA 2824 swiss automatic movements which are relatively inexpensive to maintain. The Doxa divers come in 42mm and 44mm and are tanks. I love mine. New they run $2400+ but you can snag a nice used one for $1200! You can always flip it if you buy used and not lose any $$$. Check out watchuseek.com they have many references, photos, and reviews. I know you will find something you like!
