This Tag Heuer Aquaracer 500M Calibre 5 43mm Dive watch is the best watch i think from Tag Heuer Aquaracer,The water resistance is up to an impressive 500 meters. I know there are a lot of 1000m dive watches out there, but really? Is that necessary. While there will inevitably be quartz versions of the new Aquaracer line, the first models all have automatic mechanical movements. Powering the watch is of course the Tag Heuer Calibre 5 movement.

The steel case is 43mm wide being 48mm including the crown. Pretty wearable, even with the large aggressive looking crown.
