Graham Dive Watches
As a numbered edition for 2012 Graham releases this new dive watch version of the Chronofighter called the Chronofighter Prodive Professional. Highlights contain a bold design, monopusher chronograph and 600 meters of water resistance. One cool thing that Graham seems to suggest is that the chronograph are able to be used underwater. If this is true, then the watch does in practice set itself apart from most diving chronograph watches that would have their water resistance ratings compromised if their chronograph mechanisms were used while the watch was submerged.
