But in 2014, I was guided by nothing more than what I was after. link And I would eventually track down and purchase a GMT-Master II Batman (you can read my story link about that watch here). I write all of this preamble and personal meditation because I distinctly remember a time in Rolex fandom when it was basically Hulk vs. Batman when it came to hype models in the broader collection (sure the ceramic link Daytona too, but that was effectively unobtanium from the jump).

Taken together these details ensure that the FXD isn't ornamental or superfluous. It's a tool not a token. The FXD is a useful addition link to a link diver's link gear kit especially in diving situations that require low visibility navigation.
