Personally, while I appreciate the 116xxx series of Daytona (& have no plans to sell mine, so do not ask), I have come to find them too large & blingy for daily wear. That said, if they are your cup of tea, I would opt for an early 116520 because they were produced without the ROLEXROLEXROLEX engraving on the flange on the case that runs perpendicular to the dial.Alternatively, for a bit less bling (still essentially the same size), try the previous (modified) Zenith-powered 16520.
As for reps, search out By-Tor's brilliant review of the 116520 rep &/or my perfect Daytona thread, & be aware of the inherent mechanical issues of the secs @ 6 7750 that powers the best modern Daytona reps.
