Still retaining its original green holographic sticker on the caseback, this “A-series” Zenith (retailed in Oct 1999) is in fantastically crisp condition and comes as a perfectly complete set, with its original Rolex box, punched warranty certificate, original instruction booklets, swing tag, calendar card and wallet. The final variant of the legendary 16520 Zenith Daytona, with all the upgrades paving the way for the 116520 with a Luminova dial, solid end-links on the fliplock bracelet.
