It's no secret that Zenith Daytonas are amongst the fastest appreciating Rolex's of the last 20 years. This example would have been on of the first to feature the sub-dials with the large, highly legible 'straight 6' counters. In absolutely superb 'like new' condition, this 16520 even retains the original green holographic and is complete with its original Rolex box, punched warranty certificate and booklets.
