Rolex Daytona Steel 16520 Porcelain Mk1 Dial Box and Papers

The first and the greatest of the steel Zeniths…

Today we are excited to be offering an example of arguably the most desirable 16520 – the Porcelain ‘Floating’ Mk1. The watches are known as ‘Zenith Daytonas’ due to the fact that the watches had a modified Zenith movement.

This example features the glossy lacquered white dial with five lines of text, with the COSMOGRAPH line ‘floating’ from the rest of the text. A ‘Floating’ R-Serial steel 16520 is a special watch but the much rarer porcelain version takes this watch up to another level. This is a true connoisseur’s watch! King of the Zenith Daytona's.
The dial is in stunning original condition.

The watch is fitted with the correct Mk1 ‘200’ bezel in great condition. The case is also in good, healthy condition. Having the correct movement number batch is also very important with these watches and this example has a movement number 13xxx which is correct. The original solid link Oyster bracelet, ref 78360, is in good condition with a clasp stamped ‘M 6’ and 503 endlinks. Inner and outer boxes, USA papers and Cosmograph booklet will accompany this Daytona and the modified Zenith movement has been fully serviced by our watchmaker.

Our Service

Each vintage timepiece is individually selected and carefully inspected by our team of experts. After we buy a watch it is mechanically inspected and fully checked by our watchmaker. If necessary, the movement will be fully serviced and tested to ensure it is running to our exacting standards.

We will always describe the watch as fully as we can in our sales texts. Our zoomable images are of the highest possible quality and form an important part of each watch’s description. We will never hide or cover up any element of any watch we sell.

Key to our unparalleled service is Fedex Priority shipping, fully insured. Once you have received your watch, we encourage you to inspect it thoroughly. If you are not 100% satisfied, please let us know. We offer a 14 days return policy. Simply return the watch to get a full refund of the original purchase price.

Our Warranty

We offer a one-year warranty on the mechanical function of the watch, starting from the day of purchase. We do not guarantee the waterproof nature of any (vintage) watch, unless expressly made in writing. Therefore, our warranty will not cover any damage done to the case and/or movement by water or moisture entering the watch. Our warranty does not apply to accidental damage or mishandling of your watch and does not extend to the bracelet, case parts (including pushers, winding stem, crown and bezel), watch glass, dial and hands.
