Rolex Daytona Zenith 16520 X series inverted six

I am offering a very good Rolex Zenith Daytona 16520 in steel, with serial X901xxx, from around 1991. Watch has a mint MkIII Tritium dial with invertetd 6 and hands build in. Has a 78360 bracelet with 12 segments, 503 endlinks and claspcode N4 and is in excellent condition with no major wear and only moderate stretch. Case has been carefully polished in the past and shows also almost no signs of prior use, except some inevitable swirls. Watch has received an authorized Rolex service through AD Böckelmann, on January 08, 2018 and has obviously been barely worn since that time.
The Rolex Zenith Daytona take its nickname from the fact that it’s powered by a Zenith El Primero calibre 400 that has been adapted by Rolex in around 50% of the movement parts to call it then 4030.
A very nice package, with it’s 66.00.2 box, mooncrate outerbox, German Rolex Cosmograph booklet and Rolex Service card. It’s running on high amplitude within COSC specs, winds smoothly with no indication for a service withing the next years, nothing else to expect with a AD service only two years ago.
