Here's a quick description of the Monaco Piece d'Art, by Nic Foulkes, writing in GQ Britain -- https://www.gq-magazine.co.uk/watches/article/tag-heuer-monaco-50th-anniversary.

Foulkes lists the following five features of the watch --

• first, it is new old stock (right down to the instruction manual);
• second, the movement has been disassembled and reworked to haute horlogerie standards, including polished angles and all that;
• third, it has been upgraded from 17 jewels to 20;
• fourth, the caseback has been opened (purists will be relieved that the disc of steel was kept and comes with the watch); and
• fifth, it probably works better than the original (the Cal 11, while revolutionary in that it was a self-winding chronograph, lacked in performance, the date change was a terrible drain on a very small rotor and the crown was at nine o’clock).
