Harry Winston Project Z12 Limited Edition 42mm Automatic Watch Never Worn W/Box and Papers (1 of 300) - This Harry Winston Project Z12 watch is a fascinating timepiece with extraordinary details, with a design that is all about concentricity and symmetry. This watch features a Zalium case measuring 42.2mm in diameter and 11.27mm in height. The durable, corrosion-resistant, and lightweight Zalium is the brand's choice of high-performance alloy, and is made of zirconium and aluminum. The dial is inspired by Manhattan's great bridges and is protected by a domed sapphire crystal. At the edge of the dial is the disc for the date, next to the hour and minute rings divided by a large blue "bridge." The red-filled arrow hands create an illusion as if it traces a circular trajectory when they are actually non-overlapping and move in a semi-circular manner only. When the hands reach the half end, the retrograde feature jumps back. This avant-garde timepiece is powered by the 35-jewel Calibre HW3306 automatic winding movement that operates at 4 Hz and has 332 parts. The watch is fitted with a calfskin strap with a denim-like design and rubber lining. This model is limited to 300 units only. This timepiece has never been worn and comes with papers, accessories which include cufflinks and a pen, and the manufacturer's box. Ref. # OCEAHR42ZZ001
