There’s also authenticity in a “British” twin made by the Japanese, because Kawasaki’s Akashi factory built its own vertical twin in the Sixties, the W1.

For the first time collectors will be able to own a book that is just like owning the original document. It is faithfully reproduced to that level of detail. Not only is the publication a high quality copy of the original, the original manuscript's photographs are themselves high quality photos of each watch. The result.... a stunning 280 page color book of more than 4,000 individual Gruen watches.
