You will love the vibrant colors and pristine shape of this massive, UNUSED SORNA world time slide-rule chronograph! Sorna was the firm of Mr Ernest Schneider who bought the Breitling name after Willy Breitling voluntarily closed his firm in the 70s due to illness. This watch measures a hefty 47mm. across and is new old stock (unused) sparkling condition with the rear case sticker still intact. All functions are operating smoothly (as they should) and the manual winding movement is accurate. You will not find a better example of this watch!
