Graff Diamonds has unveiled the world’s most valuable transformable timepiece “The Fascination”, a £27.3 million transformable watch, says a report. The most expensive watch is exhibited at Graff’s Baselworld stand, located at Hall 1.1, Stand D51.

The Fascination is a one-of-a-kind bracelet-cum-watch, encrusted with a mind-boggling 152.96 carats of Graff’s finest white diamonds, adds a report. The Fascination’s transformability comes courtesy of a central 38.13-carat, pear shape diamond graded as D Flawless. It is the carefully crafted internal mechanism due to which, this stone can be removed from the bracelet and fitted into a bespoke ring shank. A diamond watch face can then be inserted in its place, making the Fascination one of the most expensive three-in-one jewels ever created, with a value of around $40 million (£27.3 million).
