Rarest of the Rare

Frances Devialet, which is revolutionising high-definition audio with oval speakers, has joined hands with legendary watchmaker Ulysse Nardin to create a limited edition of 85 Striking watches, which they describe as enhanced audible experience worn on the wrist. The watch rings on hour and half-hour on command and not only allows a person to see the time but also hear it. Devialet engineers have redefined each step in the chain of audio signals sent from Ulysse Nardins mechanisms to deliver the best-ever performance on a striking watch, 85 dB to 100mm. The fully polished 43 mm titanium case amplifies the sound and extends its resonance to 85 decibels.
