Requiring ten patents and six years of development, F.P. Journe explains, "The grand-strike clockwatch is the most complex of horological creations. The greatest difficulty in its construction is to achieve full clockwatch capability from the limited energy available in a wristwatch without compromising on the sound and reliability of the chime."

F.P. Journe is relatively new the independent watchmaking world but he's become an overnight success since the 1999 inception. Comparisons to masters like 19th century watchmaker/inventor Abraham Louis Breguet and Antonio Stradivari (Stradivarius violins) are certainly piquing the interest of many. And within the insular & ravenous watch collecting world, there exist entire forums dedicated to his brand.
The Sonnerie is priced at 650,000 Swiss Francs with only four made per year (with a waiting list) but the rest of the Journe collection starts at $19,400 USD.
