The year 2017 will be remembered as a special one for all the folks at Greubel Forsey. For this year, they join an exalted rank of manufacturers – Patek Philippe, A. Lange & Söhne and F.P. Journe, among others – that have accomplished a grande sonnerie wristwatch. Ask any watchmaker worth his salt and he will tell you that the grande sonnerie is immensely complex, even more so than a minute repeater, which is why only a small handful of manufacturers have managed this feat.
The Greubel Forsey Grande Sonnerie though, is more than just a watch with a grande sonnerie – it also has a petite sonnerie and minute repeater function. The grande sonnerie chimes the hours and the quarters at every quarter hour, while the petite sonnerie chimes only the hours. The minute repeater chimes the time to the nearest minute on demand, unlike the grande et petite sonnerie which chimes en passant. Here we bring you the details and our thoughts on the Greubel Forsey Grande Sonnerie, a horological giant that reportedly took 11 years of research and development.
