Kari Voutilainen came to the public eye with the creation of his “Observatoire” wristwatches, based on a Peseux 260 ebauche. A few years later, in 2008, he once again used another emblematic chronometer movement, this time based on the incredible Longines 360.

The Longines 360 caliber was completely devised from the ground up with observatory competitions in mind - it was a rectangular movement with a cutting edge (for the time) high frequency of 36,000 VPH, which subsequently won numerous prizes at the Neuchatel Observatory trials. With a total of 498 Bulletins de Marche, calibre 360 claims the most number of successful submissions of any wristwatch-sized chronometer calibre between 1959 and 1967!

Being movements made for competition, the aesthetics were put aside. That is where Voutilainen’s genius came to play - he disassembled each component and meticulously hand-finished them with beveling, perlage, gilding and frosting, each to the highest levels of visual and technical perfection possible. Furthermore, the Guillaume balance was fitted with a Breguet overcoil and Grosmann internal curve for maximum precision.

Housed in a large white gold rectangular case with lugs reminiscent of Voutilainen’s tear drop lugs the watch has a regulator type dial layout with hours indicated via a central hand, hours at 12 o’clock and seconds at 6 o’clock.

According to Voutilainen around 22 Chronomètre 27 pieces in both white and pink gold were made.
