Known as the first waterproof chronograph wristwatch, the distinct "Clamshell" case was patented in 1936 by Schmitz Freres & Co., and acquired in 1937 by Gallet. It’s a unique two-part compression case with a specialized flared crystal. The “Clamshell” case is also easily recognizable by the presence of four screws on the reverse side of the case, located under each lug.
The watch featured here is my Gallet MultiChron30M “Clamshell” with black “snail” dial, which was specifically produced for the battlefield as an artillery timing instrument. The watch was found in an old military trunk amongst other personal belongings of the previous owner.
I won the watch at an online auction back in May, 2016, and the watch was not in working condition when I won it, so I decided to send it to Gallet Service Department in the US right after winning it. With the help of Gallet Managing Director David Laurence, Gallet CEO Walter, and Gallet Chief Technician Lou, as well as the Gallet service team, the watch was properly documented by Gallet and underwent a “Museum Restoration” which includes servicing to restore full functionality and appearance while carefully preserving history and provenance. And I finally received the watch in metal for the first time in Australia, 11 months after winning the auction.
