Not only the 1965 memovox wasn't the first waterproof alarm watch, it wasn't even the first JLC waterproof alarm watch!, the facts was misquoted because of some mis-communications.
The first JLC waterproof alarm watch was actually the Deep Sea, a modele created especially for the US market and launched in 1961!
The Deep Sea watch was equiped by the calibre 815 Memovox and the number produced was around 1,000 pieces.
Thanks for your sharp observation, we need more members just like you...
