The 16 Holes case back is a first, as seen way before the Polaris. Calibre: Vulcain 120. Model: Cricket Nautical. Year of Manufacture: 1967. I consider as one of the most interesting Super Compressors, along with the Polaris, the UG and the Longines, and an unique watch in its category as it is the only one to associate an alarm and a decompression scale in a diving watch.
