This stainless steel Omega Seamaster chronometer-grade watch dates to 1949-1950 and is very uncommon. Finding these watches with a chronometer-grade movement is extremely difficult. Few of these watches were produced. Notice the early caliber 352 bumper automatic movement having adjustments for five positions and temperatures (chronometer-grade). This movement was recently cleaned and is working perfectly. The dial is two-tone with reflective Arabic numerals, raised steel arrow markers, Dauphine hands, and is all original. The correct Omega crown is installed. The steel and correct ref. 2577-8 34mm beefy lug case is without any major dings or flaws.
