OmegaThis Omega Speedsonic f300 Hz, widely known by the collector nickname "Lobster," is a vintage wristwatch from the mid-1970s. It features a distinct stainless steel integrated bracelet with wide links resembling a crustacean's tail.
The case measures 43mm by 43mm and has a thickness of 14.5mm. The dial is black with a mirrored finish, featuring chronograph sub-registers and a day-date display. Internally, the watch is powered by the battery-operated caliber 1255, an electronic tuning fork movement oscillating at 300 Hz. The auction report notes that the watch has been recently serviced and is in overall good condition, though the hesalite crystal exhibits minor surface wear.
The case back is secured by screws and bears the raised Seamaster emblem.
