This antique pigeon racing clock, specifically a model from Henry Martens and Company, was manufactured around 1920 in Belgium. These specialized clocks were used to time homing pigeon races. The clock housed a mechanism to record the arrival time of pigeons. The clock is housed in a wooden case, and contains a clock-stopwatch system for timing, along with a printing system to record the times. These clocks were essential tools in the sport of pigeon racing, and their complexity highlights the dedication and detail involved in timing these competitions.
