Hamburg Chrono Regatta channels 70s regatta chronographs in primary red, yellow, and blue. The date window alternates numerals with colorful signal flags every two days. A polished–brushed steel case keeps the profile crisp. Inside, a mecha-quartz caliber VK64 by the Japanese manufacturer Seiko delivers a five-steps-per-second sweep—start/stop at 2, reset at 4 – with elapsed minutes at 9 and a 24-hour display at 3. On the back, engraved sailboats on the Alster tip the hat to Hamburg.
