Model: Seiko 7A36-7000 “Surf Timer” (1980s)
Overview: An obscure and highly distinctive member of Seiko’s famed 7A quartz chronograph lineup, the 7A36-7000 “Surf Timer” is a short-production model featuring a regatta countdown function. With its bold black and yellow color scheme, it stands out as one of the most visually striking and purpose-driven designs of the 7A series.
History: Produced for a brief period during the 1980s, the Surf Timer sits within Seiko’s legendary 7A family—widely regarded as the world’s first analog quartz chronographs. While most 7A models focused on traditional chronograph layouts, the 7A36-7000 introduced a regatta timer complication, making it a niche tool watch aimed at sailing and racing applications. Its limited production window has made it increasingly rare, especially in well-preserved condition.
