Seiko Yacht Master 7A28-7090

The Seiko Yacht Master 7A28-7090 is a very rare and highly sought-after chronograph model among collectors that Seiko produced in the early 1980s. Although the name "Yacht Master" is generally associated with Rolex, Seiko also used this name for a short time on this model. This watch stands out with its unique design and mechanism that reflects the technological innovations of the period. One of the most important features that makes this watch special is the 7A28 caliber quartz movement it contains. When this movement was introduced in 1982, it was the world's first analog quartz chronograph movement. This was a major technological breakthrough for the time. The fact that it had a very short production period between approximately 1982 and 1985 makes this watch even rarer. To summarize briefly; The Seiko Yacht Master 7A28-7090 is a rare and collectible model that has an important place in Seiko's watch history. It has the world's first analog quartz chronograph mechanism, a unique design and features specially designed for sailing races.
