Learning About the Seiko Turtle Dive Watch
Introduction
The Seiko Turtle is one of the most famous and least expensive diving watches which are manufactured by Seiko. It was first released in 1976 and became popular because of its sound construction, unique design and reliable functionality. The watch is referred to as the turtle due to its cushion shape of the case which appears like a turtle shell.
Seiko Turtle was designed as a diving watch, however, as time went by it started to be worn by watch lovers and the general consumers. The Turtle is famous even nowadays as long-lasting, comfortable, and providing great value.
History of the Seiko Turtle
In the year 1965, Seiko started to make diving watches and the first was the 62MAS. In 1968, Seiko would again come up with another iconic diver, the 6105. In 1976, The Turtle was released and it became one of the most successful diving watches that were made by Seiko.
