SEIKO ~71's 5 SPORTS Speed ​​Timer Cal.6139A~

Introducing the 1971 Seiko " 5 Sports Speed ​​Timer Cal.6139A ".

 Seiko 5 , which was born with a durable mainspring, shock resistance function, calendar notation, automatic winding, and water resistance, recorded an explosive hit mainly among young people and office workers at the time.

From its release in 1963 to 1970 , various models were announced as a series of 5 , and it exists as one of the representative models of domestic watches.

The 5 sports speed timer introduced this time is a second chronograph with in-dials on the top and bottom.
As the world's first self-winding chronograph, it is a model with historical value that will be engraved in watch history.

The design is also distinctive, and the solid case is commonly called " UFO case" because of its unique appearance.
The dial has a matte black base with a colorful color scheme such as silver, yellow, and orange, giving it a sporty design.

The condensed appearance of various information such as the logo, in-dial, and day-date gives the impression of a cockpit instrument panel.

The installed movement is Cal.6139A , self-winding with 21 jewels.
Seiko's unique winding mechanism "magic lever" method is adopted, and the structure is as simple as possible, and by reducing the number of parts, it is easier to maintain than chronograph movements of other companies.

In addition, the "vertical clutch" mechanism used in this machine boasts such perfection that it was later adopted by other manufacturers.
As the world's first, it is a movement packed with Seiko's unique ideas and technical capabilities at the time.

The size is 48mm long, 44mm wide, and 15mm thick, giving it a sense of volume.

The unique shape and colorful colors of the UFO case give it a great impact on your hands, so it goes well with casual styles such as shirts and T- shirts.
The design goes against the simplicity of current watches, but it's a design that can't be seen now, so it's a piece that makes you feel fresh.
