The Seiko 5126-6010 is an unusual watch as it was designed and produced for the Japanese domestic market. Seiko had much hipper designs for their home market than they did for the rest of the world as we can see with this example, black dial and orange inner rotating ring.
Another unusual feature of this watch is the calibre 5126 movement. It’s an automatic winding, 23 jewel, 19,800bph movement with a day date complication. The movement architecture is quite different as there’s no pawl and transmission wheel autowind components, and the keyless work looks quite different too. This calibre has more in common with the Swiss method of using reverser wheels to convert the rotors movement into winding the mainspring.
This timepiece is part of their “Sports” range. When the “5” designation was introduced in the 1960’s it was a symbol of Seiko’s robust, dependable and unique watches which was meant to represent 5 different selling points; automatic winding, day and date displayed in a single window, water resistance, a recessed crown at the 4 o’clock position and a durable case and bracelet.
This example still has its original signed “Razor” bracelet and it’s in excellent condition. The watch its running as it should.
