Seiko - 1973 SlideRule Calculator Chronograph 6138-7000

WHAT WE LOVE:

The Seiko Calculator Slide Rule Chronograph (Ref. 6138-7000) is a great example of 1970s design. This watch combines the robust 6138 automatic movement with a unique bi-directional slide rule bezel, making it both a tool and a statement piece for the wrist. Rare and highly collectible, this model represents Seiko's pioneering spirit during the golden age of chronographs.
