Seiko Chronograph 7018-7000 from 1971

For sale is a Seiko 7018-7000.

The success and popularity of the calibre 6139/6138 that debut in 1969 has largely overshadowed its 701x siblings that came out one year later.

Measuring just 5.9mm in thickness, the 701x calibres produced by the Daini factory in the 70s held the record of being the slimmest automatic chronograph in the world for 17 years before Frederic Piguet, created the calibre 1185 which had a measurement of 5.5mm.

On top of the fly-back function like the calibre 7017 family, the calibre 7018 has an additional 30 minute counter just like the calibre 6139.

Unlike the calibre 6139, only a handful of variants were produced with the calibre 7018.

The variant we have for sale here is nicknamed the "reverse one eyed panda" for obvious reasons.

The watch features a dark charcoal sunburst dial with recessed sub-dial, applied indices, and sunken date window gives the dial a greater sense of depth.

The sub-dials is finished with concentric circle that amplifies the viewing experience as light darts across it which complements the duo finishing of the dial the create an illusion of a stepped dial.

A dash of red is given to the tip of the chronograph second hand giving contrast to the otherwise monochrome dial.

The watch is in well worn condition with scratches seen across the case. The dial is free from aging other than the lume. Aging can be seen on the lume of the hour hand. The lume of the minute hand is absent due to aging. A brand new crystal has been installed for clarity.

The watch comes on its original bracelet that fits up to 7" wrist.

Serial number has been covered for privacy.
