Seiko “Pogue” style wrist watch from Jan 1970

All original parts, glass, and stainless steal band. In working condition, side buttons sticking a little, probably needs a good cleaning inside.

Fro Grok AI analysis of actual watch:

Serial and Model Number:

The serial number “01” (January 1970) places this watch among the earliest 6139 Pogues, which is a desirable trait for collectors. Early production models often have more value due to their historical significance.

The “6139-6002” model number matches the design seen on the front (yellow/orange dial, Pepsi bezel), reinforcing that the case and dial are likely original to each other.

Case Back Markings:

The “WATER 70M PROOF” and “STAINLESS STEEL” markings are correct for this model. Some aftermarket or refinished case backs might lack these details or have incorrect fonts, but these look consistent with originals.

The font and layout of the engravings match known examples of 6139-6002 case backs from the early 1970s.
