Vintage NAKO NA-807 Calculator Digital Watch – Fully Working Retro 1980s

Rare vintage NAKO NA-807 digital calculator wristwatch from the 1980s.

Classic retro design reminiscent of Casio CA-53W, featuring a working LCD screen and fully functional calculator.

All buttons respond properly, and time/date functions operate correctly.

The inner electronics are clean and original, showing board marking Ver.1 907 (III) — a genuine production version of this rare NAKO model.

The case and strap are in good overall condition; the Levi’s metal buckle is a later replacement but fits perfectly.

Perfect collectible piece for vintage watch collectors or retro gadget enthusiasts.

Condition:

 • Fully working: time, date, and calculator functions tested.

 • Clean PCB, no corrosion or oxidation.

 • Minor cosmetic wear from age.

 • Battery included (newly replaced).

 • Strap with Levi’s buckle (non-original).

Notes:

This is a rare 1980s digital calculator watch.

Comparable Casio models (CA-53W, CA-500) sell for $60–120 in working order.
