An early Made-In-Japan Casio BP-100 (circa 1980s) with screw in type stainless steel caseback. Even the light source is not the illuminator-type (Casio has yet to develop illuminator technology back then) but the orange light built-in on the left of the LCD.
Mint, unworn, new-old-stock piece. New battery installed and all functions fully operational!
An interesting and lasting digital piece to wear or collect.
Jet black resin case with striking red and yellow buttons with yellow panel and steel sensor.
Water-resistant 50m.
Case diameter 45mm (diagonally across yellow button-to-yellow button) and durable resin strap 17mm inner lug width.
(Note: The serial number is digitally blotted out using MS Paint.)
