About Tokyo Clock / Ricoh:

Tokyo Clock Manufacturing Co. was founded in 1920 and revived post-WWII in 1951, becoming Japan's second-largest domestic clock and watch producer, listed on the Tokyo Stock Exchange in 1962. The company ceased operations in 1984 following acquisition by Orient Watch. Ricoh was a respected Japanese watch brand competing alongside Seiko, Citizen and Orient.

Decimal stopwatches (100-division dial) are less common than standard 60-second stopwatches and are highly sought after by collectors and industrial history enthusiasts.

What you get:

✅ Ricoh stopwatch

✅ Original Tokyo Clock presentation box

✅ Original braided lanyard cord

A wonderful addition to any vintage horology or Japanese collectibles collection. Estimated age: circa late 1950s–1960s.
