Why consider it

The olive-green dial adds interest to a restrained three-hand design. Sapphire and battery-powered timekeeping make this a sensible alternative to the green Tsuyosa for someone who prioritizes convenience over a visible mechanical movement.

The tradeoff

The bracelet needs sizing, and the simple dial gives you no stopwatch or second time zone. Choose it for everyday timekeeping rather than extra tools.
