■ Buyer's comment
SBJG021 is a watch that brings the "fun of spinning" to your wrist.
Turn the octagonal rotary bezel once. The feeling of operation alone brings back the joy of wearing a classic machine from the 1980s again.
The size of 37.0 mm in width fits both men and women, and the retro taste of digital coexists with a modern texture.
This is a masterpiece that adds "play" and "trust" to your everyday style without compromising on design or function. by Fujimuro
