• Historic and refined proportions: a modest case measuring 38.4 mm in diameter and 44.0 mm from lug to lug—the classic dimensions of a traditional dress watch.
• A domed mineral crystal (Box Crystal) with an accentuated profile that lends visual warmth and evokes the classic atmosphere of mid-20th-century watchmaking.
• A screw-down case back with a transparent crystal reveals the decorated internal movement and the in-house rotor.
• Polished silver-tone hands and faceted, raised hour markers provide sharp contrast and immediate readability.
• Genuine brown leather strap with 20 mm quick-release pins for tool-free strap changes.
• Water resistance of 30 meters (3 bar / 3 ATM) for protection against everyday splashes and ambient humidity.
• Exclusive edition for the Japanese domestic market (JDM) with assembly and quality control “Made in Japan.”

The Orient Bambino RN-BB0001E pays homage to one of Japan’s most fascinating aesthetic traditions: the art of the Tamamushi (玉虫 or jewel beetle). For over a millennium, the iridescent elytra of this insect have been considered a symbol of distinction, eternal beauty, and protection, even adorning historic national treasures such as the famous Tamamushi-no-Zushi reliquary at Hōryū-ji Temple. This model translates that visual fascination into an emerald-green dial with an iridescent sunburst finish, capable of shifting from vivid green flashes to deep, almost black mossy hues depending on the angle of the light.

This rich color palette is framed by the acclaimed 38.4-mm-diameter case—a millimeter-precise reduction that returns the Bambino to the golden proportions of the classical era and allows the watch to slip seamlessly under a shirt cuff. Its domed mineral “Box Crystal” glass intensifies the dial’s vintage warmth, while its sleek 44-mm lugs ensure an ergonomic fit on any wrist.

Inside beats the in-house Orient F6524 automatic caliber, a reliable mechanism featuring manual winding, a seconds stop for second-by-second time adjustment, and a see-through case back that reveals the workings of the movement. Complete with a genuine leather strap featuring quick-release pins, it is a distinguished timepiece that blends the essence of traditional Japanese folklore with Japanese mechanical precision.
