The Orient Bambino RA-AC0031S30B is a 40.5 mm automatic dress watch with a clean silver dial, domed mineral crystal, and a leather strap. It belongs to Orient’s modern Bambino Version 7 line—the classic larger size—powered by the in-house F6724 automatic with hand-winding and hacking seconds.
If you want a mechanical watch that pairs with grey, navy, or black clothing without a busy dial, this silver reference keeps the Bambino’s simple layout and date window while the domed crystal adds a vintage-inspired side profile. The polished stainless case measures 40.5 mm across, about 12.3 mm thick, with roughly 46.5 mm lug-to-lug and 21 mm lug width for a balanced formal wear size.
