The Orient Bambino RA-AC0M09E30B is Version 7 of the Classic line: the familiar domed-crystal dress face, cut down to a 38.4 mm stainless steel case, with a green dial and a matching steel bracelet instead of leather. Date sits at 3 o’clock. Inside is Orient’s in-house F6724 automatic — hand-winding, hacking seconds, about 40 hours of reserve — visible through the exhibition case back.
The size is the reason this generation exists. Many older Bambinos sit around 40.5–42 mm. Version 7 was shortened so the watch clears a shirt cuff more easily and sits better on a smaller wrist without looking toy-like. If you already like the Bambino layout and want metal on the wrist, this reference is the green-dial bracelet option.

Who it suits
Office days, evenings, and quiet weekends. Thirty metres of water resistance covers rain and handwashing, not swimming. The domed mineral crystal is part of the vintage look; it will pick up marks sooner than sapphire, which is normal for this collection. There is no rotating bezel and no heavy lume — the watch is meant to stay simple.
If you need a steel sports watch that can go in the water, look at an Orient diver such as Mako 40 or Kamasu. For a leather-strap Bambino in a similar compact case, compare other RA-AC0M* Version 7 colourways on the Classic page. The blue bracelet sibling is RA-AC0M10L30B if you want the same case with a cooler dial.
What you notice on the wrist
Green on a small steel case is the whole personality. The dial is easy to read in normal indoor light; the domed crystal adds a bit of vintage depth without turning the watch into a costume piece. The bracelet keeps it in the “shirt and jacket” lane more than a brown leather strap would. Lug-to-lug is 44 mm, so it does not overhang most adult wrists the way a 42 mm dress watch can.
F6724 is a workaday Orient calibre: 22 jewels, 21,600 bph, hand-wind if it has sat still, hacking seconds when you set the time. It is not a high-beat chronometer. Wear it daily, wind it when it stops, and treat 30 m as splash resistance only.

How it compares
Versus a 40.5 mm leather Bambino (for example RA-AC0028S30B), this watch is shorter on the wrist and dressed in steel. Same F6724 family, same 30 m rating, same domed mineral crystal. Choose 38.4 mm + bracelet if you want a smaller, more “daily metal” Bambino; choose 40.5 mm + leather if you want a more traditional dress look and a gold-tone case.
Versus Kamasu / Mako, this is not a tool watch. No sapphire, no 200 m rating, no bezel. It is a Classic dress piece that happens to wear a bracelet.

Frequently asked questions
What movement does the Orient Bambino RA-AC0M09E30B use?
Orient calibre F6724: automatic, with hand-winding and hacking seconds, about 40 hours of power reserve, 22 jewels, 21,600 bph. You can see it through the exhibition case back.
What is the case size of the RA-AC0M09E30B?
38.4 mm diameter, 12.5 mm thick, 44 mm lug-to-lug, 20 mm lug width. That is the compact Version 7 case, not the 40.5 mm Bambino.
Is the RA-AC0M09E30B a good everyday dress watch?
Yes for office, commuting, and evenings. The steel bracelet makes it less fussy than leather in heat. It is not for swimming or heavy knocks. Treat the mineral crystal as something you will eventually polish or live with light marks.
What is the water resistance of the RA-AC0M09E30B?
30 metres / 3 bar. Rain and washing hands are fine. Do not swim, shower, or dive with it. The crown is a simple push/pull, not a screw-down.
Does the green Bambino come on a leather strap?
This SKU is the stainless steel bracelet version. Other Version 7 colourways use leather. If you prefer a strap, you can change after purchase; the lug width is 20 mm.
