Quick take: The Orient Bambino Version 4 RA-AC0P01E10B is a 42 mm automatic dress watch with a green dial, domed crystal and in-house F6724 movement — a colour-led Bambino for people who want classic dress proportions without a plain black or white face.
Bambino is Orient’s best-known dress family in Australia: domed crystal, simple dials, accessible automatic movements. Version 4 references like RA-AC0P01E10B keep that formula and add a richer green dial with gold-tone hands and markers. This guide covers specs, sizing, water resistance limits, and how this green V4 sits next to smaller Bambino generations and open-heart Helios models.
Orient Bambino RA-AC0P01E10B specs
| Spec | Detail |
|---|---|
| Reference | RA-AC0P01E10B (Bambino Version 4) |
| Movement | Orient calibre F6724 automatic (hand-wind, hacking) |
| Power reserve | Approx. 40 hours |
| Jewels / rate | 22 jewels, 21,600 bph (typical for F6724) |
| Case | 42 mm stainless steel; about 11.8 mm thick |
| Crystal | Domed mineral |
| Dial | Green with gold-tone hands and markers; date |
| Strap | Leather, commonly 22 mm |
| Water resistance | 30 m (splash / rain only — not for swimming) |
F6724 is Orient’s modern dress-workhorse automatic: self-winding, manual winding when the watch has sat still, and hacking seconds for precise setting. That is more owner-friendly than older non-hacking Bambino calibres many people remember from earlier generations.
Size and wear: is 42 mm too big for a dress watch?
On paper 42 mm sounds large for “dress.” In practice Bambino cases are shaped to wear shorter than many sports watches of the same diameter, and the domed crystal softens the profile. Still:
- Wrists ~16.5 cm and up: 42 mm V4 usually looks balanced.
- Smaller wrists: consider later compact Bambino lines around 38–40.5 mm (for example current smaller Classic pieces) if you want more cuff clearance.
- Thickness ~11.8 mm: fine under a shirt cuff for most people; not a dress ultra-thin.
If you are undecided between green V4 and a white or champagne smaller Bambino, start with wrist photos against a 40–42 mm watch you already own. Our broader Orient Bambino Australia buying guide walks version and sizing choices in more depth.
Green dial: when it works
Green with gold-tone hands is less formal than silver-on-white and less severe than black. It pairs well with brown leather, navy and earth-tone clothing, and still passes in smart-casual offices. Under office LEDs the dial can look deeper than in sunlight — that is normal for saturated green sunburst or gradient finishes.
If you want maximum formality for black-tie adjacent events, a white or silver Bambino remains the safer default. If you want one dress watch that does not look identical to every other three-hander at the table, RA-AC0P01E10B is the more distinctive pick.
Water resistance and daily use
30 m on a dress watch means rain and hand washing — not pool laps, not beach swimming, not showering as a habit. Treat gaskets and the crown with respect; screw-down crowns are not the point of this design language. For swimming and surf, look at Orient’s dive-oriented models (Kamasu / Mako family) or dive watches with 100–200 m ratings instead.
Daily care is simple: wind a few clicks if the watch stopped after a quiet weekend, set the time with hacking, and keep the leather strap dry. Mineral crystal can scratch; a soft cloth and common-sense desk habits go further than polish kits.

What movement is in the Orient Bambino RA-AC0P01E10B?
It uses Orient’s in-house automatic calibre F6724 with hand-winding, hacking seconds and roughly 40 hours of power reserve.

No. 30 metres water resistance is for splashes and rain only. Use a proper dive or sports watch for swimming.
Is the RA-AC0P01E10B good for small wrists?
The 42 mm case can work from about mid-size wrists upward, but smaller wrists often prefer ~38–40.5 mm Bambino variants. Try comparable sizes or measure lug-to-lug if you are unsure.
How does Version 4 differ from older Bambinos?
Version 4 pieces like RA-AC0P01E10B typically use the modern F6724 with hand-wind and hacking, in a 42 mm dress case with a domed crystal — an update on earlier Bambino proportions and calibres.
