The Orient Bambino RA-AC0028S30B is Version 7 in the larger 40.5 mm case: white dial, gold-tone stainless steel, brown leather strap, date at 3 o’clock. Orient’s in-house F6724 automatic sits inside — hand-winding, hacking seconds, about 40 hours of reserve — with a domed mineral crystal and an exhibition case back. Water resistance is 30 metres.
Orient lists this reference as Bambino Version 7 at 40.5 mm, not the compact 38.4 mm bracelet series. The face is still Classic: simple indices, vintage-leaning dome, no bezel. The gold-tone case and brown leather are the dress combination. See other Orient Classic / Bambino watches and the wider Orient watches Australia range.
Who it suits
Shirts, jackets, and evenings. White dial plus gold-tone steel reads more formal than a black dial on a bracelet. Forty millimetres is the traditional Bambino size; lug-to-lug is 46.5 mm, so it wears longer than the 38.4 mm Version 7. Thirty metres of water resistance is splash and rain only. The leather strap is not for swimming, and the mineral crystal will mark sooner than sapphire.
If you want a smaller steel-bracelet Bambino, look at RA-AC0M09E30B (green) or other RA-AC0M* Version 7 pieces. If you need 200 m and a bezel, that is an Orient diver, not this watch.
What you notice on the wrist
The white dial is the easy read. Gold-tone hands and indices sit on it without crowding. The brown leather strap (21 mm at the lugs) is the default dress finish; a buckle, not a deployant, keeps the back of the watch thin enough for a cuff. Thickness is 12.3 mm per Orient Watch USA — not a dress wafer, but typical for an automatic Bambino with a display back.
F6724 is the same family used across current Bambinos: 22 jewels, 21,600 bph, hand-wind from the crown, seconds stop when you pull the crown to set time. Wear it, wind it after a weekend off, and do not treat it as a sports watch.

Case dimensions follow Orient Watch USA for RA-AC0028S30B (40.5 / 12.3 / 46.5 / 21 mm). Some EU listings round diameter to 40 mm and thickness to 12 mm; we keep the manufacturer millimetre figures.
How it compares
Versus the 38.4 mm green bracelet RA-AC0M09E30B, this watch is larger, gold-tone, and leather. Same F6724, same 30 m, same dome. Pick this if you want a white-dial dress look and do not mind the extra millimetres. Pick the compact bracelet if you want steel and a shorter lug-to-lug.
Versus older 42 mm Bambinos, Version 7 at 40.5 mm is a modest step down, not the compact 38.4 mm cut. It still wears like a classic dress automatic, not a micro-watch.

Frequently asked questions
What movement does the Orient Bambino RA-AC0028S30B use?
Orient calibre F6724: automatic, with hand-winding and hacking seconds, about 40 hours of reserve, 22 jewels, 21,600 bph. The exhibition case back shows the movement.
What is the case size of the RA-AC0028S30B?
40.5 mm diameter, 12.3 mm thick, 46.5 mm lug-to-lug, 21 mm lug width. That is Version 7 in the larger case, not the 38.4 mm bracelet series.
Is the RA-AC0028S30B suitable for everyday wear?
Yes as a dress and office watch. Keep it away from water beyond rain and handwashing. Leather and a mineral crystal both need ordinary care — dry the strap, avoid knocks on the dome.

30 metres / 3 bar. Not for swimming, showering, or diving. The crown is push/pull, not screw-down.
Is the case gold or gold-plated steel?
Orient specifies a yellow-gold / gold-tone stainless steel case, not a solid gold watch. The strap is brown leather with a matching-tone buckle.
