The Orient Helios RA-AG0028L10B pairs a deep blue gradient dial with an open-heart window so you can watch the balance wheel at work. At 40.5 mm it sits in classic dress-watch territory, yet the semi-skeleton layout and steel bracelet give it more presence than a plain three-hand Bambino.
If you want a Japanese automatic that looks sharp under a cuff and still shows real mechanical movement, the Helios is one of the more distinctive Orient Classic options we keep in stock. The gradient dial shifts from rich blue toward lighter tones as the light changes, which is why the collection is nicknamed Helios.
Why the RA-AG0028L10B works
- Open-heart drama without a huge case — 40.5 mm diameter, about 12 mm thick, roughly 46.5–47 mm lug-to-lug, so it wears closer to a classic dress watch than a sport piece.
- In-house open-heart calibre — Orient F6T22 (often listed as FT622): automatic winding, hand-winding, hacking seconds, about 40 hours power reserve, 22 jewels.
- Ready-to-wear bracelet — stainless steel bracelet with butterfly clasp; no strap swap required out of the box.
- Dress-appropriate crystal — domed mineral crystal over a clean blue dial with date.
Water resistance is 30 metres. That covers rain and hand washing, not swimming or showering. Treat it as a dress and office automatic, not a diver.

Frequently asked questions
What movement does the Orient Helios RA-AG0028L10B use?
It uses Orient’s in-house F6T22 open-heart automatic (also marketed as FT622). You get automatic winding from wear, manual winding at the crown, and hacking seconds for precise time setting, with roughly 40 hours of power reserve.
What is the case size of the RA-AG0028L Helios?
The case is 40.5 mm across, about 12 mm thick, with a lug-to-lug around 46.5–47 mm and 21 mm lugs. It wears as a mid-size dress watch on most adult wrists.
Is the Orient Helios suitable for everyday wear?
Yes for office, commuting, and dry daily wear. The steel bracelet and automatic movement make it practical day to day. Keep water exposure light: 30 m rating means splashes only, not swimming.
How is the Helios different from a standard Orient Bambino?
Standard Bambinos usually run closed dials on leather straps with calibres such as F6724. The Helios keeps Classic dress proportions but adds a blue gradient open-heart dial and ships on a steel bracelet with a butterfly clasp, using the F6T22 open-heart movement.
Does the RA-AG0028L10B have a date?
Yes. It has a date window in addition to the open-heart aperture on the dial.
