The Orient Stretto RA-AR0012N30B is a 75th Anniversary limited edition built for people who want a contemporary automatic with real mechanical theatre — not another plain three-hand dress watch. A grey semi-skeleton dial and open-heart window show the F6S22 movement at work, while a slim 40.8 mm steel case and matching bracelet keep the watch wearable for everyday office and weekend use in Australia.
Only 2,800 pieces were produced worldwide, each with individual numbering and anniversary caseback detail. If you are comparing open-heart Orient models or shopping a numbered Stretto in Australia, this reference is the grey-dial steel bracelet version with sapphire up front and an exhibition back.
Why the RA-AR0012N30B stands out
- True limited run — 2,800 numbered pieces for Orient’s 75th anniversary, not an open production colourway.
- Semi-skeleton dial — grey finish with an open-heart aperture so you can watch the balance and gear train without going full skeleton.
- In-house style automatic — Orient calibre F6S22: automatic winding, manual wind, hacking seconds, about 40 hours power reserve, 24 jewels.
- Everyday durability — flat sapphire crystal, stainless steel case and solid-link bracelet, 50 m water resistance for rain and hand washing.
- Wearable case geometry — 40.8 mm width, about 10.9 mm thick, 48 mm lug-to-lug, 22 mm lug width — balanced for most adult wrists.
Design and dial
The grey dial uses modern wedge-style indices and a small-seconds layout that keeps the open-heart window as the focal point. Architecture-inspired detailing (bar and arch motifs on the Stretto line) gives it a city-contemporary look rather than classic Bambino dress cues. Hands and markers are designed for clean day-to-day reading; the exhibition caseback shows the decorated movement and anniversary marking.
Movement: Orient F6S22
F6S22 is a mechanical automatic calibre with hand-winding and hacking (the seconds hand stops when the crown is pulled for precise setting). Expect roughly 40 hours of reserve when fully wound. Accuracy is in the typical Orient mechanical band for this class; wearing it daily or giving it a few crown winds after a weekend off keeps it running smoothly. There is no date complication on this open-heart Stretto — hours, minutes, and small seconds only — which keeps the dial uncluttered around the skeleton window.
Case, crystal, bracelet
Stainless steel case, push-pull crown, screw-down exhibition caseback. Front crystal is sapphire for scratch resistance in daily wear. The steel bracelet uses a fold-over clasp with push-button safety. Lug width is 22 mm if you later prefer a leather or rubber strap from aftermarket options.

Who it suits
Ideal if you want a modern Orient automatic with visible mechanics, a steel sports-dress hybrid bracelet, and anniversary provenance. It pairs with smart-casual tailoring, dark denim, and clean sneakers. Collectors who already own Bambino or Kamasu pieces often add a Stretto open-heart as the “show the movement” option in the same brand family.

Frequently asked questions
What movement does the Orient RA-AR0012N30B use?
Orient calibre F6S22: automatic winding with manual wind and hacking seconds, about 40 hours power reserve and 24 jewels. It is a mechanical movement — no battery.
Is the RA-AR0012N30B a limited edition?
Yes. Orient produced 2,800 individually numbered pieces for the brand’s 75th anniversary. Expect anniversary engraving detail on the exhibition caseback.
What is the case size of the Stretto RA-AR0012N30B?
About 40.8 mm diameter, 10.9 mm thick, 48 mm lug-to-lug, with 22 mm lugs. It wears as a modern medium watch rather than an oversized diver.
Does this Stretto have sapphire crystal?
Yes — flat sapphire on the front. The caseback is exhibition (display) with a crystal window over the movement.
What is the water resistance?
50 metres (5 bar). Fine for rain, hand washing, and daily wear. It is not a dive watch — avoid swimming, showering under pressure, and water sports.
Does the RA-AR0012N30B have a date window?
No. This open-heart anniversary reference focuses on hours, minutes, and small seconds around the semi-skeleton aperture. If you need day/date plus sun-and-moon, look at Stretto references such as RA-AK0311N30B instead.
