The Orient Stretto RA-AK0311N30B is the sun-and-moon member of Orient’s 75th Anniversary Stretto line: a grey sunburst dial with day, date, and a day/night sub-dial, powered by calibre F6B24 inside a 41.5 mm steel case on bracelet. It is limited to 2,500 numbered pieces worldwide — aimed at buyers who want complication and anniversary provenance without jumping to Orient Star pricing.
If you have been comparing Orient sun-and-moon watches in Australia, this reference is the contemporary Stretto take: sapphire crystal, exhibition caseback with anniversary marking, and a full steel bracelet rather than leather dress furniture.
Why choose the RA-AK0311N30B
- 75th Anniversary limited edition — 2,500 individually numbered pieces with special caseback treatment.
- Sun-and-moon complication — a dedicated sub-dial shows day/night character alongside standard time.
- Day and date — practical calendar information for daily wear, not only a decorative moon disc.
- F6B24 automatic — Orient mechanical calibre with automatic wind, manual wind, hacking, roughly 40 hours reserve.
- Sapphire and steel — scratch-resistant front crystal, stainless case and bracelet, 50 m water resistance for ordinary daily use.
Dial layout
Grey sunburst dial with baton indices, luminous hour and minute hands, and a contrasting seconds hand for quick reading. Typical layout for this reference places the date near 3 o’clock, weekday indication on a sub-dial, and the sun-and-moon display as the visual centrepiece. The dial language is urban and architectural — part of the wider Stretto design story — with the vintage-style italic Orient mark used on anniversary pieces.
Movement: Orient F6B24
F6B24 is a self-winding mechanical movement with hand-winding and hacking seconds. Power reserve is about 40 hours. Jewel count is in the low twenties (commonly listed as 22). Wear it regularly or top up via the crown after a few days off the wrist. Hacking makes setting the time against a reference clock straightforward.
Case and bracelet
Stainless steel case about 41.5 mm across (excluding crown), roughly 13 mm thick, about 48 mm lug-to-lug, 22 mm lug width. Sapphire crystal protects the dial; the screw-down exhibition caseback shows the movement and anniversary engraving. Bracelet is stainless steel with a fold-over clasp. Water resistance is 50 metres — suitable for rain and sinks, not for swimming or diving.

How many RA-AK0311N30B watches were made?

What complications does the dial include?
Besides hours, minutes, and seconds, you get day and date displays plus a sun-and-moon (day/night) indication. It is a richer dial than the open-heart Stretto RA-AR0012N30B, which skips the calendar stack in favour of the skeleton window.

About 41.5 mm diameter, roughly 13 mm thick, about 48 mm lug-to-lug, 22 mm lugs. It wears as a modern full-size watch on most adult wrists.
Is the crystal sapphire?
Yes — sapphire on the front for better scratch resistance than mineral glass. The caseback is an exhibition display back.
Can I swim with the RA-AK0311N30B?
No. 50 m water resistance covers rain and hand washing only. Do not swim, shower with the watch on, or use it for water sports.
