Orient RA-AK0312S30B Stretto Sun And Moon Automatic Bracelet Watch - W29112
Ref. RA-AK0312S30B
Sits in Orient’s upper tier here — more premium than three quarters of the Orient watches we list, which start at £159.
Price range £159 to £440 across 47 Orient watches in stock.The Stretto line is where Orient explores what an in-house automatic can do beyond telling the time plainly. This model adds a sun-and-moon day/night indicator alongside an off-centre day sub-dial, arranged asymmetrically across the white dial in a way that gives the layout genuine character without sacrificing legibility — the kind of complication that reads clearly at a glance rather than requiring study. The F6B24 is Orient's own calibre, built and regulated in Japan, and it comes with hacking and manual winding — practical courtesies that cheaper movements omit. Forty hours of power reserve and an exhibition caseback mean you can see what you are dealing with. At 48mm lug to lug the fit will suit average to larger wrists well, and 13mm of thickness keeps it from stacking too heavily under a cuff. The two-tone bracelet carries gold PVD accents that mirror the dial's warmth, and the dual push-button deployment clasp holds securely without fumbling.

Learn more about Orient
Orient began in 1950 as Tama Keiki, successor to a Tokyo watch business Shogoro Yoshida had started in 1901. It became Orient Watch Company the following year and set out to do something few companies attempt: build complete mechanical movements in-house, at prices aimed at ordinary buyers.
That is still the point of the brand. Orient designs and manufactures its own calibres rather than buying Swiss ébauches, which is why an Orient automatic can cost less than a quartz watch from a fashion label while containing a movement the company made itself.
The Bambino made the case to a wider audience — a domed-crystal dress automatic at a price that embarrassed a lot of more expensive watches — and the Kamasu and Mako divers did the same for tool watches.
Orient Star sits above the main line, with higher finishing, power-reserve indicators and in-house calibres of greater complexity.
The company became a subsidiary of Seiko Epson in 2009 and remains one, which gives it manufacturing depth while leaving the identity distinct from Seiko's own.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How long does it run for when it's not worn?
About 40 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
22mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 48mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's.
