Orient Stretto Day & Night Watch RA-AK0312S30B

The Orient Star Mechanical Moon Phase RA-AK0312S30B represents the ultimate expression of lunar complications in Japanese mechanical watchmaking. The white dial features sophisticated radial texturing that reflects light creating depth and elegance. Applied golden indices contrast magnificently with the matching golden hands, while the upper subdial displays the days of the week in a perfect circle. The moon phase complication unfolds in the lower subdial, where golden sun and moon dance against a deep blue background, recreating the celestial cycle with poetic precision.

The golden bezel framing the sapphire crystal adds warmth to the two-tone ensemble, while the date window at 3 o'clock completes the calendar functions of this sophisticated timepiece. The two-tone metal bracelet combines polished steel links with golden details on the center links, creating perfect visual harmony with the case. Every detail has been carefully designed to offer exceptional legibility and lasting aesthetic appeal.

At the heart of this watch beats an in-house automatic calibre, developed specifically to handle calendar and moon phase complications with precision. The movement offers a generous power reserve that keeps all functions active for days without wear. Through the transparent sapphire caseback, one can admire the decorated automatic rotor and traditional Japanese finishing of the movement, testimony to the art of Japanese watchmaking.

Orient Star was born in 1951 as the premium line of Orient Watch, one of the last Japanese watch manufactures that develops and produces its own mechanical calibres. Each Orient Star watch is hand-assembled at the historic Akita factory, where master watchmakers with decades of experience individually adjust each complication. This artisanal tradition makes each piece a testament to the excellence of Japanese mechanical watchmaking.
