Long Description

The Orient Star Layered Skeleton RK-AV0B12E is a masterpiece of contemporary Japanese engineering and design. This limited edition of just 400 pieces for the Japanese market captures the relaxed and luxurious atmosphere of coastal resorts through a textured mint-green dial of exceptional beauty. Its dial stands out for its sophisticated layered construction that emulates haute couture textiles, incorporating a semi-skeletonized window in the shape of a paisley motif that reveals the steady beat of its balance wheel.

At the heart of this timepiece beats the in-house F6F44 caliber, a robust, precise automatic movement finely decorated with rhodium-plated bridges and an openworked rotor visible through the display caseback. True to the Orient Star identity, the dial features a power reserve indicator at the 12 o’clock position that allows you to monitor the mainspring’s power reserve of over 50 hours, accompanied by a separate seconds sub-dial at the 6 o’clock position.

Designed to withstand daily wear without losing an ounce of distinction, the watch features a double-curved sapphire crystal that eliminates visual distortions and ensures impeccable readability under any lighting conditions thanks to its anti-reflective coating. Its 41 mm case offers perfectly balanced proportions on the wrist, complemented by water resistance of 10 bar (100 meters) and JIS Class 1 magnetic resistance. The set is delivered in a special box with complete documentation and a gray leather strap that completely transforms the character of the timepiece.
