The Orient Star Modern Skeleton RK-AV0135L represents the technical and aesthetic evolution of the Japanese manufacturer’s most iconic model. This edition optimizes its front architecture by increasing the openwork area to reveal more moving parts of the movement, blending visible engineering with the sparkle of its navy blue dial featuring a sunray iridescent finish.

At the heart of the timepiece beats the in-house F6F44 caliber, a mechanical movement offering a 50-hour power reserve that can be checked at a glance via the fan-shaped indicator at 12 o’clock. The dial is balanced by a small seconds sub-dial at 6 o’clock, which is larger than in previous versions, ensuring immediate readability beneath its highly transparent, anti-reflective sapphire crystal.

Its 41-mm case is crafted from SUS316L surgical-grade stainless steel, showcasing a seamless transition between mirror-polished edges and brushed surfaces. With 100-meter water resistance, anti-magnetic protection, and a screw-down crystal case back, it combines the mechanical precision of Japanese haute horlogerie with durability suited for everyday use.
