The Orient Star Modern Skeleton RK-AV0130G is one of the Japanese brand’s most distinctive models, popularly known among enthusiasts as the “Joker” due to the expressive layout of its skeletonized dial. The mechanical cutouts at 9 o’clock and 2 o’clock, combined with the small seconds sub-dial at 6 o’clock and the power reserve indicator at 12 o’clock, recreate the appearance of a smiling face, lending the timepiece a unique visual dynamism.

Inside beats the in-house mechanical caliber F6F44, a robust movement equipped with 24 jewels, manual winding, and a seconds stop function for second-by-second time adjustment. The 50-hour power reserve is monitored in real time via the fan-shaped indicator at the top, while the anti-reflective sapphire crystal ensures a crystal-clear view of the contrast between the gold components and the dark case.

Its 41-mm stainless steel case features a black finish that extends to the bezel and the links of the solid bracelet, achieving an avant-garde aesthetic with a contemporary presence.

With 100-meter water resistance (10 ATM), anti-magnetic protection, and a screw-down sapphire crystal case back, this watch combines the craftsmanship of Japanese haute horlogerie with robust durability for everyday use.
