The Orient Star Avant-Garde Skeleton RK-AV0A03B reinterprets open-worked haute horlogerie from a contemporary technical and sporty perspective. Designed for the Japanese domestic market (JDM), this model stands out for its architectural dial with a deep black finish, structured in two overlapping layers: a lower base with a honeycomb pattern and an upper layer with cutouts inspired by mechanical gears, achieving a striking three-dimensional depth without compromising readability.

Powering the watch is the in-house Orient Star F6F44 caliber, a mechanical movement that provides a 50-hour power reserve, which can be checked instantly via the analog indicator at the 12 o’clock position. The dial balances its design with a small seconds sub-dial at 6 o’clock and a direct view of the balance wheel at 9 o’clock, all protected by a high-purity sapphire crystal with an anti-reflective coating.

Its 42.6-mm stainless steel case features a solid, angular design with a lug-to-lug width of 49.2 mm, harmoniously complemented by a premium leather strap.

With a water resistance of 100 meters (10 bar), a screw-down crystal case back, and top-tier Japanese craftsmanship, this watch combines the visual appeal of micro-mechanics in motion with versatility for everyday wear.
