Detailed and Persuasive Description

Cutting-Edge Engineering: The Architecture of Time

The Orient Star Avant-garde Skeleton RK-BZ0001S is a piece that redefines the boundaries of design and technology in watchmaking. Created for the enthusiast seeking a bold and contemporary expression, this watch not only displays the time, but also exposes the mechanical artistry that makes it possible.

The Inner Revolution: Silicon Escapement

At the heart of this piece beats the F8F64 calibre, a self-winding movement that introduces a silicon escapement to Orient Star for the first time. This technological innovation, reserved for high-end watchmaking, reduces friction and improves resistance to magnetism, ensuring exceptional long-term accuracy and reliability. With an extended power reserve of 60 hours, this watch is always ready for action.

A Three-Dimensional Dial

The dial is a visual spectacle. Its complex two-layer structure has been calculated to create a seamless transition to the visible movement. The upper plate, with the hour markers, contrasts in colour and finish with the lower plate, creating a fascinating interplay of depths and dimensions. Each component is designed to offer a clear view of the intricate mechanical dance beneath.

Absolute Clarity and Luxurious Finishes

To ensure an unobstructed view, the watch is equipped with a sapphire crystal with ‘Super Anti-Reflective’ (SAR) treatment on both sides, which eliminates 99% of reflections to the point that the crystal seems to disappear. The robust stainless steel case (SUS316L) combines brushed surfaces with the legendary ‘Sallaz’ mirror polish, a craft technique that creates incredibly sharp edges and a distortion-free shine, demonstrating an extraordinary level of finish.

Key Features

High-End Movement Cal. F8F64: Japanese-made automatic movement with a 60-hour power reserve.

Silicon Escapement: A first for Orient Star, it ensures greater precision, efficiency and durability.

SAR-Treated Sapphire Crystal: Virtually scratch-resistant crystal with a 99% super anti-reflective coating on both sides for perfect visibility. The case back is also made of sapphire.

Architectural Skeleton Design: Two-level dial that creates a sense of depth and allows you to admire the movement in operation.

Luxury Finishes (Sallaz Polishing): The case combines fine brushing with Sallaz mirror polishing, a traditional technique that denotes superior quality finishes.

Premium Construction: Case and bracelet made of high-quality stainless steel (SUS316L) for maximum corrosion resistance.

High Water Resistance: Screw-down crown and water resistance to 10 bar (100 metres), ideal for worry-free everyday use.

Power Reserve Indicator: A useful complication on the dial that shows the remaining power of the watch.

Full Functionality: Equipped with a second hand stop for precise time setting and manual winding capability.

The new Avant-garde Skeleton combines refined aesthetics and high performance, equipped with Orient Star's first automatic movement with a silicon escape wheel offering a 60-hour power reserve.

The complex design of the two-layer dial has been skilfully calculated so that the boundary between the movement is imperceptible. The upper plate with indices has a different colour and finish to the lower plate, which protects the upper plate from shocks and deformation. The second hands are arranged so that they protrude from the upper plate, giving a sense of depth and dimension to the distinctive skeletal structure. The SAR-coated sapphire crystal reduces light reflection by 99% and ensures that every facet of the design can be seen clearly.

The high-quality stainless steel (SUS316L) case and bezel with hexagonal screws have a delicate brushed finish that creates a strong sense of unity with the dial and movement, while the mirror finish achieved with Sallaz polishing adds a special touch to the watch. This model emphasises the solid metallic feel of the watch with a metal strap made from the same material as the case.

Case size (3H-9H): 42.3 mm

Stainless steel case

Water resistance 10 bar (100 m)

Sapphire crystal

Sapphire crystals protect the top of the watch. Sapphire crystals are the most scratch-resistant glass material available, as they are three times harder than mineral glass.

Transparent case back

A transparent panel on the back of the case allows you to see the elegant and modern design of the movement.

Water resistance

Water resistance up to 100 metres (10 bar).

Super anti-reflective crystal coating

Take visibility to a new level. Both surfaces of the sapphire crystal feature an anti-reflective coating that reduces light reflection by 99%. The observer will wonder if the crystal really exists.

60-hour power reserve indicator

60-hour power reserve indicator on the dial, designed to show the amount of stored energy remaining.
