Orient Star Open Heart Limited Edition Turquoise Blue Gradation Watch RE-AT0017L

Items Description

The Orient Star Open Heart Limited Edition Turquoise Blue Gradation Watch RE-AT0017L is a mechanical timepiece designed for collectors and enthusiasts who appreciate Japanese watchmaking artistry. This limited edition model, restricted to just 850 pieces worldwide, showcases a striking turquoise blue gradation dial that sits at the heart of the Contemporary Semi-Skeleton collection. The open heart aperture at 9 o'clock reveals the inner workings of the automatic movement, offering a window into the precision engineering beneath the surface.

 

Crafted from stainless steel with a case diameter of 41mm, the RE-AT0017L balances a robust presence with refined elegance. The gradient dial transitions from a deep turquoise at the edges to a lighter blue towards the centre, a finish achieved through Orient Star's specialised dial-making techniques. The sapphire crystal protects the dial while allowing an unobstructed view of the exhibition case back, where the 22-jewel automatic calibre F6B22 can be observed in motion. This watch functions as both a reliable daily timekeeper and a statement piece that celebrates the brand's heritage of mechanical craftsmanship.

 

Key Advantages of the Orient Star Open Heart Limited Edition Turquoise Blue Gradation Watch RE-AT0017L

 

1. Distinctive Limited Edition Status

The RE-AT0017L belongs to a strictly numbered production run of 850 pieces, making it a rare find for collectors seeking something beyond mass-produced timepieces. Each unit carries its own serial number, confirming its place within this exclusive series. The turquoise blue gradation dial, paired with the open heart complication, differentiates this model from standard Orient Star offerings and gives owners a conversation-worthy timepiece with genuine scarcity value.

 

• Production Cap: Limited to 850 examples worldwide, adding collectable appeal.
• Numbered Series: Each watch is individually numbered for authenticity.
• Distinct Dial: Turquoise gradation finish sets it apart from regular catalogue models.

 

2. Open Heart Mechanical Calibre F6B22

At the core of the RE-AT0017L sits the in-house automatic movement F6B22, visible through the open heart aperture on the dial. This 22-jewel calibre operates at a frequency of 21,600 vibrations per hour and delivers a power reserve of approximately 50 hours when fully wound. The movement also offers hand-winding capability and a hacking seconds function, allowing for precise time setting. The semi-skeleton design provides a glimpse of the balance wheel in action, offering a continuous mechanical spectacle for the wearer.

 

• Power Reserve: Approximately 50 hours of autonomy once fully wound.
• Jewels: 21,600 vph frequency with 22-jewel construction for smooth operation.
• Visibility: Open heart cut-out at 9 o'clock reveals the oscillating balance wheel.

 

3. Turquoise Blue Gradation Dial and Design Execution

The dial of this limited edition is its defining visual feature, employing a gradient technique that shifts from a rich turquoise tone at the perimeter to a paler blue near the centre. This depth of colour is achieved through multiple layers of lacquer applied by hand, a process that creates subtle variations between individual pieces. Applied index markers and dauphine-style hands in a silver-tone finish provide contrast against the coloured surface, while the date window sits discreetly at 3 o'clock. The overall effect is a dial that changes character depending on the lighting, from deep ocean hues under dim conditions to brighter, more vivid blues in daylight.

 

• Dial Finish: Multi-layer lacquer creates a seamless turquoise blue transition.
• Hands and Markers: Silver-tone applied indices paired with dauphine hands for legibility.
• Date Function: Practical date window positioned at 3 o'clock.

 

4. Stainless Steel Construction with Sapphire Crystal

Built to withstand daily wear, the RE-AT0017L uses a stainless steel case measuring 41mm in diameter and 13mm in thickness. The caseback is secured with screws and features an exhibition window, also protected by sapphire crystal, allowing a clear view of the decorated movement. The main dial side is guarded by a sapphire crystal with anti-reflective coating on the inner surface, reducing glare and improving readability. With a water resistance rating of 50 metres, this watch suits everyday activities such as hand washing and light rain but is not intended for swimming or diving.

 

• Case Size: 41mm diameter and 13mm thickness offer a versatile fit.
• Crystal Protection: Sapphire glass with inner anti-reflective coating on both front and caseback.
• Water Resistance: 5 ATM rating suitable for daily use, not water sports.

 

The Orient Star Open Heart Limited Edition Turquoise Blue Gradation Watch RE-AT0017L is best suited for mechanical watch enthusiasts and collectors who value limited production runs, hand-finished dials, and visible movement architecture. For those seeking a daily-wear automatic with a distinctive aesthetic and the reassurance of a numbered series, this Orient Star offers a combination of craftsmanship and rarity that standard production models cannot match.
