Orient Star Contemporary Open Heart Green Dial Sapphire Glass Automatic Watch RE-AT0002E

Items Description

The Orient Star Contemporary Open Heart Green Dial Sapphire Glass Automatic Watch RE-AT0002E is a mechanical dress watch designed for enthusiasts who value traditional watchmaking with a contemporary aesthetic. This 39mm timepiece combines a rich green dial with an open-heart aperture and a power reserve indicator, offering a practical yet visually engaging experience for daily wear. The model belongs to Orient Star's Contemporary collection, which pairs in-house automatic movements with refined finishing at an accessible price point.

 

The watch is powered by an automatic movement that supports both hand-winding and hacking functions, delivering over 50 hours of power reserve when fully wound. Its stainless steel case is paired with a sapphire crystal featuring anti-reflective coating, ensuring clarity in various lighting conditions. The green dial serves as the visual anchor of this reference, distinguishing it from other Contemporary models through its depth of colour and the dynamic interplay between the open-heart cutout and the sweeping balance wheel beneath.

 

Key Advantages of the Orient Star Contemporary Open Heart Green Dial Sapphire Glass Automatic Watch RE-AT0002E

 

1. Green Dial with Open-Heart Complication

The dial of the RE-AT0002E is the defining characteristic of this reference, offering a distinctive look that changes with ambient light. Its green tone ranges from deep forest to brighter emerald depending on the angle, while the open-heart aperture at the 9 o'clock position reveals the balance wheel in motion.

 

• Open-Heart Display: A circular cutout exposes the escapement, providing a direct view of the mechanical movement at work.
• Power Reserve Indicator: A segmented arc at the 6 o'clock position tracks remaining winding energy, a practical addition for automatic watch owners.
• Applied Markers: Indexes and hands are finished with a silver-tone treatment that maintains legibility against the green backdrop.

 

2. In-House Automatic Movement with 50+ Hour Reserve

Orient Star equips this Contemporary model with a manufacture caliber that prioritises reliability and user convenience. The movement is visible through an exhibition case back, allowing owners to observe the decorated rotor and balance assembly during winding.

 

• Hand-Winding Support: The crown can be used to manually wind the mainspring, which speeds up initial setup when the watch has been sitting idle.
• Hacking Seconds: Pulling the crown to the time-setting position stops the seconds hand, enabling precise synchronization with a reference time source.
• Power Reserve: A full wind provides over 50 hours of operation, covering an overnight rest or a weekend away from the wrist.

 

3. Sapphire Crystal and Anti-Reflective Coating

The sapphire glass protecting this dial is treated to reduce glare, an important consideration for a watch with a coloured face and polished hands. Sapphire ranks high on the Mohs scale, making it resistant to the everyday scratches that can affect mineral or acrylic crystals.

 

• Durability: Sapphire crystal withstands contact with hard surfaces better than most alternative watch glasses.
• Optical Clarity: The anti-reflective coating minimises mirror-like reflections, allowing the green dial and open-heart detail to remain visible in bright conditions.
• Case Protection: A stainless steel case with a brushed and polished finish guards the movement from minor impacts and corrosion.

 

4. Contemporary Case Proportions for Everyday Wear

The RE-AT0002E measures 39mm in diameter, a size that suits a wide range of wrist sizes without feeling oversized or undersized. The case thickness and lug design contribute to a profile that slips comfortably under a shirt cuff, while the 20mm lug width offers standard strap compatibility.

 

• Case Diameter: 39mm presents a balanced presence on the wrist, fitting both formal and casual contexts.
• Strap Width: 20mm lugs allow easy swapping to leather, rubber, or NATO straps for style variation.
• Water Resistance: The case is rated for everyday use against splashes and brief immersion, though it is not intended for swimming or diving.

 

5. Japanese Craftsmanship from the Orient Star Line

Orient Star occupies a position above the mainstream Orient brand, focusing on mechanical watches with enhanced finishing and movement specifications. This model reflects that approach through its decorated rotor, sapphire glass, and the inclusion of complications typically reserved for higher-priced competitors.

 

• Brand Positioning: Orient Star markets this collection as a step up in finishing and mechanical sophistication within its catalogue.
• Movement Decoration: The visible rotor and bridges carry striping and perlage-style finishes that reward close inspection.
• Assembly Standards: Each example undergoes individual adjustment, reflected in the accuracy expectations for this class of automatic watch.

 

The Orient Star Contemporary Open Heart Green Dial Sapphire Glass Automatic Watch RE-AT0002E is best suited for collectors and first-time mechanical watch buyers who want an automatic movement with useful complications in a daily-wearable case. The combination of an open-heart display, power reserve indication, and hand-winding capability offers a level of engagement that quartz alternatives do not provide. For someone seeking a distinctive green-dialed dress watch with visible mechanics and dependable Japanese engineering, this model delivers a complete package without demanding the budget of Swiss counterparts.
