The Omega Men’s 123.10.35.20.01.001 Constellation Chronometer Black Dial Watch stands as a testament to Swiss watchmaking excellence, blending timeless design with mechanical precision.

Whether worn daily or reserved for special moments, this timepiece delivers dependable performance with understated elegance.

Key Features

• Co-Axial Calibre 2500 Movement – This in-house developed automatic movement represents a significant evolution in horological technology. By introducing a co-axial escapement, Omega reduces internal friction and wear, which enhances long-term reliability and decreases the frequency of required servicing. The movement operates at 28,800 vibrations per hour and offers a power reserve sufficient for everyday use without interruption.
• Black Dial Design – The deep black dial provides a striking contrast against polished hour markers and hands, ensuring excellent legibility in both bright and low-light environments. Its minimalist layout emphasizes clarity and sophistication, staying true to the Constellation line’s reputation for clean, balanced aesthetics.
• Stainless Steel Construction – Crafted entirely from high-grade stainless steel, the case and matching bracelet offer durability and resistance to corrosion, scratches, and daily wear. The polished finish enhances its refined appearance, making it suitable for professional and formal settings.
• Chronometer Certification – Officially certified as a chronometer, this watch has undergone stringent testing for precision and stability. This certification confirms that it meets or exceeds the standards set for mechanical timepieces, delivering reliable accuracy over time.
• Automatic Winding System – The watch winds itself through the natural movement of the wearer’s arm, storing energy in the mainspring to power the movement. This eliminates the need for battery replacements and supports sustainable, long-term use.
