Case & Dial
The 42mm case is crafted in stainless steel with a combination of polished and brushed surfaces for a refined look. The dial features applied hour markers with luminous fill, ensuring clear visibility in all lighting conditions. Chronograph sub-dials are cleanly integrated into the dial layout, and a date window provides everyday utility.
Movement
Powered by a Co-Axial chronograph caliber featuring a column-wheel mechanism for precise start-stop-reset action. The Co-Axial escapement reduces friction between components, resulting in improved long-term timing accuracy and longer service intervals compared to traditional lever escapements. A sapphire display caseback reveals the movement finishing, including decorated rotor and bridges.
Design Details
Attention to detail is evident throughout the construction. The stainless steel construction ensures durability for daily wear while maintaining its appearance over time. The crown is signed with the Omega logo, and the clasp mechanism provides secure and comfortable fit on the wrist.
