Omega Seamaster 600 “Technical Dial” – Cal. 601 – Ref. 135.012 The Omega Seamaster 600 Ref. 135.012 is a classic hand-wound Seamaster from the 1960s, powered by Omega’s dependable Calibre 601. Despite the “600” designation, the name refers to the model line rather than a 600-meter depth rating. The reference is appreciated for its slim profile, elegant elongated lugs and straightforward manual-winding construction, representing the functional side of mid-century Omega design. What makes this example especially distinctive is its Technical Dial configuration. The dark dial uses an unusually detailed double minute/seconds track with dense white markings, warm gold-tone indexes and contrasting red crosshair lines. The combination creates an almost instrument-like appearance while retaining the elegant proportions of a traditional Seamaster 600. Important Photo & Color Note: High-resolution images may exaggerate minor imperfections not visible to the naked eye. Photographs were taken using professional camera equipment and controlled lighting; therefore, the dial, case, and strap may appear slightly darker, brighter, or different in tone depending on ambient lighting, direct sunlight, viewing angle, and screen settings.
