This vintage Omega Seamaster 600 Ref. 135.011 is a refined example of Omega’s 1960s craftsmanship, distinguished by its rare and highly desirable brown tropical dial. Originally dark, the dial has aged beautifully into warm chocolate tones, enhanced by a striking central red crosshair, adding balance and vintage character. Applied baton hour markers and slim hands preserve its clean, minimalist aesthetic. Housed in a classic stainless steel case (approx. 34–35 mm), the watch is powered by the reliable Omega manual-wind Caliber 601, known for its robustness and precision. The Seamaster 600 perfectly embodies understated elegance, combining timeless design with mechanical integrity. A true collector’s piece, this reference is especially sought after for its tropical dial and distinctive crosshair detail, making it a standout within the vintage Seamaster family.
