【Excellent Condition】Omega Seamaster Cosmic, Accuracy Adjusted, Hand-Winding 136017 SP 【Overview】 The "Seamaster Cosmic" appeared in the late 1960s. This watch is a testament to Omega's sense of style at the time, blending futuristic design with classical ornamentation. This model features an elegant combination of a gold-plated case and a silver dial, making it a classic dress watch suitable for both business and casual occasions. The movement is the highly reliable Cal. 613 (hand-winding). The second hand moves smoothly, and the accuracy has been adjusted, with a daily rate of +6 seconds, confirming very stable operation.
