This Omega Seamaster Electronic f300 Hz Chronometer, reference 198.001, is a beautifully preserved example of Omega’s most innovative era of the 1970s. Powered by the Omega caliber 1250 tuning-fork movement, the watch delivers the signature ultra-smooth sweep of the seconds hand that defines f300 technology. The silver sunburst dial remains crisp and balanced, complemented by original hands and the distinctive red seconds hand. Housed in a sharp, stainless steel case with a well-defined Seamaster hippocampus caseback, this watch retains its original Omega bracelet and signed folding clasp. An honest, fully original Seamaster that blends vintage elegance with cutting-edge horological history.
