This Omega Electronic f300Hz from 1973 pairs late‑1960s/early‑1970s styling with a distinctive jumbo case and tuning‑fork regulation. The design emphasises clarity and presence on the wrist, with proportions that speak to the era’s taste for bold, modern cases. At its heart sits the Cal. 1250 (ESA 9162) tuning‑fork movement, an alternative electro‑mechanical approach valued for its steady beat and technical interest. For a contemporary collector, it represents a clear snapshot of a transitional moment in watchmaking and a mechanically intriguing complement to traditional mechanical and quartz pieces.
