Omega Seamaster Chronometer

Omega Seamaster Chronometer armbandsur med elektroniskt urverk. Klockan har datumvisning och tillhörande armband.

This is a vintage Omega Seamaster Electronic f300Hz, a historically significant timepiece from the early 1970s. It represents a unique era in watchmaking when mechanical engineering met early electronics.

The "f300Hz" on the dial indicates that this is a Tuning Fork watch. Unlike a standard mechanical watch (which ticks) or a modern quartz watch (which usually pulses once per second), this watch uses a vibrating tuning fork powered by a battery.
?The Hum: If you hold this watch to your ear, you will hear a distinct humming sound rather than a tick.
?The Sweep: The second hand on these models moves in a perfectly smooth, continuous motion.

The red trapezoidal logo at 12 o’clock is a signature mark for Omega’s electronic and early quartz tuning fork models.
?Hands and Markers: It features baton-style hour markers and hands with aged luminous material (which has turned a creamy yellow/tan color).

This model (likely reference 198.001 or similar) features a "C-shape" or integrated-style stainless steel case, which was very popular in the 1970s.
?Integrated Bracelet: The watch is fitted on a stainless steel link bracelet that appears to be original to the style of the period, tapering slightly toward the clasp.
