Essay

The Calibre 320, a column wheel chronograph movement developed by Lemania, stands as one of the most technically robust and mechanically refined chronographs of the 20th century. Often overshadowed by its more famous counterpart, the Calibre 321, the 320 was produced during a period when mechanical precision and build quality were paramount. Extensively utilized by Omega throughout the 1960s, it remains a benchmark for reliability and movement architecture, featuring a compact layout and durable chronograph mechanism that exemplify high horological standards of its era.
