During the 70s, Omega employed tuning fork movements in many of their watches, as was the fashion at the time. The ESA 9162 / ESA 9184 movements are often considered the Rolls Royce of this style of movement and were designed by Max Hetzel, the brains behind the Bulova Accutron 214, used in the Apollo space programme a decade earlier.

The Omega watches employing these tuning fork movements were usually referred to as the ‘Omega f300’ models reflecting the frequency of the tuning fork. FYI, the Accutron 214 functions at 350 hz.


Please note that due to the delicate nature of tuning-fork watches they will need a professional battery replacement every 9– 18 months.

We are happy to note the date of purchase and phone the customer after a 12-month timeframe has elapsed to facilitate a professionally executed battery replacement.

Please feel free to call us or drop us a line with any questions.

Please note that classic and antique watches cannot be considered water-resistant or water-proof by modern standards, even if stated on the piece itself. We do strive to renew seals and ensure the best protection from moisture that each watch will allow but we cannot guarrantee this work will survive prolonged exposure to liquids.
