3 ACCUTRON 218 CLEAR EXHIBITION CASE BACK W/ RINGs

The OD of the caseback must be 30.5mm for the clear crystal case back to fit. If your Accutron 218 has a bezel larger than 34mm, the retaining ring is too small. Have you ever dismissed buying a Bulova Accutron 218 because the case back was engraved?.

Vintage Bulova Accutron 2181 – restored and serviced.

It was trusted enough by NASA to fly aboard Gemini and Apollo missions and served as the panel clock on several spacecraft. The Accutron 218 runs on a battery-driven tuning fork oscillating at 360 Hz (720 beats per second), with an index wheel converting that vibration into smooth rotary motion.
