Bulova Accutron Calibrator 65B148 Watch

Bulova Accutron presents the first ever automatic watch that lets the wearer individually control its accuracy thanks to the External Fine Adjustment System (EFAS). No need for a professional; the wearer operates the system by inserting a key at the 9 o'clock position to achieve precision of 99.99% on average. The case in stainless steel with rose-gold PVD coating accents integrates an anti-reflective sapphire crystal, while a screw-down transparent back gives a clear view of the automatic mechanism with its 26 jewels. The EFAS indication with retrograde hand is positioned opposite the date window.. Water-resistant to 50 metres, the Calibrator is mounted on a black leather strap incorporating a folding clasp with double pushers.
