1972 ULTRA CHRON CUSHION CASE AUTOMATIC DATE CAL 6651 EXCELL À MARTIGUES

1972 Ultra Chron Cushion Case Automatic Date Cal 6651 Excellent Condition History In 1967, Longines launches the Ultra-Chron, with a self-winding 11″ line caliber aiming to offer an alternative to the electronics and quartz used by the competition. The regulating organ of the L430 movement is a guarantee of accuracy, with the characteristics of a competition piece as it vibrates at a frequency of 36,000 vibrations per hour. The Caliber 6651 released in 1972 is the same quality movement with minor modifications done to lower its rate down to 28600 bph, adjusted to 4 positions to increase its accuracy.  Longines made that move to remedy the issue they faced with high frequency movements, which required a lot more attention and maintenance. It resulted in offering one of the best quality movement Longines has ever produced.  The watch  The condition of the watch is excellent, the case, the dial, hands and indexes and the movement are all original and in mint condition.  The bezel still has its original Sun-ray brushed finish, as the case has never been re-polished.  The watch functions work perfectly, date change, hand setting,  push pull of the crown, winding action….  My wrist is 7,1 Inches or 18cm wide (medium size).
