Notes: This model is also known as the Bombe or Bombay due to the curvature of the band lugs. Reference 6290 is also a Bombay, but used 18K rose gold instead of 14K.
Mechanism:
The 630 was Rolex's second automatic mechanism. The 640 is a variation of the 630 featuring sweep-seconds, moonphase and calendar. It is one of the three size A.260 mechanisms.
Family Notes: In 1926, Hans Wilsdorf introduced the Oyster watch which used a waterproof case, hence the name. He added "Perpetual" to the name when in 1933 he introduced a reliable automatic self-winding watch. Hence the name means "Waterproof, Self-Winding" in Rolex-speak and generally means the watch is water resistant to a depth of 100 meters.
