Notes: The Vintage Rolex Oyster Perpetual Date ref 6694 is a special watch because it is one of the few vintage Rolex watches that is not chronometer certified. This unique watch was introduced in the 1960s and offers the classic Rolex look. Measuring 34mm without the crown and 38mm with it, this watch is not too big or flashy. Rather, the subtle gold or stainless steel case is understated elegance at its best. The case also offers a signed screw down crown for optimal waterproof protection.

Mechanism: The Rolex 1225 is the date-version of caliber Rolex 1220, which represents a dramatic evolution of caliber Rolex 1210. Caliber Rolex 1220 shares the same mechanical platform of caliber Rolex 1210 with the exclusion of the Breguet spring. The balance wheel oscillating frequency increases from the original 2,5Hz (18000 vph) to 3Hz (21600 vph). Caliber Rolex 1225 is a Rolex 1220 caliber with the addition of a date module. The caliber's thickness moves therefore from the original 4,27mm of caliber Rolex 1220 to the 5,07mm of caliber Rolex 1225.

The 1225 is NOT chronometer certified.
