Case no. 2845270
This 1675 was made in 1960s with its original Oyster bracelet. The watch is in its unpolished original condition and the bracelet is in 75% condition and the dial is good.
The bezel insert colors have faded to a beautiful hue.
For Vintage Rolexes, the original condition is much desire and command a high premium over a heavily polished piece of same model.
In 1959, Rolex introduced the GMT-Master 1675. This models comes very close to the more modern variations which have been in production till recently (ref.16710). The 1675 had a case measuring 40mm in diameter, crown-guards and an aluminium inlay. The movement also changed a bit and became Rolex caliber 1575.
Occasionally, a GMT-Master 1675 with a caliber 1570 inside, the base caliber for this self-winding movement is 1570 and was left engraved on the bridge of caliber 1575.
There also have been production numbers of the 1675 GMT-Master with caliber 1565 but it is unclear when these were used and in which particular models.
