A very rare Rolex Oyster Bubbleback Ref. 2764 from the late 1940s, featuring a semi-unique dial and a sub-seconds layout.
While center seconds are overwhelmingly more common in both unique and semi-unique dial configurations, this piece stands out for being equipped with the rare Cal. 620 sub-seconds movement.
The distinctive design and well-aged patina, unique to semi-unique dial and sub-seconds models, give this piece a remarkable vintage character.
It is housed in a robust Oyster case with an integrated bezel and middle case, and features the uncommon Cal. 620 small seconds movement—an unusual choice for this period.
