Early 1940s Rolex Bubbleback ss popular semi-unique dial with a very rare sub-second. This model is equipped with a sub-second movement, Cal. 620, which is very rare in the semi-unique dials where center-second models are predominantly used. The unique design of the sub-second model and the ageing of the texture are wonderfully appealing, and the old two-piece case with a precious mid-crown is a product with a period look.
