[BIG LOGO]

The so-called "BIG LOGO" where the ROLEX logo on the dial is noticeably larger.

It is a rare detail only seen in the early production of Oyster Perpetual Ref. 1500 and Ref. 1501, due to its very short manufacturing period.

The "BIG LOGO" is well-matched with wedge-shaped indexes and Alpha hands, evoking the charm of the 1950s, and it even features a blued steel hand, which is a welcome bonus.
