Brought to the world in 1939, the ref. 3525 was Rolex’s very first chronograph wristwatch to be housed in an Oyster case and featured a water resistant screw down case back as well as a screw down winding crown. The ref. 3525 was offered in yellow gold, pink gold and stainless steel, such as the present execution. The ref. 3525 has delightfully been nicknamed the “Monoblocco” by Italian collectors, in reference to the fact that the entire case including the lugs and bezel were manufactured in “one block” with the exception of the screw-down caseback.

Likely the most awe-inspiring feature, the black glossy dial of the present watch impresses its beholders with a stunning tone which contrasts beautifully with the gilded indexes and scales. The brushed finishing of the stainless steel case, with its flat, wide bezel, matches well with the overall design of the dial. The multi-scale dial with gilded print remains stunning and sharp. The present wristwatch is undoubtedly a fascinating and highly collectible piece of Rolex history.
