What makes the reference 3668 so desirable is that it is one of the first Rolex chronographs that was fitted with an Oyster-case and a screw down crown. It was released rather quickly in succession of the reference 3481, which was in 1939 the very first Rolex chronograph to be fitted with these signature Rolex features. While the reference 3668 is larger than the reference 3481, it is still modest by modern standards with a diameter of only 35mm.

The watch was equipped with a Cal. 23 VZ nickel-finished lever movement made by Valjoux, which was fitted with a column wheel and supported subsidiary dials for a constant seconds as well as a 30-minute register for the chronograph. The blued hands of the watch stand out against the rose/salmon color of the dial, which has gained a beautiful patina over the years. Especially in combination with the gold crown and bezel, it looks very stunning.

The dial of the watch offers a lot of information, as Rolex incorporated a Tachymeter and Telemeter scale, yet they all remain very legible. This is quite an accomplishment given the relatively small diameter of the watch. The bezel also helps in that regard, clearly marking the hours, yet is distinctly different from the Rolex bezels we know today. It most certainly adds to the charm of the reference 3668, and why this chronograph has become increasingly more popular among collectors in recent years.
