You thought you knew it all about the “Big Red”? Here is a rare transitional dial between the “Sigma” period and the “Big Red” period. In the old days Rolex did not want to throw away dials that were already made for the previous version of their watches. Sigma dials were promoting the use of gold in the watches.

Magnificent collector's watch, in excellent condition. Each component is contemporary and original of the era.
