Rolex

Submariner Date

Ref.126613LB

This model became a hot topic as the world's first diver's watch equipped with a rotating bezel for measuring dive time. It was developed for true professional divers who work in harsh environments.

Nicknamed the "Blue Sub," this is one of the most popular and well-known two-tone models. The case size has been increased from 40mm to 41mm, a crown mark has been added to the dial at 6 o'clock, and the movement has been upgraded from Cal. 3135 to Cal. 3235 (with a power reserve of 70 hours, up from 48 hours).

This model is a combination of stainless steel and 18K yellow gold, and the change from the gold lettering of the previous model to white lettering gives it a refreshing impression.
