Important Notice regarding importation into the United States of Rolex watches

The reference 5513 became an official Military issue model after the British Royal Navy commissioned a series of Submariners with specific adaptations. The dial was marked with an encircled 'T' to indicate the use of the luminous material tritium. The outside of the case backs were marked with the military broad arrow sign, Ministry of Defence issue numbers and unit number. The watches were also fitted with the hacking feature which was only introduced on the chronometer models at a later date and allowed the easy synchronisation of time, an especially useful function for troops on operations.
