The reference 7928 was the second series of the Tudor's Submariner model and was launched in 1959. At the time, the cases were fitted with protective crown guards and were water-resistant to 200m/660ft. It remained in production until 1967. The dials always featured the Tudor rose symbol followed by "Oyster Prince" on the upper half, the lower half generally stating the depth rating 200m=660ft, Submariner, Rotor, Self-Winding on four lines.

The present reference 7928 stands out by its highly unusual dial, featuring a small, silvered line underneath the designation "Self-Winding", otherwise known to collectors as the "underline” and indicating the absence of radium on the indexes and hands.

The stunning dial presents itself clearly with its gilt printing and pointed crown guards on the case, also known as "Cornino". Furthermore, the case is preserved in very good, original overall condition.
