With acrylic crystal and bi-directional elapsed time bezel. Guaranteed genuine, just fully serviced by our Rolex trained watchmaker,  and offered with our 1 year warranty of accurate time keeping and operation. Serif dial refers to the 1970's era dials with ornamental (serif) details to the 3/6/9 luminous markers, and the hour indexes along the perimeter of the dial. The luminous dots are also larger than the earlier Submariner models, but are technically not considered "Maxi" dials.  These serif dial models, especially when turned a warm ivory color like the current example, add to the popularity and desirability of this classic no date Submariner model.
