The Rolex Prince, or "Doctor’s Watch," was originally released to the market in 1928. The model features an oversized subsidiary seconds dial below the hours and minutes section of the dial, enabling a doctor to time the respiration and pulse rate of their patients. The flared and elongated case sides of certain Prince references led to another nickname, “Brancard,” for the French word for stretcher. Marketing of the era called it “the watch for men of distinction,” and touted its observatory-grade precision, as well as its curved, ergonomic case.

On the inside caseback, a new dimension of this watch’s story is revealed. The British sponsor’s mark “R.W.C. Ltd.” can be seen stamped within, as well as the Glasgow Assay Office hallmark and the date letter “k” for 1933. Thus, one can surmise that the present watch was imported to London and then onward to Scotland, where it was likely sold.
