Ring watches were produced by Rolex in an attempt to expand its line of offerings. Pendant watches, pin watches, and travel clocks were all part of a small line of accessories and were made in very limited quantities. There has only ever been 1 other exact same ring watch offered at auction before, bearing a case number only seven numbers apart, a testament to the small production numbers of these.
