Cased in an array of metals and fitted with a variety of dials, "Bubble Back" watches were in production for over 22 years, from the early Thirties to the mid Fifties. For many years, the "Bubble Back" wristwatch was Rolex’s best selling model. At the time of production, the model was officially named the "Oyster Perpetual". The nickname "Bubble Back" is derived from the convex shape of the case back used to house the new automatic winding system, which replaced the manual mechanism.

The present watch is a highly attractive stainless steel version. It is distinguished by its luminous "bow tie" dial - so called for its geometric design that resembles its namesake. The luminous material has aged evenly with the hands, and provides enormous charm. As an even nicer touch, the dial displays a Beyer signature, indicating the timepiece was sold at the storied retailer. Many existing "Bubble Back" wristwatches have been altered over time, yet this example is preserved in excellent and original overall condition. The watch even retains its original vintage Rolex buckle.
