The "bubble back" was during a period of over 20 years one of the firm's best-sellers, made in a nearly unlimited number of variations in terms of case shape, case material and dial designs.

The present example reunites every conceivable element a "bubble back" collector can possibly aspire to: the fancy steel and pink gold case, a rose-colored California dial highlighted with luminous numerals and the stainless steel and pink gold Rolex Oyster bracelet.
