Reference 6234 was first introduced in 1955, and is considered to be one of the rarest gems amongst the Rolex Oyster chronograph family. Both references 6034 and 6234 are highly desirable in the collector community, considered precursors to the Cosmograph Daytona whose case shape they influenced. The majority were cased in stainless steel cases and an extremely rare number produced in yellow gold. Cased in 14k yellow gold, the present model was made for the American market as confirmed by the ROW inscription on the balance bridge. The present lot is also a transitional model fitted with a coveted “underline” dial, referring to the underline beneath the ‘Anti-Magnetic’ designation at 6 o’clock. The symbol was used by Rolex in the early 1960s to signify the use of tritium for the luminous dial and hands. Well preserved in overall wonderful condition, this reference 6234 is further enhanced by an utterly sumptuous, period correct woven yellow gold herringbone bracelet made by Gay Frères. Prominently featured in Pucci Papaleo’s “I Cronografi Rolex - La Legenda”, it’s a rare and superb example noted for its stunning beauty.
