ROLEX CHRONOGRAPH PRE-DAYTONA REF. 6234 UNPOLISHED
The Rolex Chronograph reference 6234 is undoubtedly one of the most sought-after pre-Daytona models among collectors. It was produced for only about 6 years, from 1956 to 1961, when it was replaced by the reference 6238, the last pre-Daytona model before the introduction of the reference 6239. The reference 6234 is an exceptionally rare pre-Daytona model, as several Rolex vintage experts agree that the total production is estimated at only 2300 pieces in steel and less than 150 in 14k or 18k yellow gold. The main features of this rare Rolex chronograph are the 36mm Oyster case with screw-down caseback, the pump pushers and the Valjoux 72 hand-wound movement. Also important is the fact that the tachymeter scale is printed on the dial and not engraved on the bezel, as is the case with all Daytona references from 6239 onwards. The 6234 was produced with a variety of dial types, differing by both final sales market and production year.
Very few examples of reference 6234 were made, and even fewer have survived in exceptional condition to this day. These watches often have poorly polished cases and damaged dials. This is not the case with the present specimen. It is surprisingly very well preserved and in excellent overall condition. The case is most likely unpolished and retains the original factory proportions with strong and sharp lugs. The dial shows no major signs of aging, the caliber is in perfect condition, and the caseback screws down perfectly. Note that the main feature of this specimen is the correspondence between the dial with telemetric and tachymetric scales in Miles (typical of pre-Daytonas sold in the United States) and the movement marked ROW. The latter is present in all watches sold in the United States during the production period of this 6234.
All components are correct and original to the production period, including the dial, the Rolex signed Valjoux 72 caliber, and the 6234 signed caseback.
Serial Number 534,XXX, Year 1960.
