|title=Rolex 6234 Chronograph — Pre-Daytona, 1955–1961 | Rolexopedia

|description=The Rolex 6234 Oyster ~~Chronograph "Anti-Magnetique" — produced 1955 to 1961 in roughly 2~~,~~300 steel pieces~~ and ~~144 in two karat weights of yellow gold~~, ~~with~~ a ~~36mm screw-down Oyster case,~~ Valjoux 72 hand-wound movement~~, and a smooth bezel that pushes the tachymetre and telemeter scales onto the dial~~. ~~The chronograph that sits between~~ the 6034 ~~monobloc-case predecessor~~ and the 6238 ~~that ports the chronograph identity onto the Daytona-shared 36mm Oyster case~~.

|description=The Rolex 6234 is a 36mm Oyster chronograph generally dated 1955–1961, with pump pushers, a smooth bezel, printed tachymeter and telemeter scales, and a Valjoux 72-family hand-wound movement. It follows the 6034 and precedes the 6238.

~~Two references frame the position.~~ The 6034 ~~(1949 to 1955) is~~ the ~~antimagnetic predecessor, running the same Valjoux 72 under the same smooth bezel~~ in the ~~same triple-register layout~~, ~~on a different Oyster case construction~~. ~~Sheldrake records it as the first Rolex Oyster chronograph built on~~ a three-~~piece~~ case ~~rather than the monobloc~~ construction ~~of the 3525; the 6234 inherits that architecture~~ and ~~refines the~~ dial ~~layout~~. ~~The~~ 6238 ~~(1961/62 to 1967/68) is the successor~~; the ~~chronograph identity ported onto the 36mm Oyster case shared with the 6239, with the cal 72B carrying over from late-production 6234s into the first-series 6238 before~~ the ~~cal 722 redesign~~.

The 6034 precedes the 6234 in the Oyster chronograph sequence, and the 6238 follows it. The references share a three-register chronograph layout, but case construction, movement descriptions, and dial details vary between records. Some literature connects late 6234 Cal. 72B descriptions with early 6238 examples; the transition should be checked against the individual movement.

The 6234 predates the Cosmograph 6239. Sources generally place the Cosmograph designation with the 6239 in 1963 and the Daytona dial signature later; the 6234 itself has neither name.

~~Auction catalogues describe black-dial 6234 examples as infrequently offered.~~ The surviving auction sample is small, so the article records the individual lots rather than ~~ranking~~ the 6234 ~~against~~ every other pre-Daytona reference.

==Movement notes==

The movement is a Valjoux 72-family, hand-wound, column-wheel chronograph with three registers. Auction and reference literature use Cal. 72, 72A, and 72B descriptions; late 6234 and early 6238 transitions are a catalogue and movement-marking question.

The cited Valjoux 72 descriptions use an 18,000-vph frequency and manual winding. Jewel counts and ancillary features should be checked against the individual movement.

The movement runs at 18,000 vph (2.5 Hz), 17 jewels, manual wind, no hack, no quickset. The frequency increase to 21,600 vph waited for cal 727 in 1970, four references downstream. Tom Mulraney's [https://www.watchtime.com/brands/watches/tracking-the-rolex-daytona-a-53-year-history ''Tracking the Rolex Daytona''] essay for WatchTime (2016) records a period retail of about USD 200 for a 6234, a price point that places the chronograph below the smaller-volume gold Pateks and Vacherons of the mid-1950s and roughly in line with the rest of the Rolex sport-watch catalogue.

Many surviving 6234s are now on leather straps with Rolex pin buckles. Every Phillips lot recorded above (Start-Stop-Reset 2016, Geneva XV 2022, Geneva XVIII 2023) and the Sotheby's Olmsted 2025 example come on leather. The Sotheby's Daytona Capsule 2019 example (lot 11) is the one major-house lot in the captured record on its original rivet bracelet with folding clasp.

The Big Logo Gay Frères-stamped clasp is the period-correct fit on early 6234 production through 1958; the Small Logo Rolex-coronet clasp succeeds it from 1958 forward. ~~Neither carries a date code in the~~ modern single-letter ~~sense (that~~ system ~~does not start until~~ 1976~~), but the inside~~-~~clasp quarterly stamp on~~ Gay Frères clasps ~~from the late 1950s reads as <code><~~Roman quarter~~>.<~~two-digit year~~></code> (for example "~~II.58~~" for second quarter 1958)~~. The clasp dates the bracelet, not the watch head; see [[Reference:Bracelets]] for the full date-code key.

The Big Logo Gay Frères-stamped clasp is the period-correct fit on early 6234 production through 1958; the Small Logo Rolex-coronet clasp succeeds it from 1958 forward. The modern single-letter clasp code system begins in 1976. Late-1950s Gay Frères clasps may instead carry a quarterly Roman-quarter and two-digit-year stamp, such as II.58. The clasp dates the bracelet, not the watch head; see [[Reference:Bracelets]] for the full date-code key.
