Rolex Oyster Perpetual Datejust reference 6305

Partially verified

This Rolex Oyster Perpetual Datejust wristwatch, identified by reference 6305, dates to 1950. The watch features a 36mm case constructed from a combination of stainless steel and 18ct yellow gold. The off-white dial displays yellow gold baton hour markers, an applied Rolex crown logo, and a date aperture located at the 3 o'clock position. The exterior edge of the dial includes a minute-counting track. The timepiece is powered by the A.296 caliber movement, as reported by the source. While the source notes the dial text includes 'Officially Certified Chronometer', this status remains an unverified claim. The catalogue entry lists the movement as manual in some fields and self-winding in others, resulting in uncertainty regarding the winding mechanism. The watch is presented in a two-tone configuration consistent with the era's Rolex Oyster designs.

Object description

Case and Dial

The watch is housed in a 36mm case combining stainless steel and 18ct yellow gold, featuring a fluted bezel. The case construction follows the Oyster design, a hallmark of the Datejust series. A screw-down winding crown sits at the 3 o'clock position.

The dial is finished in an off-white tone, accented with 18ct yellow gold baton indices. The Rolex crown logo is applied to the upper section of the dial, while a date aperture is positioned at 3 o'clock. A peripheral minute track is printed on the outer edge of the dial surface.

Movement and Configuration

According to the source documentation, the timepiece is equipped with the A.296 caliber movement. The source contains conflicting information regarding the winding mechanism, noting a manual entry in the technical table while the model is identified as an Oyster Perpetual.

The text on the dial specifies 'Officially Certified Chronometer', though the source notes this is a claim that requires formal verification through testing or archival certificates. The specific functional state of the movement is not independently confirmed by the current record.

The object is catalogued under the reference number 6305 with a Somlo identifier of 2985. The manufacture date is cited as 1950. The current listing indicates the watch is accompanied by a leather strap, though the overall scope of original accessories remains unspecified.

This record relies on the provided auction description, which serves as the primary reference for the object's stated attributes. No external evidence regarding the history of the piece or its service record is included in the current documentation.
