Rolex Precision 3140

A checked version of this page, approved on 11 October 2026, was based on this revision.

The 3140 is a manual-wind Rolex Precision catalogued as a long rectangular gold watch and, in one later listing, a small diamond-set bracelet watch. Auction catalogues date individual examples from the 1930s to the 1950s; the reference’s earliest and latest production dates remain unknown. Each specification below belongs to an individual watch.

Where it sits in the line

Colin A. White, Christie’s and Monaco Legend classify rectangular examples as Precision. Antiquorum called its 1996 example a Prince. Published watches vary in case and movement; the sections below keep the details tied to each lot.

Antiquorum’s 1996 catalogue calls one rectangular 3140 a Prince, while Christie’s and Monaco Legend call their examples Precision. One catalogue label does not settle the family name for every watch; the 3140 article keeps each account tied to its individual lot.

Production outline

Christie’s dates case 41,362 to 1937 and case 56,497 to the 1940s. It dates case 41,323 to the 1930s and reports a Glasgow import mark for 1937. Antiquorum dates another rectangular example to circa 1950. These catalogue dates describe individual watches; the earliest and latest production dates remain unknown.

Antiquorum’s 2025 listing dates a small white-gold diamond-set watch to circa the 1950s. Its size, integrated bracelet and Cal. 1401 differ from the long rectangular watches. The catalogue identifies it as a 3140, but does not explain the design or establish when it appeared.

Movement notes

Christie’s describes case 41,362, dated 1937, with a 17-jewel Cal. 360 that it calls rectangular-shaped. Monaco Legend’s 1937 example, case 41,465, is also catalogued with Cal. 360, but its description does not give a jewel count. A 1999 Antiquorum lot instead describes an 18-jewel, 8-line Ultra Prima movement in a 1930s 3140. Christie’s circa-1950 example has a 17-jewel tonneau-shaped movement adjusted to seven positions. Its 1940s lot describes a nickel-plated movement adjusted to seven positions, without naming a caliber.

Sources disagree on whether Cal. 360 is rectangular or tonneau-shaped. The 3140 catalogues add two Cal. 360 attributions and a separate Ultra Prima description. They leave the movement sequence and the originality of individual movements unresolved. The movement index records the conflicting Cal. 360 descriptions.

Dial map

The catalogued rectangular examples use subsidiary seconds. Christie’s case 41,362 has a silvered matte dial with applied Arabic numerals; its 1930s case 41,323 has a two-tone silvered dial with Arabic numerals and blued-steel hands. Antiquorum’s 1999 lot describes a two-tone silver dial with painted Arabic numerals and blued lozenge hands. Its circa-1950 lot has a silvered dial with gilt baton markers and an Arabic 12.

The 1940s pink-gold listing describes a two-tone gilt dial with Arabic quarter-hour marks, baton minute divisions and luminous blued-steel hands. Antiquorum describes the dial on its 2025 white-gold example as reprinted, so that watch belongs in a record of later dial states rather than the factory dial map.

Case, bezel, crystal, and crown

The best-documented early form is rectangular with hooded or concealed lugs and a snap-on back. Christie’s describes 9-carat yellow gold in cases 41,323 and 41,362. The 1937 Monaco Legend example is yellow gold; the 1940s Christie’s lot is pink gold. A 1999 Antiquorum example is described as a two-body 9-carat case with cylindrical hooded lugs. Christie’s circa-1950 lot describes pierced concealed lugs. Those are observed catalogue descriptions, not a proven sequence of case revisions.

Catalogue measurements use different conventions: examples include 22 × 38 mm, 38 × 21 mm and 22 × 30 mm. They are not directly comparable. The 2025 Antiquorum watch is listed at 15 × 18 mm, with a diamond-set bezel and integrated bracelet. The cited lot records do not give a reference-wide crystal or crown specification.

Bracelets, clasps, and packaging

Monaco Legend records a yellow-gold bracelet on case 41,465, with a total length of 222 mm; its photographs show broad rectangular links. Christie's circa-1950 example came with an associated 9-carat gold bracelet. Antiquorum’s white-gold example has an integrated textured bracelet. These records document what accompanied each lot, not original delivery or universal 3140 fitment. One Bonhams 2013 catalogue record reports a fitted Tudor box with case 41,310; the box is an accessory to that lot, not reference-specific packaging.

Special branches

Catalogue records show two distinct forms under 3140: long rectangular gold watches with subsidiary seconds, and a small white-gold, diamond-set bracelet watch. The surviving documentation leaves unclear whether Rolex treated them as one design family or reused the number across separate variants. Measurements, materials and movements remain specific to each example.

Antiquorum’s 1996 lot 445 attributes a 3140 to Al Capone. Sotheby’s 2024 catalogue links case 41,470 to that lot but says the ownership claim could not be verified. Antiquorum gives no case number for its 1996 watch, so readers cannot check the identification against both records.
