Reference:3139: Difference between revisions

Line 95:

The right frame is commercial, not military-contract. Rolex sold the 3139 to wartime buyers through normal channels, but there is no sign of formal government issue. The military styling is real. The contract-watch reading is not.

Which commercial channels carried it is itself undocumented. Contemporary Canadian-market Oysters sit in the retailer archives of Birks and Eaton's; the 3139 does not turn up in those records the same way, which is consistent with a broadly targeted product rather than a retailer-specific private label.

Line 105:

The case carries the reference 3139 engraved between the lugs on the underside, and the standard Oyster caseback text on the interior. The back is a screw-down three-piece element consistent with Oyster architecture. The crown is a screw-down Oyster Patent crown, threaded to the case tube.

Two case sizes are documented under the same reference: a more common mid-size around 30x30mm and a larger 30x35mm variant. Both are legitimate. Buyers should measure the watch rather than assume one fixed size.

Two case sizes are documented under the same reference: a more common mid-size around 30x30mm and a larger 30x35mm variant. Both are legitimate. Buyers should measure the watch rather than assume one fixed size. Whether the two ran in parallel, in sequence, or for different markets is not documented in the surfaced record.

Known case numbers anchor the reference to specific production years. Antiquorum dates case 244828 to 1942, 244874 to about 1943, and 245141 to about 1945. Case 275869 appears in the dealer record without a firm date. The outlier is 382045, catalogued by Antiquorum as "1930s," which is implausible given the reference's 1938 production start; the serial sits in a mid-1940s range, and the catalog dating reads as a typographic or indexing error rather than a real attribution.
