Dealer and auction listings also identify ref. 5045 examples around 1949–50; the Loupe This lot includes a photograph of the inner caseback stamp. The 5002 records describe 23–26 mm steel, two-tone, and gold cases; 5006 records give 29–30 mm steel and gold examples. For 5013, Doyle and Linckersdorff list solid-gold watches; Curious Curio, Cool Auction, and GMTBroker describe steel cases with gold bezels. The examined listings show several dial layouts, but do not establish their order or factory originality. Cool Auction assigns Cal. 630 / 630NA to its individual watch. A Rolex Forums chart gives 9.75 lignes, a size notation rather than a caliber. One marketplace listing describes a centre-seconds chapter-ring 5013, but its photograph shows no reference stamp or caseback, so that attribution is unverified. These dates and configurations belong to individual records, not production endpoints.

For 5013, Doyle and Linckersdorff list solid-gold watches; Curious Curio, Cool Auction, and GMTBroker describe steel cases with gold bezels. The examined listings show several dial layouts, but do not establish their order or factory originality. Cool Auction assigns Cal. 630 / 630NA to its individual watch. A Rolex Forums chart gives 9.75 lignes, a size notation rather than a caliber. One marketplace listing describes a centre-seconds chapter-ring 5013, but its photograph shows no reference stamp or caseback, so that attribution is unverified. These dates and configurations belong to individual records, not production endpoints.

Case measurements in sale records are 35–36 mm. Monaco Legend dates case 412191 to 1945; Christie&#039;s gives circa 1946 for that same case and dates case 493076 to 1946. Other dated examples include Monaco Legend case 411813 (1958) and an unnumbered Antiquorum watch dated to the 1960s. These catalogue dates do not establish a production span. Records show centre-seconds and dual-seconds dials; movement descriptions vary between 10½ and 11 lignes and do not settle a single caliber. See [[Reference:5028|the case and dial record for ref. 5028]].
