== Late small Bubbleback examples ==

Auction catalogues date individual ref. 5002 watches from circa 1945 to circa 1952, and ref. 5006 examples from 1948 into the 1950s. 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. Christie’s describes its circa-1940 ref. 6006 as a Bubble Back. Later Christie’s and Antiquorum catalogues document gold examples dated 1952–55, with both central and subsidiary seconds. The 1952 Antiquorum watch is case 927300, with Cal. 520 and a restored subsidiary-seconds dial. These lot dates do not establish production boundaries. See [[Reference:6006|the 6006 record]].

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 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. Ref. 5052 appears in two case-numbered auction records: Christie’s describes pink-gold case 653977 as self-winding and dates it to the 1940s; Stockholms Auktionsverk dates steel case 663654 to the 1950s. Both records give 32 mm. The available examples do not establish a production span or numbered caliber. See [[Reference:5052|the 5052 article]]. These dates and configurations belong to individual records, not production endpoints. Christie’s describes its circa-1940 ref. 6006 as a Bubble Back. Later Christie’s and Antiquorum catalogues document gold examples dated 1952–55, with both central and subsidiary seconds.
