Reference:3937: Difference between revisions

The 3937 is the last rectangular Prince. Christian Wass's collector record on Watchprosite calls it bluntly: "the last case model issued by Rolex" for the Prince family — a 1938 introduction with flowing scroll lugs that period collectors and modern dealers nicknamed "Rams Horn" or "Scroll Lug" for their Art-Nouveau-influenced curves. The case is a rectangular brushed-and-polished form, distinct from the flared Brancards (971, 1490, 1491) and the stepped Railway (1527) and the asymmetric Aerodynamic (3361 / 3362). It runs 1938 through approximately 1952, and the production tail dovetails with Rolex's catalog migration to the round Oyster Perpetual platform — when 3937 production ends, the Prince as a category of dress watch effectively closes (the 2005 Cellini Prince revival sits on a different platform). The reference's defining association is the '''Eaton 1/4 Century Club''' retailer program. The T. Eaton Company of Toronto established the Quarter Century Club in 1919 as a 25-year-service award for employees; from approximately 1930 the program issued Rolex watches as the canonical men's gift, and 3937 became the program's reference of choice from approximately 1944 through 1952, after the 1490 stock that had supplied the program through 1944 was exhausted. Eaton-presentation 3937s carry "EATON" in place of "ROLEX" on the dial and a caseback inscription naming the recipient and bracketed by the start and presentation years of service. Confirmed Eaton recipients include Sidnet Garbett (1926–1951, Sotheby's NY 2020 lot 73), Donald M. Bird (1926–1951), and Fred W. McMackon (1928–1953). The 3937 is rare in the modern auction record — fewer than twenty distinct lots surfaced across surveyed houses — and Phillips, Sotheby's specialist sales, and Christie's specialist sales carry no 3937 lots, consistent with the reference's Canadian-market retailer-program origin.

==Core facts==

==Where it sits in the line==

The 3937 closes the Prince story. The flared Brancards launched the line in 1928 (971 first, 1490 the canonical larger Brancard, 1491HS the rare jumping-hour); the straight-sided Classics (1862) and the stepped Railway (1527) ran in parallel through the 1930s; the Aerodynamic 3361 / 3362 introduced the asymmetric wedge case at the 1939 Swiss National Exhibition. The 3937 launches at approximately the same time as the 3361 — 1938 versus 1939 — but takes a different design direction. Where the 3361 carries an asymmetric wedge profile and a relief escutcheon at six replacing sub-seconds, the 3937 keeps the standard Prince duo-dial layout and replaces the case ornamentation with the flowing scroll lugs that give the reference its "Rams Horn" nickname. The 3937 is the simpler, more practical late-period Prince — and the reference Rolex chose to keep producing for the Eaton account in Canada when European retail demand for the rectangular Prince had moved on.

==Eaton 1/4 Century Club — the canonical 3937 configuration==

The 3937's defining association is the Eaton presentation watch. The dial dispenses with the Rolex wordmark and replaces it with "EATON" in the same applied-text position; the dial typically reads "EATON" + a date-bracketed inscription text such as "1/4 CENTURY CLUB" or "Quarter Century Club" within the dial face. This is a near-unique configuration in Rolex production — almost no other Rolex reference carries a retailer-replacing-Rolex dial signature; standard retailer doubles add the retailer name beside the Rolex wordmark rather than replacing it. The Eaton dial-replacement convention reflects the program's Canadian-employee-recognition framing rather than a commercial co-branding arrangement.
