The 2940 is the volume wartime Bubbleback. The 3131 and its sweep-seconds twin 3132 had proven in 1936 that the two-piece Oyster could be manufactured at scale; the 2940 is the reference that made the same case architecture available in steel and inexpensive gold cap. It carries the sweep-seconds configuration that the 3132 pioneered, a center-mounted seconds hand running off Cal. 9¾''' rather than a subsidiary register at 6, and pairs it with a case sized for a masculine wartime wrist. Production runs from roughly 1940 through 1949, with the concentrated peak falling in the five years from 1942 through 1947.

The 2940 uses the two-piece case architecture the 3131 introduced in 1936: a round mid-case with the bezel integral to the case middle, closed at the back by a screw-down caseback that threads directly into the case. No separate bezel ring. No discrete movement-holder. The case measures 31–32mm in diameter with a lug-to-lug of roughly 38–38.5mm and a lug width between 16 and 17mm. The bezel is smooth and domed, polished, unmarked, set slightly proud of the crystal aperture.

The 2940 carries the widest dial catalog of any Bubbleback reference. Some of this breadth reflects Rolex's pre-war practice of configuring dials to retailer specification; some of it reflects the reference's long production run across multiple export markets; some of it reflects refinishing activity over the subsequent eight decades.

The 2940 trades primarily through specialist dealer inventory and the secondary auction market rather than at major Geneva houses. Phillips and Heritage have handled examples; Sotheby's and Christie's have occasionally included 2940s in mid-tier vintage lots; Antiquorum and Bonhams have listed them in catalog sales. The bulk of market activity happens through vintage Rolex specialist dealers, forum-adjacent private sales, and platforms like Chrono24 and 1stDibs. Price discovery is accordingly uneven, and a given configuration can trade at widely varying prices depending on venue and market conditions.
