The 2940 is the wartime Bubbleback. Introduced around 1940 and produced through 1949, it spans the years when Swiss watch production had to keep running while Europe burned, and the commercial catalog had to keep selling while most of its traditional markets closed. Rolex met the moment with a two-piece Oyster that kept to the form the 3131 established four years earlier but pushed it toward volume production in steel. Where the 3131 was a precious-metal statement reference, the 2940 was the version that went to war. It came in stainless steel, with center sweep seconds and a dial catalog wide enough to suit whatever market still took delivery. It is also the reference that sits at the center of the “hooded lug” forgery problem that continues to haunt Bubbleback authentication. | The 2940 is the wartime Bubbleback.

Two-tone contrasting-zone dials divide the dial into inner and outer zones with contrasting finishes, typically a silver outer zone with a darker inner track or vice versa. The two-tone layout traveled across several contemporaneous references and appears on the 2940 in examples dated to 1942 and the surrounding years. | Two-tone contrasting-zone dials divide the dial into inner and outer zones with contrasting finishes, typically a silver outer zone with a darker inner track or vice versa.

Salmon | Salmon-finish dials are scarcer still. The Heritage Auctions “Two Tone Salmon Dial” example, a c.1942 2940, is the best-documented salmon dial in the public auction record, and any appearance at auction or dealer inventory draws collector attention disproportionate to the reference's general market position. | ||
Silvered and champagne-finish dials with applied hour markers and a minute track represent the baseline dress-watch configuration for 2940s sold to retailers who did not specify a more unusual dial treatment. These are the most commonly surfaced dial type in dealer inventory. | Silvered and champagne-finish dials with applied hour markers and a minute track represent the baseline dress-watch configuration for 2940s sold to retailers who did not specify a more unusual dial treatment.

Original-dial diligence is non-trivial. Refinished dials outnumber original dials in the surviving population. Eight decades of service activity have given plenty of opportunity for radium replacement, re-lacquering, and full refinishes, and the refinishing industry in the mid-to-late twentieth century was proficient enough that a well-executed refinish can be difficult to detect. The indicators that matter: radium patina matching between dial and hands, printing sharpness consistent with 1940s-era dial manufacturing, correct font choices for the era (which refinishers often subtly miss), and the absence of refinisher signatures or marks on the dial back. Provenance documentation (auction-house lot photography, extract from Rolex archives for later references, retailer paperwork) helps but is rare for 2940s. | Original-dial diligence is non-trivial.

Any 2940 offered with hooded lugs should be treated as an aftermarket modification unless the seller can produce clear between-lug 2940 stamping along with professional authentication from a recognized vintage Rolex specialist. The reference's authentic configuration is squared-off inner lugs. | |||
Case material verification matters at the high end of the market. 14K gold-top/steel and 9K solid gold examples carry substantially different value positions from steel 2940s, and hallmark photography is non-negotiable on any precious-metal listing. Cases that have been replated, regilded, or otherwise worked should be identified as such, and the premium a solid gold case commands should survive the verification step to be worth paying. | Case material verification matters at the high end of the market. 14K gold-top/steel and 9K solid gold examples carry substantially different value positions from steel 2940s, and hallmark photography is non-negotiable on any precious-metal listing.
