The 2764 is a mid-to-late-run member of the second-generation Bubbleback family, the generation that begins with the two-piece case transition of 1936 (refs 3131 and 3132) and continues through the post-war period until the flat-caseback architecture of Cal. 1030 arrives in 1950. The 2764's earliest documented case is Heritage's example numbered 107524; the Phillips Geneva Watch Auction THREE lot (case 107118) is dated 1941. The observed serial range, paired with the mature two-piece Oyster case and the 620-family movement, places production in a window roughly 1937 through 1948. | The 2764 is a mid-to-late-run member of the second-generation Bubbleback family, the generation that begins with the two-piece case transition of 1936 (refs 3131 and 3132) and continues through the post-war period until the flat-caseback architecture of Cal. 1030 arrives in 1950.

The 2764 case is a two-piece Oyster. Smooth polished fixed bezel, mid-case with the Bubbleback's characteristic domed caseback screwed directly into it, with no separate movement-holder ring (that generation of construction ended in 1936). The screw-down crown maintains the Oyster's waterproof claim; the acrylic crystal rides above the dial. | The 2764 case is a two-piece Oyster.

The 2764 produces a wider dial variety than most single Bubbleback references of the period, partly because the production window ran over a decade and partly because the reference carried multiple retailer variants, each with its own dial configuration. | The 2764 produces a wider dial variety than most single Bubbleback references of the period, partly because the production window ran over a decade and partly because the reference carried multiple retailer variants, each with its own dial configuration. | ||

The Phillips 2016 result at CHF 31,250 is the current public-auction benchmark for a strong-configuration 2764. Clean stainless examples with "SUPER PRECISION" and period-correct hardware anchor roughly CHF 10,000–25,000 depending on condition and dial. Zell Bros and Birks retailer signatures push into the CHF 20,000–35,000+ range when paired with strong condition. | The Phillips 2016 result at CHF 31,250 is the current public-auction benchmark for a strong-configuration 2764.
