Jeager LeCoultre’s Reference E 2643 was launched in the late 1960s and was marketed as the “Shark Deep Sea” in the U.S., and as the “Vogue Chronograph” in Europe. The “LeCoultre” signed-dial on this example indicates that it was made for the American market. This unusual diving chronograph is housed in a massive case measuring 40 mm in diameter. Featuring broad, angular lugs, the masculine lines and case dimensions, combined with its modern styling, make it difficult to believe this watch is nearly a half-century old. The matte black dial featuring a tachymeter scale along the outer edge, with its white sub-dials, gives it a sporty aesthetic with great legibility. The present watch can be considered a chameleon, as the watch can adapt to the wearer's needs by changing the bezel. Swapping the fitted telemeter bezel with the additional, supplied 60-minute bezel, the watch can be used for more casual wear. With the world time bezel, it becomes a great travel watch. This early example of LeCoultre’s “Shark Deep Sea” is further enhanced by its original, excellent condition. Accompanied with its original presentation box that prominently presents the supplied alternative bezels, it’s a rare and uncommon ensemble for the collector.
