Longines Legend Diver Ref. 7150-2

Partially verified

This Longines Legend Diver reference 7150-2 is an automatic-winding wristwatch featuring a 41mm 'Super Compressor' case design manufactured by EPSA. The watch is distinguished by an internal rotating timing ring, operated by a crown at the 2 o'clock position, while a second crown at 4 o'clock provides time-setting functionality. The dial has aged to a caramel 'tropical' tone with gold-tone indices and darkened luminous plots. The watch is equipped with a matching 'shovel' handset. Internal power is provided by the Longines Caliber 290 automatic movement. An extract from the Longines archives accompanies this timepiece, documenting its original sale in 1964 in Venezuela. The case is described by the vendor as unpolished.

Object description

Case and Dial

The watch is housed in a 41mm 'Super Compressor' case, a design produced by EPSA. It departs from traditional external dive bezels by incorporating an internal rotating timing ring controlled via the crown at 2 o'clock. The time-setting crown is located at the 4 o'clock position. The case is described by the vendor as unpolished.

The dial exhibits a 'tropical' caramel discoloration, with indices that have developed a gold-tone patina. The luminous plots are darkened, and the piece retains a matching 'shovel' handset, consistent with the design elements of this reference.

Movement and Functionality

The watch is powered by the Longines Caliber 290, an automatic-winding movement. This caliber was used during the mid-20th century when the company was known for developing in-house technical components.

Functionality is divided between the two crowns, with the upper crown controlling the internal rotating ring and the lower crown controlling the hands for time adjustment.
