CITIZEN ECO-DRIVE PROMASTER DEPTH METER CHRONOGRAPH REF. BJ2115-07E: IDENTIFICATION

A high-performance ISO-compliant professional diving watch featuring Citizen's Eco-Drive B741 solar movement. The dial is characterized by a sunray-textured black base with three sub-dials: a 24-hour indicator at 9 o'clock, a 50-minute chronograph counter at 12, and a constant seconds hand at 6. The prominent blue handset includes a depth meter needle calibrated for 0 to 50 meters. The 48mm case includes a large electronic sensor at 9 o'clock for depth measurement and a unidirectional 60-click elapsed time bezel. The piece is fitted on an integrated black polyurethane strap with a steel buckle.

Citizen introduced the Promaster series in 1989 as a dedicated line for professional sports enthusiasts, with the Aqualand series pioneering electronic depth sensor integration in 1985. This specific reference, BJ2115-07E, utilizes the proprietary Eco-Drive technology, first commercialized by Citizen in 1976 as the Crystron Solar Cell, which eliminates the need for battery replacements by converting any light source into energy. This model reflects the mid-2000s trend toward oversized 'tool' watches, prioritizing underwater legibility and tactile operation with gloves.

KEY EVIDENCE

CONDITION & GRADE

Good (Grade 80-84%)

Grading breakdown

The rating reflects clear bezel wear (scratches to the black coating) and crystal marks, though the dial and hands remain in excellent, non-degraded condition.

Condition

Visual evidence shows moderate scuffing on the ion-plated bezel edge and minor abrasions on the mineral crystal near the 12 o'clock sub-dial. The polyurethane strap exhibits surface dust but no visible 'blooming' or cracking at the lug integration points.
