Description & Technical Details

Up for auction is a highly coveted icon of Japanese horological engineering: a vintage Citizen "Blackie" Flyback Automatic Chronograph from August 1973. During the 1970s, Citizen competed directly with Seiko in the automatic chronograph race, introducing pioneering case materials and advanced movements. The "Blackie" series utilized an innovative black-coated lightweight alloy construction that gave sport watches a tactical, modern look while remaining incredibly comfortable on the wrist.
Inside this timepiece beats the exceptional In-House Caliber 8100. Unlike most standard chronographs of the era, this movement features a Flyback complication. Originally designed for pilots, the flyback function allows the runner to reset the chronograph hand back to zero and immediately start timing again with a single press of the bottom pusher—bypassing the traditional stop-reset-start sequence.
• The Aesthetics: The contrast between the deep matte black dial, the pitch-black case alloy, and the vibrant orange/yellow hands makes this watch a standout piece of mid-century industrial design.
• The Sub-dial Layout: Emphasizing daily practicality, it uses a clean single-register layout at 6 o'clock to count elapsed minutes up to 30, keeping the rest of the dial clean and highly legible.

Condition Report & Servicing Status

• Mechanical State: Fully operational. The automatic movement winds efficiently, and the time-setting operates as intended. The quick-set functions for the day and date wheel work correctly. The chronograph starts, stops, and resets crisply to exactly 12 o'clock. The advanced Flyback function operates smoothly when the lower pusher is depressed while the chronograph is running. The watch keeps reliable vintage time.
• Cosmetics: In very good vintage condition. The original black "Blackie" case coating is remarkably well-preserved for its age, showing honest, light rubbing and silver-toned minor wear-through along the sharp case edges and corners, which adds authentic vintage character. The stainless steel screw-down back is in excellent condition with crisp, fully legible factory stampings. The dial and hands are in absolutely flawless condition. The mineral crystal is clean, showing only minimal hairline marks under close inspection.
• Note: As with all vintage timepieces, water resistance is not tested or guaranteed. Please keep this historic watch away from direct moisture or water contact.
