This serviced Rare Vintage Citizen Eco-Drive Chronograph Tank Ref. H501-S112828 is a spectacular example of Japanese design sophistication, embodying the elegant art-deco Tank silhouette and advanced light-powered quartz engineering of Citizen's contemporary heritage lines. It is driven by the highly regarded Citizen Caliber H501 Eco-Drive solar movement, an innovative high-precision engine powered by any light source to deliver remarkable timekeeping accuracy without the need for regular battery changes. Following a full mechanical service and checkup, the caliber operates with optimal efficiency, providing seamless chronograph timing functionality, a 24-hour subdial register, and crisp date operation that established the Eco-Drive line's renown.
The face of the watch features a stunning, factory-original chocolate brown dial enriched with multi-textured guilloché patterning that captures light with sharp precision across its multi-layered surface. A discreet date window sits neatly between 4 and 5 o'clock, perfectly integrated alongside the three chronograph subdials to maintain the sophisticated symmetry of the layout. It is beautifully appointed with an applied rose gold-toned Roman numeral at 12 o'clock, applied hour batons, a refined outer railroad minute track, and matching faceted hands, adding incredible legibility, warm contrast, and luxurious executive depth to the rich mocha background.
The rose gold-toned rectangular Tank case is beautifully preserved, retaining its sharp factory geometry, polished bezel flanks, and streamlined lug contours that sit comfortably on the wrist. Emphasizing its refined chronograph architecture, this reference features clean rectangular pushers flanking the crown at 2 and 4 o'clock, perfectly complementing the balanced proportions of the case. The timepiece remains 100% authentic, complete, and unaltered, retaining its original factory dial, hands, crystal, case, crown, pushers, and original textured brown leather strap with white contrast stitching to meet the strict standards of discerning enthusiasts.
Collectors and enthusiasts pursue vintage-inspired Citizen Tank chronographs for their rare rectangular geometry, warm rose-tone palette, and reliable solar-powered convenience. While many dress chronographs feature standard round cases, this pristine, fully original specimen complete on its factory strap offers a rare opportunity for collectors who appreciate timeless art-deco aesthetics paired with effortless modern engineering, a refined and distinctive cornerstone ready for any serious watch collection.
