Citizen launched its vertical-clutch column wheel 8110 chronograph in 1972, which makes this just serviced and all original near new-old stock PVD example - a legitimately rare 8110 variant - one of the first made, and its compact movement has a high beat, running at 28,800 beats per hour.  Of note, the 8110 movement was Citizen’s answer to Seiko’s famed 6139 movement, but Citizen’s well designed 8110 – unlike the 6139 - featured hand winding and ‘flyback’ – which allows the wearer to zero the chronograph whilst it’s running, rather than having to stop it first, then restart.  This permits an instant stop and re-start of the chronograph function.

The compact design of the 8110 movement allowed smaller casing, so the 8110 tends to be lighter than, for example, the 6139 (which did not have a flyback feature) chronographs of the period.  All models have the column wheel/vertical clutch design. These movements have quick setting mechanisms for date and day. Both are set when the crown is pulled out one click – the date by rotating the crown, the day by pressing the reset button.


Compared to modern chronographs, the only chronographs in today’s market with similar features and construction sell at a far higher price point – such as Blancpain, Vacheron Constantine, Patek, and Audemars. The 8110’s are the least expensive, yet most sophisticated chronograph ever made!

This Citizen chronograph comes with a PVD-coated stainless-steel bracelet, nylon NATO strap, spring bar tool, and Pelican travel case.

  • DIAL: Original Citizen-signed black dial with original minute, hour, and chronograph hands. This dial is rather sharp - and distinctly 1970s - in its design, which includes spectacular contrasting colors in its highly unique subdial design.


    CASE: Black PVD-coated nickel Citizen 38mm x 44mm (with crown) case, with stainless steel caseback - PVD on case is flawless, with no wear evident anywhere on the case, truly a remarkable, nearly fifty year-old example. The case also features hooded lugs.


    CRYSTAL: Crystal is scratch and blemish-free.


    STRAP: This Citizen comes with a black PVD-coated stainless-steel bracelet, which fits a 7" wrist - although it's not original to the watch, it matches it quite nicely.  This Citizen also comes with a black nylon NATO strap – a nice sporty complement to the 8110's classic vintage styling.


    MOVEMENT: Original Citizen 23-jewel automatic movement, manufactured in August 1972. The 8110 flyback tachymeter movement can be wound either manually or automatically. Separately, the date and day - with Kanji Japanese/English calendar variants – rotate and set as designed.  This watch received a full service in April 2020.


    CROWN: Original "CTZ"-signed crown.


    CHRONOGRAPH PUSHERS: Chronograph pushers depress with satisfying click, no stick. All chronograph hands snap back and reset to zero with no issue!
