Citizen Crystal 7 Mechanical Day Date automatic black dial steel bracelet 40 mm

Citizen Crystal Seven, a reinvented heritage

Launched in 1965, the Crystal Seven made watchmaking history with its bold design and technical innovations. By placing the day display at the top of the dial, Citizen challenged established codes and offered a watch that was both elegant and functional. The choice of mineral glass, a first for a Japanese watch, guaranteed greater resistance to scratches, hence the name. Today, the C7 collection pays tribute to this iconic model with its distinctive lines and atypical positioning of the day window. With particularly attractive value for money, this re-edition continues Citizen's heritage while appealing to a new generation of watch lovers, keen to wear a piece of history on their wrist.

The design

The design of the NH8391-51EE is a true tribute to timeless aesthetics. The 40.2 mm stainless steel case (13 mm thick) features sporty-chic lines and an exemplary finish. The plain black dial features a “crosshair” design, with lines running from the center to the edge of the dial, dividing it into four quadrants. This design is typical of watches from the 1960s! The dial features faceted applique hour-markers and the unusual heptagonal shape of the day window opening. Luminescent “Alpha” hands provide excellent legibility. A flat mineral glass protects the whole.

This version is adorned with a 3-link, fully satin-finished steel bracelet, which harmoniously completes the ensemble, while ensuring optimal everyday comfort.
