Citizen is commemorating five decades of its pioneering Eco-Drive technology with the introduction of two exclusive limited-edition Promaster timepieces. These new models, inspired by the innovative spirit of 1976 when Eco-Drive was first conceived, blend historical design elements with contemporary watchmaking advancements. The collection showcases Citizen's enduring commitment to sustainable and high-performance horology, offering adventurers and enthusiasts alike a fusion of style and functionality.

The Promaster collection has long been synonymous with rugged reliability and superior performance, particularly for those who explore challenging environments on land, in the air, or at sea. The core of this capability lies in Citizen's proprietary Eco-Drive technology, which harnesses both natural and artificial light sources to continuously power the watches, eliminating the need for battery replacements. This sustainable approach not only underscores Citizen's environmental consciousness but also provides unparalleled convenience and dependability for wearers across the globe. The two anniversary models exemplify this enduring legacy, marrying cutting-edge light-powered movements with thoughtfully curated aesthetics that pay homage to their heritage.

Among the new releases is the limited-edition Promaster Skyhawk, a timepiece that captures the essence of a radiant sunrise with its distinctive light-gold tone casing and bracelet. The watch features a bold black dial that contrasts elegantly with its metallic sheen, housed within a multi-faceted case design that has garnered widespread acclaim in international markets. Equipped with the sophisticated Eco-Drive Radio Controlled Cal. U680 movement, the Skyhawk boasts a unique analog/digital display, a 1/100 chronograph, and a rotating bezel, making it an indispensable tool for pilots. Its commanding 45.7 mm case size and precise lines are signature attributes of the SKY series, ensuring a strong presence on the wrist.

Complementing the Skyhawk is the Promaster Tsuno Chrono, a limited-edition model whose design evokes the classic automobiles of the 1970s. This watch features a rich dark green dial, a refined brown leather strap, and subtle gold-colored accents, creating a stylish retro appeal. At its heart is the Cal. E210 movement, which includes an advanced mechanism that instantly resets the chronograph hands to zero – a feature commonly associated with mechanical chronographs but now seamlessly integrated into an Eco-Drive model. This fusion of vintage aesthetics with cutting-edge functionality delivers a timepiece that is both visually captivating and exceptionally reliable.

These limited-edition Promaster models not only celebrate Eco-Drive's half-century milestone but also reinforce Citizen's position at the forefront of watch innovation. By combining sustainable technology with designs that resonate with both contemporary tastes and historical appreciation, Citizen continues to craft timepieces that meet the diverse needs of modern explorers while honoring its rich heritage of excellence.
