Oris Divers Sixty-Five Caliber 400

In the vast ocean of horological offerings, few brands capture the spirit of adventure and craftsmanship quite like Oris. From its humble beginnings in the Swiss Jura Mountains to its current status as a respected independent watchmaker, Oris has consistently pushed boundaries while staying true to its core values. The brand's latest creation, the Divers Sixty-Five Calibre 400, is a testament to this unwavering commitment to innovation and tradition.

Founded in 1904 by Paul Cattin and Georges Christian, Oris quickly established itself as a manufacturer of high-quality pocket watches. By the 1930s, the company had expanded its repertoire to include wristwatches, gaining recognition for its pilot's watches during World War II. In the post-war era, Oris continued to evolve, embracing the burgeoning dive watch trend with the introduction of the original Divers Sixty-Five in 1965.



The Divers Sixty-Five was a groundbreaking watch for its time, featuring a robust stainless steel case, a unidirectional rotating bezel, and a legible dial with luminous markers. Its vintage-inspired design, reminiscent of the golden age of scuba diving, resonated with watch enthusiasts and adventurers alike. The watch's popularity soared, cementing its place as a cornerstone of Oris's collection.

Fast forward to the present day, and the Divers Sixty-Five remains as relevant as ever. Its classic aesthetic, combined with modern technological advancements, has made it a favorite among collectors and casual wearers. The latest iteration, the Divers Sixty-Five Calibre 400, builds upon this legacy, offering a harmonious blend of heritage and innovation.

The green dial, reminiscent of the ocean depths, is adorned with luminous hour markers and hands, ensuring optimal visibility in low-light conditions.



The watch's most significant upgrade, however, lies within its mechanical heart. The Calibre 400, an in-house movement developed by Oris, represents a new standard in automatic watchmaking.
