The DOXA SUB 600T line is a celebrated collection of Swiss-made diving watches, known for its robust functionality and distinctive design. Originally introduced in the 1980s during the "Aubry Frères era" of DOXA, the SUB 600T distinguished itself with a more angular, blocky case shape compared to the brand's earlier cushion-cased models. This design, featuring a crown typically positioned at 4 o'clock, offered a fresh aesthetic while maintaining the brand's commitment to serious diving tools. Key features of the SUB 600T series include a water resistance of 600 meters (1,970 feet), a unidirectional rotating bezel with DOXA's signature US Navy no-decompression dive table (available with either stainless steel or ceramic inserts), and highly legible dials with luminescent markers, including the distinctive "shark tooth" indices at 3, 6, 9, and 12 o'clock on many variations. Modern iterations of the SUB 600T, often powered by reliable Swiss automatic movements like the Sellita SW200-1, come in a variety of vibrant dial colors that are a hallmark of the DOXA brand, such as the iconic Professional orange, Sharkhunter black, Searambler silver, Caribbean blue, Divingstar yellow, and Aquamarine turquoise. These watches are available with stainless steel bracelets or color-coordinating NATO or rubber straps, offering versatility for both diving and daily wear.
DOXA itself is a historic Swiss watch manufacturer with a legacy dating back to its founding by Georges Ducommun in 1889 in Le Locle, Switzerland. Initially recognized for its pocket watches and dashboard clocks for automobiles and aircraft, including the patented 8-day DOXA Caliber, the brand made a pivotal shift in the 1960s to specialize in diving watches. This new direction culminated in the 1967 release of the iconic DOXA SUB 300, a watch developed in collaboration with diving legend Jacques-Yves Cousteau and U.S. Divers. The SUB 300 introduced groundbreaking features for the time, most notably its bright orange dial for enhanced underwater visibility and the patented rotating bezel with the US Navy no-decompression dive table. These innovations cemented DOXA's reputation as a producer of reliable, professional-grade dive watches. Despite facing challenges during the quartz crisis of the 1970s and 1980s, which saw changes in ownership, DOXA was revitalized in 1997 by the Jenny family, who were also renowned for their expertise in dive watch manufacturing. Today, DOXA continues to be highly regarded by diving professionals and watch enthusiasts alike for its commitment to quality, durability, distinctive designs, and rich heritage in the world of underwater exploration.
