Doxa SUB 4000T Sharkhunter 875.10.101.10

The DOXA SUB 4000T Sharkhunter Ref. 875.10.101.10 is an imposing professional dive watch that represents a more modern and technical evolution of DOXA’s legendary SUB design. Its substantial 316L stainless steel case measures 47.5mm x 48mm and features a distinctive asymmetric profile with an integrated crown protector. The black “Sharkhunter” dial retains DOXA’s unmistakable high-visibility layout, with oversized Super-LumiNova-filled markers and the brand’s characteristic compact hour hand, while a power-reserve indicator provides an additional layer of functionality rarely found on a professional diver. A sapphire crystal with anti-reflective coating, DOXA’s patented unidirectional dive bezel, integrated helium-release valve, screw-down crown, and an exceptional 1,200-meter / 4,000-foot water-resistance rating make the SUB 4000T a serious saturation-diving instrument. This steel-bezel Sharkhunter configuration was produced as part of a limited-edition SUB 4000T series.

Inside is the Swiss automatic ETA 2897, a 21-jewel movement based on the proven ETA 2892 architecture and modified to incorporate the prominent power-reserve display. The movement operates at 28,800 vibrations per hour and provides roughly 42 hours of usable power reserve, alongside central hours, minutes and seconds and a quick-set date at 3 o’clock. The SUB 4000T was an important departure from DOXA’s more traditional SUB 300/300T-derived designs, introducing a larger, more ergonomic case while retaining the brand’s core professional-diving DNA. With its massive depth rating, helium valve, power-reserve complication, black Sharkhunter dial and imposing stainless steel construction, the 875.10.101.10 stands as one of the most technically ambitious and distinctive DOXA divers of its generation.

DOXA, founded in 1889 by Georges Ducommun in Le Locle, Switzerland, has a rich history of watchmaking innovation. Initially gaining recognition for its pocket watches and dashboard clocks, DOXA's defining moment came in 1967 with the introduction of the SUB 300 dive watch. This groundbreaking timepiece, featuring an iconic orange dial, unique no-decompression bezel, and purpose-built design for recreational divers, quickly became a benchmark in the industry. Notably, in collaboration with Rolex and the introduction of the Sea-Dweller, DOXA co-developed the now-common helium escape valve concept, adding another feather in its cap as a true diver’s tool in its day. DOXA's reputation was further enhanced by its association with Jacques-Yves Cousteau and its frequent appearance in Clive Cussler's adventure novels.

Despite facing challenges during the quartz crisis, DOXA experienced a resurgence after its acquisition by the Jenny family in 1997. Today, the brand continues to honor its diving heritage while embracing modern watchmaking techniques. DOXA's journey from a small Swiss workshop to a globally recognized dive watch manufacturer demonstrates its enduring commitment to innovation, quality, and functionality. The brand's iconic designs, particularly the SUB series, remain popular among diving enthusiasts and watch collectors alike, cementing DOXA's place in horological history.
