Meet the Doxa SUB 300 Beta Steel with New Colors and a Slimmer Silhouette

First introduced in 1967, the Doxa SUB ranks among the most famous historic diver’s watches. With its signature orange dial, the timepiece introduced some groundbreaking features, such as a unidirectional rotating bezel with dual dive time and depth indications to ensure a safe ascent without the need for decompression stops. At the time, divers relied on the US Navy’s no-decompression dive tables as their golden standard for determining how much time they could spend at a given depth and return to the surface without the risk of decompression sickness. Doxa engineers succeeded in integrating the US Navy’s values into the bezel, in orange on an outer ‘depth’ ring, and in black on an inner ‘minutes’ ring. 

The latest addition to the diver’s collection is dubbed “SUB 300β,” with β translating into Beta, meaning a palette of colors and new finishes paired with a subtle bezel redesign for sleekness and an “urban elegance.” Driven by a self-winding Sellita movement, it preserves its core tool watch attributes while embracing a touch of style and sophistication. Adhering to the 42.5mm diameter, Doxa has refined the case design to create a slimmer profile, measuring just 11.95mm (in contrast to the SUB 300T’s 13.65 mm), and reduced the bezel height by 0.5 mm.

The result is a diver’s watch with more streamlined, contemporary proportions. The stainless steel case maintains the water resistance up to 300 meters and the signature unidirectional bezel made from ceramic. The luminescent dial, available in black, blue, and white, features a sunburst finish and a wave motif that plays with light, producing a radiant backdrop while maintaining the functionality.

The SUB 300 Beta is available on a historically inspired beads-of-rice bracelet for $2,290. The variant with a rubber strap has a price tag of $2,250.
