About this watch

The Doxa SUB 300T Aquamarine is a statement piece that combines functionality, style, and rich history. This Swiss watchmaker's exceptional diving watches since the 1880s have earned a solid reputation among collectors. The SUB family of watches is celebrated for its robust features designed specifically for underwater exploration. At the core of the SUB 300T is the reliable ETA caliber 2824-2 automatic movement, featuring a frequency of 28,800 vibrations per hour and a power reserve of 42 hours. The watch's captivating aquamarine color reflects the depths of the ocean, while its matte finish gives it a modern edge. The dial features stick and dot indexes for readability in various conditions, complemented by stick hands. A date function is strategically placed without cluttering the dial. The rotating bezel ranges from 0 to 60, adding to the watch's rugged aesthetic. Crafted from sapphire glass, this timepiece strikes a balance between presence and wearability.
