DOXA Unveils the SUB 300T Professional Aristera: An Icon for Left-Handed Wearers in a Limited Edition
DOXA continues to innovate in the world of diving watches with the launch of the SUB 300T Professional Aristera, a limited edition of just 300 pieces. This model marks a milestone for the brand: it is the first automatic diving watch specifically designed for left-handed users, with the crown positioned on the left side of the case, offering enhanced comfort and practicality for those who wear their watch on their right wrist.
A New Configuration for a Historic Icon
The SUB 300T is one of DOXA’s most iconic models, first introduced in 1968. Famous for its bright orange dial, which provided greater underwater visibility, it quickly became a reference point for divers due to its distinctive design and technical innovations. The model introduced pioneering features such as a unidirectional bezel for calculating decompression-free dive times and a helium release valve, making the SUB 300T an ideal companion for deep and safe dives.
With the SUB 300T Professional Aristera, DOXA has moved the crown to the left side of the case, making it easier for left-handed users to adjust the watch, without sacrificing the elegance and robustness of the original model. While the crown has shifted to the 9 o’clock position, the date window remains at 3 o’clock, requiring a 180-degree rotation of the movement inside the case. This change demanded special attention to technical aspects, as explained by DOXA’s CEO, Jan Edöcs: “This repositioning required technical adjustments and a revision of the final testing.”

A Design Honoring the Past
The name "Aristera" comes from the Greek word for "left," referencing not only the configuration of the new model but also the roots of the DOXA brand, whose name means "glory" in Greek. The design of the SUB 300T Professional Aristera draws inspiration from iconic elements of DOXA's diving watches, such as the aluminum bezel, a tribute to the 1980s design created by the Aubry brothers. This slightly matte bezel insert gives the watch a refined silver hue.
The case, crafted from 316L stainless steel, is built to resist corrosion, while the scratch-resistant sapphire crystal with anti-reflective coating protects the dial. All dive-related markings, including the hands and indices, are coated with Super-LumiNova® for optimal readability, even in low visibility conditions.
Performance Tailored for Divers
At the heart of the SUB 300T Professional Aristera is a Swiss automatic movement beating at 28,800 vibrations per hour (4 Hz), offering a power reserve of approximately 38 hours. This powerful movement, combined with water resistance of up to 1,200 meters (around 4,000 feet), makes it suitable for the most extreme dives. It also features a helium release valve, an essential function for divers exploring the ocean's depths.
The watch comes with DOXA’s signature orange dial, a symbol of the SUB collection’s pedigree, and can be paired with the legendary "rice bead" stainless steel bracelet or a lighter and more casual NATO-style strap. Both options come with stainless steel buckles.

A Limited Edition Collector’s Piece
In addition to its extraordinary functionality, the SUB 300T Professional Aristera is a true collector’s item. The case back features an engraving of a ship in full sail, raised in reverse to honor left-handed users, along with the inscription "Limited Edition 000/300". With a diameter of 42.50 mm, it is perfect for both underwater adventures and daily wear, confirming it as the ideal watch for travelers and adventurers of all kinds.
In conclusion, the SUB 300T Professional Aristera is much more than just a watch: it is a celebration of DOXA’s technical innovation and timeless design, crafted to meet the needs of those who seek a reliable and unique tool, both at sea and on land.
