Aquis Titan

The Oris Aquis Titan brings a distinctive edge to the Aquis line, pairing the brand’s proven diver DNA with a lightweight yet durable titanium case. Originally introduced for those seeking a more wearable, corrosion-resistant alternative to traditional steel, the Titan has found favor among serious dive watch fans and collectors alike. Its utilitarian appeal is enhanced by a purposeful design and a reputation for reliability in challenging environments.

Key references such as the 733 7653 4155 and its variations are powered by the Oris 733 automatic caliber, based on the Sellita SW200-1, offering a 38-hour power reserve and smooth operation. Case sizes typically range from 43mm to 46mm, making wrist presence a consideration—smaller-wristed buyers may prefer earlier, slightly slimmer variants. Water resistance is a robust 300 meters across the line, and the integrated bracelet or rubber strap options are both comfortable and secure for daily wear or diving.

Price variation between references is driven by factors like dial color, bezel material (ceramic vs. steel), and condition—full set examples with original box and papers command a premium. Special editions and limited runs can also attract higher prices, particularly those with unique dial textures or commemorative casebacks. When shopping, focus on bracelet integrity and the condition of the titanium surfaces, as they can show wear more readily than steel; replacement links and OEM straps are available but can be costly.
