Oris Aquis Date Calibre 400 Blue Dial Men’s Watch – Model

Product Overview

The Oris Aquis Date Calibre 400 Blue Dial Men’s Watch is a precision-engineered Swiss timepiece built for those who demand both performance and style from their wristwear. As part of the respected Aquis collection, this model exemplifies Oris’s commitment to diving heritage and mechanical innovation. At its heart lies the in-house Calibre 400 automatic movement—developed entirely by Oris—delivering a remarkable 120-hour (5-day) power reserve and exceptional resistance to magnetic fields, rated up to 2,500 gauss. This makes the watch highly reliable in environments where electronic interference could disrupt lesser movements, such as near MRI machines, power tools, or modern office equipment.

The watch features a bold 43.5mm stainless steel case with a striking blue sunray dial that catches the light beautifully while maintaining excellent readability. Applied hour markers and generously coated luminescent hands ensure visibility in low-light conditions, whether underwater or during nighttime wear. A practical date window at 6 o’clock adds everyday utility without compromising the dial’s balanced symmetry. The unidirectional rotating bezel, fitted with a scratch-resistant ceramic insert and 60-minute graduations, allows divers to monitor elapsed dive times safely—a critical function for underwater safety. Its precise click mechanism offers tactile feedback and secure operation, even when wearing gloves.

Protected by a domed sapphire crystal with anti-reflective coating, the dial remains clear and glare-free in bright sunlight or underwater. The case back is solid, emphasizing durability and water resistance, which is rated to 300 meters (30 bar) and compliant with ISO 6425 standards for dive watches. This certification confirms rigorous testing for water resistance, legibility, shock resistance, and reliability under pressure—ensuring the watch performs reliably in real-world diving conditions.
