The Hanhart Aquasphere Ocean Fade presents a compelling technical package for the modern dive watch enthusiast. Departing from the brand’s vintage-inspired chronographs, this timepiece is engineered from the ground up as a robust, purpose-built instrument, defined by its specifications and material choices.
Case Specifications and Dimensions
The Aquasphere is built upon a stainless steel case measuring 42mm in diameter, with a lug-to-lug distance of 49mm and a thickness of 12.95mm. These dimensions are notable given its 300-meter water resistance rating, achieved with a screw-down crown protected by integrated crown guards. The architecture includes recessed lugs that flow cleanly into the midcase, a design element derived from the Primus collection but executed with more refinement. A helium escape valve is also included, a feature specified for saturation diving applications. The unidirectional rotating bezel is fitted with a highly scratch-resistant ceramic insert, featuring a lumed triangle and minute track.
Engineering and Mechanism Analysis
At its core is the Swiss automatic Soprod P024 caliber, a movement mechanically based on the ETA 2824 architecture. Operating at a frequency of 28,800 vibrations per hour (4 Hz), it offers a 38-hour power reserve. Critically, Hanhart utilizes the “Top” execution of this movement and performs in-house regulation to a stringent standard of 0 to +8 seconds per day across six positions. This level of adjustment ensures a high degree of chronometric performance straight from the factory, elevating the base caliber significantly.
Materials and Durability
The watch is designed for legibility and resilience. A sapphire crystal protects the dial, which features applied indices and a segmented handset treated with luminous material for low-light visibility. The attachment systems prioritize versatility. The steel bracelet uses a non-proprietary quick-release spring bar system, allowing easy swaps. Alternative options include a fitted rubber strap with integrated quick-release tabs and a military-grade elastic webbing Hook Strap. While the current bracelet clasp lacks a tool-less micro-adjustment system, the overall construction quality is consistent with the watch’s tool-oriented design.
In conclusion, the Hanhart Aquasphere’s technical value is found in its synthesis of a durable, well-proportioned case, the use of performance materials like ceramic and sapphire, and the meticulous in-house regulation of its Swiss automatic movement. It is a well-engineered diver that successfully merges Hanhart’s German design principles with contemporary technical standards.
