A Navanos watch does not begin with aesthetics.
It begins with a question: what must this instrument achieve? Every material selected, every tolerance specified, every test conducted flows from the answer to that question. Design follows function. Beauty follows purpose.
This is how the Ravaro Diver was built. This is the Navanos way.
The Objective Comes First
For the Ravaro, the objective was unambiguous, a true professional-grade dive instrument. Not a watch that looks the part. A watch that performs it.
That meant exceptional water resistance. Legibility in any condition. Shock resistance. Advanced protection against magnetic fields. And the documentation to prove every single one of those claims independently.
With the objective defined, everything else follows.
Engineering Feasibility - Switzerland
With our objectives set, we engage a specialized engineering firm in Switzerland. Concepts are shared. A thorough feasibility study begins.
This stage involves advanced simulation testing, modeling the watch under extreme pressures, magnetic exposures, thermal stress, and G-force impacts. These virtual tests reveal potential weaknesses long before a single physical component is produced. Problems are solved with data, not guesswork. The design is refined until the engineering confirms what the objective demands.
Technical Design - Biel, Switzerland
Validated findings move to H-Development in Biel, our technical design partner. Here the Ravaro takes precise shape.
Every dimension is calculated to meet the full requirements of ISO 6425. The international standard for professional dive watches. Minimum 100 meters depth resistance, tested at 125% overpressure. Shock resistance. Thermal stability. Legibility in total darkness.
Simultaneously, our advanced antimagnetic architecture is developed in direct collaboration with Systron EMV in Durnten, Switzerland. The result is a progressive magnetic field resistance system that goes well beyond the ISO 764 baseline of 4,800 A/m, engineered to protect the movement against the magnetic interference of both everyday life and extreme environments.
Manufacturing- ISO 2768-F Tolerances
Finalized blueprints move to production. Manufacturing adheres strictly to ISO 2768-F ,the highest fine-tolerance class in professional watchmaking.
Critical linear dimensions are held to variances as tight as ±0.05mm. These tolerances are not a detail, they are the difference between a gasket that holds at 400 meters and one that doesn't. Between a bezel that performs and one that merely looks the part. Precision at this level guarantees flawless component fit, structural integrity, and reliable water resistance under real pressure.
Prototyping - The Human Test
Engineering must ultimately meet the human wrist.
Initial prototypes are evaluated by a carefully selected group of experienced divers, watch enthusiasts, and everyday wearers. Wrist feel. Bezel action with and without gloves. Lume visibility in genuine low-light conditions. Crown operation. Overall ergonomics. Every element of real-world usability is examined, challenged, and refined.
The watch that passes this stage is both engineered and lived in.
TIMELAB Geneva - Independent Certification
Prototypes then travel to TIMELAB in Geneva, the independent Swiss laboratory entrusted with the prestigious Geneva Seal.
There, the Ravaro undergoes comprehensive ISO 6425 verification. Extreme pressure simulation. Condensation and thermal shock testing. Saltwater corrosion resistance. Shock impacts equivalent to a heavy hammer strike. TIMELAB also conducts progressive magnetic field resistance testing — confirming the Ravaro's antimagnetic performance well above baseline standards.
This is not internal testing. This is not self-certification. This is independent, impartial, documented proof confirmed where it matters, by those with no stake in the outcome.
Metrology Laboratory — Dimensional Verification
Nothing is left to assumption.
Following certification, the watch is fully disassembled and sent to a specialized metrology laboratory. State-of-the-art measuring equipment verifies every dimension against ISO 2768-F tolerances — flatness, straightness, perpendicularity, and more. A detailed, traceable report is generated confirming that every component meets the standard precisely.
The documentation exists. It is real. It is available.
This Is the Navanos Way
Researched, designed, and tested in Switzerland, this process is deliberate, meticulous, and non-negotiable.
It is not the fastest way to build a watch. It is not the cheapest. But it is the only way to build one we are genuinely proud of and the only way to deliver an instrument that earns the trust of those who wear it.
When you choose a Navanos watch, you are not purchasing a claim. You are acquiring a documented, independently verified precision instrument, engineered for reliability, tested beyond expectation, and built to perform when it matters most.
Every step of this process will be applied to every Navanos timepiece that follows the Ravaro.
The standard is set. It does not move.
