Glashütte Original SeaQ Chronograph 'Silver Screen' Debuts With ISO 6425 Certification
Glashütte Original Expands SeaQ Collection With ISO 6425-Certified Chronograph
Glashütte Original has added a striking new member to its SeaQ dive watch family with the introduction of the SeaQ Chronograph "Silver Screen." Unveiled in late 2024, this luxury diver represents a convergence of high-end German watchmaking precision and rigorous international diving standards, carrying official ISO 6425 and DIN 8306 certification.
What Makes ISO 6425 Certification Significant?
The ISO 6425 standard, established by the International Organization for Standardization, defines the minimum requirements for watches designated as "diver's watches." Unlike casual water-resistance ratings, ISO 6425 certification involves a battery of stringent tests that simulate extreme underwater conditions.
According to Glashütte Original, the SeaQ Chronograph undergoes comprehensive testing including:
- Water resistance testing at 125% of the rated depth (375 meters for a 300m-rated watch)
- Thermal shock resistance by alternating between 40°C and 5°C water
- Condensation testing to detect any moisture ingress
- Pressure resistance tests at the manufacturer's overpressure value
- Bezel function testing including timing capability verification
- Luminous legibility tests in darkness conditions
The SeaQ Chronograph's 300-meter water resistance rating places it firmly in the professional dive watch category, alongside icons like the Rolex Submariner and Omega Seamaster.
Silver Screen Design: Where Cinema Meets Horology
The "Silver Screen" name references the specific type of projection screens used in cinema, which featured thin coats of silver paint to reduce light dispersion and increase contrast. Glashütte Original has replicated this effect on the dial using galvanic silver, creating a surface that may appear white but possesses distinctive depth and shimmer.
The watch features a 43.2mm stainless steel case measuring 16.95mm thick with a 51.6mm lug-to-lug distance. The unidirectional rotating bezel incorporates a black ceramic insert with white markings, complementing the monochromatic theme. The hands and indices are filled with Super-LumiNova for underwater legibility—a critical ISO 6425 requirement.

The In-House Caliber 37-23
Through the sapphire caseback, the in-house Caliber 37-23 flyback chronograph movement is visible. This automatic caliber features Glashütte stripes on the three-quarter plate, beveled and polished edges, and a skeletonized rotor with the double-G logo in gold. The silicon balance spring provides enhanced accuracy and resistance to magnetic fields—a feature increasingly common in modern high-end dive watches.
The flyback function allows instant resetting and restarting of the chronograph with a single push, a practical feature for timing successive diving intervals.
Strap and Bracelet Options
The "Silver Screen" is available on three strap options: a perforated black rubber strap with steel folding clasp ($14,700), a steel three-link bracelet, or an orange textile strap. The rubber strap version shown in hands-on images features a textured surface designed for grip during water activities.
FAQ
Q: What is the difference between ISO 6425 and simple water resistance ratings?
A: ISO 6425 is a comprehensive testing standard that includes thermal shock, condensation, overpressure, and legibility tests. A simple water resistance rating (e.g., "200m") may only indicate static pressure testing without the additional durability and safety requirements.
Q: How does the SeaQ Chronograph compare to other ISO 6425-certified luxury dive chronographs?
A: The SeaQ Chronograph competes with watches like the Omega Seamaster Diver 300M Chronograph and the Tudor Pelagos. Its German finishing, silicon balance spring, and flyback functionality distinguish it in the market.
Q: Is the flyback chronograph useful for recreational diving?
A: While not essential for recreational diving, the flyback function is valuable for technical divers who need to time multiple decompression stops or bottom times in succession.
According to aBlogtoWatch, the Glashütte Original SeaQ Chronograph "Silver Screen" is priced at $14,700 on rubber strap and is available through authorized retailers.
