Glashütte Original SeaQ Chronograph "Silver Screen": Dual ISO 6425 & DIN 8306 Certified
Glashütte Original SeaQ Chronograph "Silver Screen": Dual ISO 6425 and DIN 8306 Certified
Glashütte Original has added a striking new variant to its SeaQ dive watch collection: the SeaQ Chronograph "Silver Screen." Named after the silver-coated projection screens used in early cinema, this timepiece stands out as one of the few luxury dive chronographs certified to both ISO 6425 and DIN 8306 standards.
According to aBlogtoWatch, the watch features a galvanic silver dial with high-contrast black subdials and hands — achieving the cinematic aesthetic its name suggests.
Understanding ISO 6425 vs DIN 8306
Most dive watch enthusiasts are familiar with ISO 6425, but DIN 8306 is a German national standard that often predates and in some cases exceeds the international requirements. Here's how the SeaQ Chronograph measures up against both:
| Standard | Key Requirements | SeaQ Compliance |
|---|---|---|
| ISO 6425 | International dive watch standard | Certified |
| DIN 8306 | German dive watch standard | Certified |
| Water resistance | ISO 6425: 100m minimum | 300m |
| Bezel | Unidirectional timing bezel | Ceramic insert, 60-minute scale |
Germany has a long tradition of rigorous watchmaking standards, and DIN 8306 reflects this heritage. By meeting both certifications, the SeaQ Chronograph positions itself as a dive watch tested against the world's most demanding specifications.
The "Silver Screen" Aesthetic
The dial of the SeaQ Chronograph "Silver Screen" uses galvanic silver rather than traditional white, creating a subtly different visual effect. This approach mirrors the silver-painted projection screens of early cinema, which used thin coats of silver to reduce light dispersion and increase contrast.
The high-contrast scheme continues with:
- Two black subdial rings at 3 o'clock (30-minute counter) and 9 o'clock (small seconds)
- Black Panorama date window — a Glashütte Original signature
- Black-outlined hands and indexes filled with Super-LumiNova
The subdials feature a "vinyl" decorative finish achieved through lathe-cutting, adding textural depth to the monochrome palette. The box-shaped sapphire crystal creates interesting distortions at certain angles, though this is more of a visual quirk than a functional concern.
Movement: In-House Caliber 37-23
Powering the SeaQ Chronograph is Glashütte Original's in-house Caliber 37-23, a flyback chronograph automatic movement. Key specifications include:
- Power reserve: 70 hours
- Frequency: 28,800 vph (4 Hz)
- Jewels: Not specified
- Balance spring: Silicon (antimagnetic)
- Shock protection: Yes
The movement features traditional Glashütte finishing: three-quarter plate with Glashütte stripes, beveled and polished edges, polished and blued screws, and a skeletonized rotor with the double-G logo in gold. According to Glashütte Original, the silicon balance spring provides enhanced antimagnetic properties — an increasingly important feature as daily life exposes watches to more magnetic fields from electronics and modern infrastructure.
Case Construction and Dimensions
The "Silver Screen" is housed in a substantial steel case with the following measurements:
- Diameter: 43.2mm
- Thickness: 16.95mm
- Lug-to-lug: 51.6mm
While these dimensions place it firmly in the larger dive watch category, the curved lugs help the case conform to the wrist. The majority of the steel surface features a brushed finish, with polished edges providing visual accents. The unidirectional rotating bezel is fitted with a black ceramic insert with white markings, maintaining the monochrome theme.
A sapphire display caseback reveals the decorated movement, though the "Made in Germany" text on the dial serves as a reminder of the watch's Glashütte origins.
Strap and Bracelet Options
The SeaQ Chronograph "Silver Screen" is available with multiple attachment options:
- Black rubber strap with perforated texture and steel folding clasp ($14,700 USD)
- Steel three-link bracelet
- Orange textile strap
The rubber strap features a textured, perforated design that's both visually distinctive and practical for water activities. The steel folding clasp includes the Glashütte Original logo.
Historical Context
The SeaQ collection, introduced approximately five years ago, draws inspiration from the 1969 Spezimatic Type RP TS 200 watch made during the Glashütter Uhrenbetriebe (GUB) era. This heritage connection adds authenticity to the collection's dive watch credentials, grounding the modern iterations in actual historical diving watch production.
Frequently Asked Questions
What is the difference between ISO 6425 and DIN 8306 certification?
ISO 6425 is the international standard for dive watches, while DIN 8306 is a German national standard. DIN 8306 was developed independently and in some areas exceeds ISO requirements. Watches certified to both standards have undergone the most rigorous testing available for dive watches.
Why does Glashütte Original use a silicon balance spring?
Silicon balance springs are antimagnetic, lightweight, and highly resistant to temperature changes. As modern life exposes watches to increasing magnetic fields from smartphones, laptops, and other electronics, silicon components help maintain accuracy in everyday conditions.
Is the SeaQ Chronograph suitable for professional diving?
Yes. With 300m water resistance and dual ISO 6425/DIN 8306 certification, the SeaQ Chronograph meets the requirements for professional diving applications. The flyback chronograph function adds timing versatility for decompression stops and other dive-related timing needs.
