Glashütte Original SeaQ Chronograph Silver Screen Dual-Certified to ISO 6425 and DIN 8306

Glashütte Original has expanded its SeaQ dive watch collection with the SeaQ Chronograph "Silver Screen," a timepiece that pairs the brand's renowned dial-making expertise with dual certification to both ISO 6425 and DIN 8306 dive watch standards. The watch brings a flyback chronograph complication to the German luxury brand's professional diving lineup.

Dual ISO 6425 and DIN 8306 Certification

According to aBlogtoWatch, the SeaQ Chronograph is officially certified as a diver's watch according to both ISO 6425 and DIN 8306 standards. While ISO 6425 is the international benchmark for dive watches, DIN 8306 is the German industrial standard that predates ISO 6425 and includes additional requirements specific to German manufacturing practices. Achieving dual certification means the watch has undergone two separate, rigorous testing protocols.

This dual-certification approach is uncommon even among luxury dive watch manufacturers and reflects Glashütte Original's commitment to meeting the highest professional standards.

Specifications Overview

Movement and Finishing

The SeaQ Chronograph is powered by Glashütte Original's in-house Caliber 37-23, a flyback chronograph automatic movement. According to aBlogtoWatch, the movement features a silicon balance spring, a shock-resistant oscillation system, and all the brand's signature decorative touches including Glashütte stripes on the three-quarter plate, beveled and polished edges, polished and blued screws, and a skeletonized rotor with the double-G logo in gold.

The "Made in Germany" designation is engraved on both the dial and the movement itself, reinforcing the watch's origin at the Glashütte manufacture.

The Silver Screen Dial

The dial of the "Silver Screen" is crafted from galvanic silver, creating a high-contrast palette when paired with black subdial rings, a black Panorama date window, and black-outlined hands and indices filled with Super-LumiNova. The two subdial registers—a 30-minute counter at 3 o'clock and small seconds at 9 o'clock—feature lathe-cut surfaces with a decorative "vinyl" finish.

According to aBlogtoWatch, the box-shaped sapphire crystal creates dramatic visual distortions of the subdials at certain angles, an effect that the hands-on review specifically highlighted as notable.

Pricing

The SeaQ Chronograph "Silver Screen" on a black rubber strap with a folding clasp (ref. 1-37-23-03-80-33) is priced at $14,700 USD. The pin buckle version (ref. 1-37-23-03-80-06) is available at $14,400 USD.

Frequently Asked Questions

What is the difference between ISO 6425 and DIN 8306?

ISO 6425 is the international standard for dive watches, while DIN 8306 is the German industrial standard. DIN 8306 was developed earlier and includes some requirements specific to German watchmaking traditions. Achieving both certifications means the watch meets the strictest combined requirements.

Is the SeaQ Chronograph suitable for professional diving?

Yes. With 300 meters of water resistance and dual ISO 6425/DIN 8306 certification, the SeaQ Chronograph meets all requirements for professional diving use, including thermal shock resistance, magnetic resistance, and legibility in darkness.

What is a flyback chronograph?

A flyback chronograph allows the user to reset and immediately restart the chronograph with a single push of a button, without first stopping it. This function was originally developed for aviation navigation timing and adds practical value for divers tracking multiple time intervals.
