Key facts

Domed sapphire crystal

Highly scratch-resistant and made for everyday wear: The domed sapphire crystal reliably protects the dial from scratches while adding an elegant sense of depth. The double anti-reflective coating minimizes unwanted reflections and ensures a clear view of the dial, even in challenging lighting conditions.

316L stainless steel, PVD gold, polished

The case is crafted from high-quality 316L stainless steel and finished with a multi-layer gold PVD coating of at least 0.6 µm. Durable titanium-based layers protect the surface against everyday wear, while a fine layer of real gold provides a long-lasting, color-stable finish without the typical tarnishing of other metals.

Screw-down stainless steel case back

The screw-secured caseback made from high-quality 316L stainless steel reliably protects the movement while allowing easy access for battery replacements, maintenance, and repairs. A durable, service-friendly construction designed to keep your STERNGLAS running for years to come.

Quick-change system

So you can wear your watch with confidence, without worrying about every drop of water.

How Does the Hamburg Solar Work?

Beneath the dial of the Hamburg Solar is a discreet solar panel that converts both natural and artificial light into energy. This energy is stored in a rechargeable power cell, replacing the need for a conventional battery. Once fully charged, the watch runs for up to four months, even when kept in the dark.

The stored energy powers the precise Epson AS32 solar quartz movement, delivering reliable timekeeping every day. The Hamburg Solar combines the precision of traditional watchmaking with modern, low maintenance solar technology.

A practical feature: If the seconds hand begins moving in two second intervals, the power reserve is running low. Simply place the watch in the light for about ten minutes, and it will recharge and continue running reliably.

Domed sapphire crystal

Made for everyday wear: Our watches feature highly scratch-resistant sapphire crystal that maintains its appearance even with daily use. The double anti-reflective coating minimizes unwanted reflections and ensures a clear view of the dial, even in challenging lighting conditions. The gently domed shape adds depth and enhances the watch’s premium appearance. This is how we combine durable materials with timeless aesthetics and everyday practicality.

Epson AS32 solar quartz movement

Beneath the dial is the reliable Epson AS32 solar-powered quartz movement, which draws its energy directly from light. The built-in solar panel converts sunlight and artificial light into electricity and stores it in a long-lasting energy storage unit.

Once fully charged, it runs for up to four months. When the energy storage runs low, the second hand moves in two-second intervals, signaling that the watch needs more light. After a short time in the light, it resumes running continuously.

With a rate accuracy of –20/+20 seconds per month and its characteristically smooth operation, the Epson AS32 stands for precision, sustainability, and reliability—a perfect match for Naos’s clear standards.

Bridle Strap Crafted from Waxed Leather

Crafted from premium bridle leather, our Bridle Strap is inspired by a material traditionally used in equestrian equipment, where durability and reliability are essential. Finished with a blend of waxes and oils, the leather develops its distinctive subtle sheen while offering enhanced resistance to moisture and everyday wear.

The soft calf leather lining provides lasting comfort, while the 3 mm strap thickness ensures a balanced combination of stability and elegance. A stainless steel buckle engraved with the STERNGLAS logo completes the design, and quick-release spring bars allow for effortless, tool-free strap changes in seconds.
