About the Naos

The Naos is the classic model in the Sternglas lineup: clean Bauhaus lines, high-quality craftsmanship, designed in Hamburg.

It’s perfect for everything from the office to leisure and fits under any shirt sleeve. Just like in the Bauhaus, form follows function.

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.

Miyota 6P20 with moon phase

The Miyota 6P20 quartz movement is housed behind the screw-down stainless steel case back.

The movement controls the moon phase at 6 o’clock as well as the calendar displays for the date and day of the week. The accuracy is -20/+20 seconds per month, with a battery life of up to three years.

As a result, the Naos Moon Phase offers a precise moon phase display as well as a practical calendar function for everyday use.

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.

    Questions about the Naos

    Can I order my watch with a different strap?

    Our watches are available in carefully selected watch-and-strap combinations.
    Want to switch up your look? Simply add an extra strap of your choice when purchasing a watch and get 30% off the additional strap at checkout.

    How long does the battery last?

    The batteries we use typically last between 2-5 years. We recommend having a jeweler or watchmaker perform a battery replacement.

    Did you know that ...

    …the lunar cycle lasts about 29.5 days?
    From new moon to full moon and back to new moon, this exact period passes. For centuries, calendars, tides, and even agricultural rhythms have been guided by this natural cycle.

    The moon phase display of the Naos Moonphase makes this rhythm visible and brings a piece of celestial mechanics onto the dial.
