Sternglas Naos Pro S02-NP Men's Automatic Watch • Double-Domed Sapphire Crystal • Miyota 9015 Automatic Movement

The Sternglas Naos Pro Automatic is the refined evolution of a true classic from Hamburg-based watchmaker Sternglas. With a slim 38 mm case in 316L stainless steel measuring just 9 mm in height (excluding crystal), the Naos Pro sets new standards in wearing comfort – the case is approximately 25% thinner than its predecessor. The double-domed sapphire crystal with anti-reflective coating protects the dial on both the front and rear, while the transparent exhibition caseback offers a view of the finished automatic movement.

At the heart of the watch beats the proven Miyota 9015 automatic movement, running at 28,800 vibrations per hour with a power reserve of 42 hours. The calibre features hand-winding and a hacking seconds function, enabling precise time-setting to the second. The date display at 6 o'clock is elegantly framed and integrates seamlessly into the clean Bauhaus-inspired dial. Luminous material on the hands and indices ensures excellent legibility even in low-light conditions. With water resistance to 5 bar, the Naos Pro is perfectly equipped for everyday wear. The watch is available with a 20 mm leather strap or a solid stainless steel bracelet.
