Sternglas Lumatik S02-LM17 Men's • Miyota 8315 Automatic Movement • Sapphire Crystal with Anti-Reflective Coating

The Sternglas Lumatik S02-LM17 is a bold men's automatic watch that combines sporty luminous dial aesthetics with artisanal precision. The light blue satin-finish dial features white and orange Luminova indices alongside orange hands, delivering striking accents that remain clearly legible even in the dark. The polished 316L stainless steel case, measuring 38 mm in diameter and 12 mm in height, sits comfortably on the wrist and impresses with its timeless proportions.

At its heart beats the proven Miyota 8315 automatic movement, operating at 21,600 half-oscillations per hour with a daily accuracy of −20/+40 seconds and a maximum power reserve of 60 hours. A date window at 6 o'clock, hacking seconds, and manual winding round out the feature set. A double-domed sapphire crystal with double anti-reflective coating protects the dial, while the screwed sapphire exhibition caseback offers a view of the movement. Water resistance is rated at 5 ATM.
