Sapphire Crystal Watch Mirror with AR Blue Coating The sapphire crystal watch mirror is exceptionally tough and can withstand significant impact without shattering or cracking.It has an anti-reflective coating that helps minimise glare and reflections, improving visibility while maintaining an elegant and luxurious aesthetic. Super Luminous SLN C3 Green & BGW9 Blue Light SLN C3 green and BGW9 Blue luminous markers and hands offer outstanding visibility in dark environments, which is distinct and visually appealing.It quickly absorbs and stores light energy to provide long-lasting glow, ensuring that the watch remains readable in low-light environments for hours. Screw-down Crown The main purpose of the screw-down crown is to prevent water from entering the case, which helps increase the water resistance of the watch.By tightly screwing down the crown, it creates a watertight seal, protecting the internal components from moisture and water pressure. Wear Comfortably With a green strap in the same color as the dial, it is lightweight and soft, with excellent breathability for all-day wear.There are multiple adjustment holes to fit most wrist sizes, and the extra length of the strap can be tucked back into the retaining loops to prevent it from flapping around.
