Collection: Crystals for Citizen ECO-Drive series

Ensure your light-powered timepiece remains crystal clear with our premium replacement crystals for the Citizen Eco-Drive series. Because Eco-Drive technology relies on light penetration through the dial to charge the movement, maintaining a scratch-free surface is vital for both aesthetics and charging efficiency.

We offer high-performance Sapphire Crystal upgrades that provide 3x the scratch resistance of standard mineral glass, ensuring your "watch that never needs a battery" remains as pristine as the day you bought it.

Crystal Options for Eco-Drive Models:

• Premium Sapphire Upgrades: High-clarity synthetic sapphire with a Mohs hardness of 9. Virtually impossible to scratch under normal daily use.

• Anti-Reflective (AR) Coating: Specialized underside coatings to reduce glare, making the dial easier to read in bright sunlight and improving light absorption for the solar cells.

• Flat & Domed Profiles: Choose a flat crystal for a sleek, modern look or a domed crystal for a classic, magnified aesthetic.

• Tough Series Glass: Extra-thick replacement crystals designed for the Promaster Tough and Super Titanium Eco-Drive collections.

Compatible Collections: Our crystals are precision-cut for the most popular Eco-Drive families, including the Stiletto (Ultra-thin), World Chronograph, Brycen, Calendrier, and the Promaster Solar diver series.

Technical Note on Light Charging: Our sapphire crystals are laboratory-tested to ensure maximum light transmission. Upgrading to sapphire will not interfere with your watch's ability to charge via solar or ambient light. For assistance with case reference numbers, contact our experts at info@wrwatches.com.
