Collection: Crystal for Citizen Promaster Series

Maximize the durability of your professional tool watch with our premium replacement crystals for the Citizen Promaster Series. Designed for those who push their timepieces to the limit, our crystals provide the clarity and scratch resistance required for deep-sea diving, aviation, and rugged trekking.

Whether you are looking to replace a scratched factory crystal or upgrade to a high-grade Sapphire, our selection is precision-engineered to maintain the ISO-compliant seals of the Promaster line.

Our Promaster Selection Includes:

• Sapphire Crystal Upgrades: The ultimate protection with a Mohs hardness of 9. Ideal for the Promaster Dive (NY0040, BN0150) and Fugu models.

• Anti-Reflective (AR) Coatings: Available in Clear, Blue, or Purple AR to eliminate glare—essential for legibility in high-altitude cockpits or direct sunlight.

• Double-Domed Options: Provides a vintage aesthetic and eliminates dial distortion when viewed at an angle, a favorite for Citizen Eco-Drive enthusiasts.

• Mineral & Hardened Glass: High-quality OEM-style replacements for those looking to restore their Promaster to its original factory specifications.

Supported Series:

• Marine (Diver): NY0040, BN0150 (Eco-Zilla), JP2000 (Aqualand), and BN0190.

• Sky (Pilot): Nighthawk, Skyhawk, and Blue Angels editions.

• Land (Field): Altichron and Promaster Tough series.

Maintaining Water Resistance? Replacing a crystal on an ISO-certified diver requires a fresh gasket and a professional pressure test. We are always expanding our inventory to include Promaster-specific I-gaskets. If you are unsure of your case reference number, reach out to our team at info@wrwatches.com.
