All of our watch batteries can be found at any electronic store, as well as most watch repair or jewelry shops. Any watch repair shop or Jeweler should be able to assist you with the battery replacement. We don't suggest replacing the battery, as it requires some special tools and you could damage the watch.
All of our sunglasses are UV 400 protected, which blocks all light rays with wavelengths up to 400 nanometers. (This covers all of UVA and UVB rays.)
Polarized sunglasses are specialized eyewear designed to reduce glare from surfaces such as water, snow, and glass. Glare distorts the true color of objects and makes them harder to distinguish. The main difference is that polarized lenses are designed specifically to block the glare from reflected light while non-polarized lenses only block intense light.

Is there a warranty?

GRVITI warrants that our sunglasses are free from manufacturing defects (in material or workmanship) for a period of 30 days from the date of purchase. This does not cover scratches on lenses, damages caused by accident, abuse, neglect, improper use or storage of the product, unauthorized modifications, or normal wear and tear.
