Gemstones & Pearls
Our gemstones are responsibly sourced, including our natural and lab-grown options. Our gems primarily originate from Brazil, with the exception of some that have origins in Uruguay, Russia, or India. We also use natural freshwater pearls that come in a variety of shapes and sizes and originate from China.
Watch Materials
Discover Ptera quartz watches, crafted with high-quality 316L stainless steel. Known for its durability and strength, stainless steel is the preferred material for crafting watches. Our watches feature 316L stainless steel, which is a grade of stainless steel that is composed of 10.5% chromium, making it resistant to corrosion and providing a metallic finish. Additionally, it contains only 0.03% carbon, making it an ideal choice for high-temperature and corrosive environments.
PVD Plating. Our watches are coated with Physical Vapor Deposition (PVD) to achieve a gold-tone, rose gold-tone, or silver-tone finish. PVD is a vacuum coating process that utilizes a titanium nitride to produce a brilliant, scratch-resistant coating that is highly durable and long-lasting.
Water-Resistant. With a water resistance rating of 3-5 ATM, our watches are splash-proof and can withstand rain and water splashes. However, they are not recommended for full water submersion.
