CALX Watches:
Located in the United States, CALX creates custom watches that are all about quality and affordability. We carefully modify Seiko movements with premium aftermarket parts. At CALX, we bring the designs of luxury watches to a wider audience without resorting to counterfeit products.

DEDICATION TO QUALITY
Our watch cases are crafted from 316L stainless steel, a durable and corrosion resistant material. Inside of our cases is the renowned Seiko automatic movement. The Seiko NH series movement is known for its reliability and precision. The crystal that products the watch face is made from sapphire. Sapphire crystal is the gold standard for modern watch crystals.

ACCURATE
Our Seiko Mods are driven by the NH series automatic movement. This movement is renowned for its precision and reliability. It's designed to keep time with remarkable accuracy, gaining or losing just 3-5 seconds per day.

LEGITIMATE & GENUINE
Our timepieces are not replicas. Each CALX watch houses a genuine Seiko movement to create unique watches inspired by top designs. We are not affiliated with the Seiko brand in any way.
