Our website and payments platform is powered by Shopify, which complies with all six PCI standard categories, making it among the most secure payment platforms on the web.

Despite the name, in reality both of our dials are premium and have identical quality in terms of finishing, lume, and cost. Both dials are constructed of the same high-quality copper.

The only difference is in the face of the dial itself. The Premium option includes a printed logo, and is designed as an homage to the GMT-Master dial. The Standard dial is more understated and minimalist in terms of the amount of text on the face, and includes a metal logo instead of a printed logo.

The Standard dial the only option we carried when our website launched. When we began offering the Premium dial, that moniker was chosen simply as a way to differentiate the watch.
