Seiko Mod Parts & Sapphire Crystals

Browse, Shop, and Mod using the dedicated Crystaltimes USA App!

Crystaltimes USA is a US based eCommerce business that specializes in the design and manufacture of custom Seiko Mod Parts including cases, case backs, movements, stems, crown, bezels, bezel inserts, chapter rings, dials, hand sets, spring bars, click springs, straps, bracelets, and sapphire crystals.

Crystaltimes has coined the phrase "Build Your DREAM MOD" as you can build an entire dive watch from scratch using parts we offer on our website and app.

The purpose of this app is to offer an upgraded mobile shopping experience in addition to our website.

Our goal with this application is to create a streamlined mobile shopping experience for our existing customer base, and for new watch modders as well. We hope you enjoy this app as much as we enjoyed developing it for you.

Happy Modding!
