Watch Cases

The watch case defines more than just looks — it protects the heart of your timepiece. From brushed stainless diver cases to elegant dress shells, every detail matters. Whether you’re upgrading with transparent backs, polishing a vintage case gasket, or experimenting with bezels & inserts, our cases fit Seiko NH, ETA, Miyota, and ST movements perfectly. Modders love mixing sapphire domes and polished lugs for that “factory-fresh” yet custom feel.

Complete your setup with sapphire crystals for durability and rubber straps for versatility. Learn more from our blog How to Choose the Right Watch Case or explore custom engraving options. If you’re into waterproof builds, use case openers and repair kits to reseal your project perfectly. From rugged diver bodies to minimal field designs, your watch’s style starts right here — with the perfect case.
