The SS-1 takes its name from the USS Holland (SS-1), the Navy's first commissioned submarine and the one that started it all. Inspired by the diesel smoke and grease-stained decks of the early fleet, this watch is built with the same grit, durability, and purpose that defined those who served beneath the surface.

Powered by the trusted NH35 Seiko automatic movement and protected by a sapphire crystal, the SS-1 is engineered for dependable performance. Tested in-house to 100 meters of water resistance, it's built for more than the water—it's equally at home in the shop, on the job site, or wherever the mission takes you.

Built with hardened stainless steel and a ceramic bezel, the SS-1 reflects the straightforward reliability that defines the Tin Can Timepieces collection. No gimmicks. No shortcuts. Just proven materials, dependable engineering, and purpose-built performance.

Time-tested. Purpose-built. Nothing extra.
