You don’t need a yacht to love the ocean.

You don’t even need an ocean. A lake counts. A river. A puddle…probably.

We design watches for the water-obsessed — the dreamers, the roamers, the salty-aired romantics — people who can’t look at a horizon without wondering what’s past it.

Vintage vibes. Modern reliability. No ridiculous luxury markup.

And because we actually care about the ocean — not just the aesthetic — we give 5% of profits to nonprofits that protect coastal waters and the families who work them.

Watches for people with saltwater souls.

A Note From the Founders

Seaborne started as a simple idea:
make watches that feel like salt air, adventure, and color — without the luxury nonsense.

Brian grew up on the New England coast and has always been drawn to the water — docks, dunes, fog horns, the smell of the march at low tide (if you know, you know!).  He also had a passion vintage tool watches that were built for real use, not for glass cases. Eventually he stopped hunting for the perfect watch and decided to build it.

Amanda grew up here too — but her heartbeat has always been for community and for the people that create all the things we love. She’s spent years supporting nonprofits, local makers, and community organizations. To her, the coast isn’t a postcard — it’s a network of hardworking families, small businesses, and neighbors who show up for each other.  

Together, we built Seaborne with two promises:

1. Make colorful, adventurous watches that actually get worn.

2. Give back to the coastal communities that inspire them.

5% of our profits go directly to organizations that protect small-boat fishing families, sustainable shellfishing, and working waterfronts.

We believe business should do more than generate revenue — it should generate good.

Thanks for being part of this crew.
