WaveCatcher Seagrass – 38mm Automatic Surf GMT Watch

The Seaborne WaveCatcher Seagrass is a 38mm automatic surf GMT watch inspired by vintage surfboards and the carefree beach culture of the 1960s and ’70s. Powered by the Seiko TMI NH34 automatic GMT movement, it pairs a laid-back coastal dial with a custom GMT bezel marking famous surf breaks around the world—including Pipeline, Cloudbreak, Maverick’s, Supertubes and Montañita.

The WaveCatcher Story

Most GMT watches are concerned with places like London, Tokyo, Rome or Sydney.

Who cares?

Want to know what time it is at Pipeline in Hawaii? Cloudbreak in Fiji? Maverick’s in California?

Now we're talking.

WaveCatcher was built around a simple idea: wouldn't it be more fun if your GMT watch tracked the places you'd actually rather be?

Maybe you're headed there.

Maybe you've already been.

Or maybe you're sitting at your desk wondering what the morning looks like at Cloudbreak while someone nearby is talking about quarterly projections.

That's okay too.

One glance at the WaveCatcher and you're somewhere else.

Seagrass

The Seagrass dial is the more laid-back side of WaveCatcher.

Its muted, coastal palette takes inspiration from vintage surfboards, weathered beach gear and the natural colors you find where land meets water. It still has plenty of personality, but it doesn't need to shout about it.

Think less tropical resort.

More old surf wagon, sandy feet and one more run before heading home.

Like every WaveCatcher, Seagrass was designed around our love of colorful vintage watches, surf culture and the idea that life is a little better when you don't take everything quite so seriously.

And this isn't just a cool dial wrapped around a generic watch.

WaveCatcher was custom-built from the ground up around a rock-solid automatic GMT movement, with sapphire crystal, sapphire bezel insert, 200 meters of water resistance and a stainless-steel case that's perfectly comfortable getting wet.

Busy in the office and wondering what time it is at Supertubes?

Not a problem.

Out to dinner and looking for an excuse to say, “It's 7:00 AM at Pipeline. I should be doing dawn patrol right now”?

Even better.

You don't have to surf to wear a WaveCatcher.

Feel free to use the lingo anyway.

At your own risk.

We won't judge.

Laid-back, colorful and always searching for the next adventure, WaveCatcher is for anyone who loves the beach, surf culture, vintage style—or simply the idea that somewhere in the world, the waves are probably better than whatever you're doing right now.

Strap it on. Check the tide. Live life on Wave Time.

Frequently Asked Questions

WaveCatcher puts a Seaborne spin on the idea by replacing the usual world-city theme with famous surf breaks around the globe.

So instead of wondering what time it is in London, you can daydream about Pipeline, Cloudbreak, Maverick’s, Supertubes or Montañita.

Much better.

What makes the WaveCatcher a surf watch?

WaveCatcher was designed from the ground up around surf culture and vintage surfboard design.

The dial takes inspiration from the colorful boards and laid-back style of the 1960s and ’70s, while the GMT bezel highlights famous surf breaks from around the world.

Just make sure the crown is properly secured before getting wet.

What size is the WaveCatcher Seagrass?

Those proportions give it a wearable vintage feel while still accommodating a mechanical automatic GMT movement.

What is the Seagrass colorway?

Seagrass is the more understated member of the WaveCatcher collection, pairing a muted coastal palette with the vintage surfboard-inspired styling shared across the line.

It's colorful without being loud—more weathered beach shack than tropical cocktail.

Do I have to be a surfer to wear a WaveCatcher?

Absolutely not.

If you surf, great.

If your closest connection to Pipeline is checking the time there during a meeting, that works too.

WaveCatcher is for anyone who loves the beach, vintage surf culture, colorful watches and the idea that somewhere in the world, the waves are probably better than whatever you're doing right now.
