Omega Seamaster Diver 300M Seaweed green dial ref 210.30.42.20.10.001 2025 model — The Watch Business Sydney

Watch of the Week — Omega Seamaster Diver 300M 'Seaweed' 210.30.42.20.10.001 | The Watch Business

If there's one watch that's been on more wrists than almost anything else in the pre-owned market right now, it's the Seamaster Diver 300M — and specifically this green "Seaweed" dial configuration. But finding one in this condition, full set, with a 2025 warranty card? That's a different story.

This one came in covered in protection stickers since new. The owner clearly bought it and barely wore it. It presents in like-new condition — no marks on the case, the green ceramic bezel is perfect, and the wave-pattern dial is as crisp as the day it left the boutique. You're essentially getting a brand new watch without the boutique premium.

Reference 210.30.42.20.10.001 is the stainless steel version on the rubber strap — the one that actually makes sense as a dive watch. 300 metres of water resistance, Co-Axial Master Chronometer movement, METAS certified. Omega backs this one until 2030, so you've got genuine peace of mind for the next five years. The green Liquidmetal bezel insert catches light in a way that photos don't do justice — it shifts from deep forest to almost teal depending on where you're standing.

The Seamaster holds its value well and it's a watch you can actually wear. It doesn't need a polished occasion — it works on a leather-strap day at the office just as well as it does on the weekend. The full set with box, booklets and dated warranty card means resale down the track will be straightforward too. At $7,900 for a like-new 2025 model full set, this one won't stick around.
