Beast to me because I typically play in the 38-39 mm space 😉

Initial impressions:

Next to all the other Seamaster 300 Divers in the case, I could not easily pick out the green one, even though it should have been obvious next to the other dark blue, light blue and black ones. Why? Because in fact it looked Grey in the case! It was only when I handled this particular Omega and put it on my wrist that I was sure I had the correct model, affectionately named “Seaweed.” Under the bright, harsh AD lighting, you can finally see the green tone. Although it is quite subtle. Especially in pics. In real life it is slightly richer. Green enough to differentiate itself from the sea of white, black, silver and blue dials out there. Yet a versatile enough green to know you’re still wearing a green watch, while not screaming, “hey look how green my watch is!” Looking closer at the dial and bezel, we see a very attractive military like hue and don’t forget the cool waves! The finish of both are shiny ceramic. But still retain an overall subdued look because we don’t have a brushed or sun burst dial here. The classic SM skeleton hands retain the charm of the mid 90’s and I can’t think of a better set to go with this particular piece.

I walked into the AD having no doubt that 42 mm would be a stretch for my 7 inch wrist. At 42 x 13.5 x 50 mm. It is, well, quite a beast to me. BUT! On the wrist, surprisingly, there was no lug overhang and the lug to lug actually wears similar to the OG 41 mm SeaMaster Diver 300 from the 90’s. A pleasant surprise. Although I’d bet the farm this one is about 2 mm thicker than that OG. However, it’s all quite well proportioned because you have a 42 mm case size. Omega did a phenomenal job here making a larger size watch more wearable for medium sized wrists. Actually quite a thoughtful, impressive and well executed design element .

Better with no He Escape valve and a tapering bracelet for a desk diver like me? Yes, definitely. But the rest of the watch is so good. Not a deal breaker. I also have a preference for dive watches with no crown guards. However this is not blocky or bulky and blends in nicely with the case and bezel shape. So not a bad thing. The bracelet is rock solid and all business. I like the classic SeaMaster link patterns which is a fresh breath with all the other oyster styles out there. Milled clasp, easy, secure twin trigger release and micro adjustment on the fly. Again, kudos to Omega here

This is Omegas green take on a classic diver. It’s not in your face loud, but rather quite tastefully done. They’ve balanced the entire package nicely, and again, I give them credit for making a very attractive offering here. Add the value of pre-owned pricing and I’m not sure it gets better at that price point. Could this be the green diver to rule them all for me? 😎🌊

Thanks for looking friends!

Key Points from the Discussion

The helium escape valve, often a point of contention for some collectors, is viewed as a 'quirky cool' feature by others, and its presence on the Seamaster Diver 300 doesn't detract from the overall appeal for those who appreciate the watch's character.
The subtle green hue of the 'Seaweed' can appear almost black in certain lighting conditions, making the right illumination crucial for appreciating its true color, a factor that has led some collectors to prefer other green diver options.
While the 'Seaweed' offers a distinct green, some collectors express a preference for other green Omega models, such as specific Planet Ocean references, suggesting a diverse range of aesthetic tastes within the brand's green dial offerings.
The 'Seaweed' green dial's appearance can be highly variable, often looking grey in artificial retail lighting, but is expected to reveal its richer green tones more vibrantly in natural sunlight and outdoor environments.
Despite the appeal of the 'Seaweed' variant, some collectors would personally opt for the non-limited edition, no-date versions of the Seamaster Diver 300, indicating a preference for simpler, more classic configurations.

Thanks for the in-dpeth hands-on review!

Even if it looks nice, now that they make non-limited edition no-date variants, I would personally rather choose one of those. Just my feeling, of course. Best, Emmanuel

Tony, I fell in love with the diver style, color and bracelet

And have owned several Aqua Terra and SeaMasters in the past, so am familiar with the brand. I also realize it’s not going to be for everyone. Can you please elaborate on what you don’t like?

I actually owned an original one that came out for 007 but something about the helium valve crown just didn’t look right.

I had a Diver 300 many years ago — I was not a fan of the helium valve as well and I sold or traded the watch.
