Omega Seamaster Diver 300M Summer Blue Review

Today we have with us the Omega Seamaster Diver 300M Summer Blue Edition (Ref. 210.30.42.20.03.003). This watch is so underrated it’s criminal. The Seamster itself is not really underrated, but this summer blue edition certainly is – you kind of need to handle it to figure out why.

Unique Shade of Blue

I haven’t seen color like this on a dive watch since the ultra cool Mido Decompression Worldtimer, and funny enough the blue on this Seamaster is certainly popping more. The other diver that comes to mind as a comparison is the Rolex Hulk. But again the green on that one is quite brash compared to the soft velvety blue offered on this Seamaster.

The blue on this watch can only be described as a delicatessen version of the natural color gradient found on a beach. The indices, hands, and bezel markings have the lightest blue shade on the watch matching the ultra tropical blue you could compare with the shallowest section of a white sand beach. The dial itself has the rest of the blue spectrum of the sea, from the mid light blue as the water gets deeper, all the way to the deepest section of the ocean, a dark scary black kind of blue.

Oceanic Gradient and Textured Design

There is a texturing at play here that kind of ties the watch together, that I’m not sure I’ll be able to catch on camera but I’ll try. The bezel has that ceramic mirror like texture, but the dial has this really intriguing metallic hue happening, with the center of the dial almost fading to white. The dial is not metal though, it’s also ceramic. The lazer etched waves on the dial play a great roll on this watch, in my opinion suiting this specific summer variation better than the more classic ones.

The rest of the watch is essentially what you find on the classic Seamasters. You’re getting plenty of value here in a very handsome stainless steel sports watch with a really fantastic heritage and Omega quality of build.

High-Performance Specifications

Just to ramble off a few specs for you, you’re getting an anti-magnetic watch, chronometer grade, it has a little date window at 6’oclock, and it has that kind of iconic helium escape valve that the Seamaster is known for. The bezel is of course Unidirectional as opposed to bidirectional for safety concerns while deep sea diving.

Bracelet and Clasp

A little bit of a shortcoming for the entire seamaster range is the bracelet, they still aren’t on par with Rolex perfecton yet. The finish on the bracelet, while acceptable is not outstanding, and it also doesn’t tapper, lending it a bit of a blocky appearance on wrist when viewing it from a side angle. The clasp is also, OK, but again there’s room for improvement. Although technically it has some nice features such as Omega’s patented extendable foldover rack-and-pusher clasp, complete with a diver extension to comfortably accommodate a dive suit.

In-House Movement

Another big standout feature of this watch is the amazing in-house movement. The Omega Co-Axial Master Chronometer calibre 8800, certified by METAS. Not viewable from the back do to the closed caseback, which is fine with me, keeping this watch in line with its tool watch heritage.
