The Omega Seamaster 300 Master Co-Axial watch is a model that I've been interested to view since it was introduced last year. I've seen and briefly handled the 18k Sedna gold version at my AD, but not until recently did I have a chance to closely look at the stainless steel and titanium versions. I was on vacation on the Royal Caribbean Quantum of the Seas cruise ship destined for the Bahamas where the on-board watch store had a large selection of Omegas. In the display case were virtually all the versions available (combinations of steel, Sedna gold, titanium but not the platinum). The two that interested me the most were the stainless steel with black ceramic bezel and black dial, and the blue version in titanium.

At first glance the two were very similar until I picked up the watches. The steel version had a nice heft to it, and obviously the titanium was extremely light. Not as light as my Breitling Aerospace but it was light for it's size.

The texture of the sandblasted dial blue dial looks great and easy to read. From what I understand the dial is made of ceramic. Logos are printed instead of applied.
The 'vintage' colored super-luminova hour markers has a nice depth to it and it almost looks like a sandwich dial. The rhodium plated hands also have the 'vintage' colored super-luminova applied to it and gives a really nice homage to the original Seamaster 300. The hour markers and broad arrow hour hand have a bluish color in the dark, while the minute hand has a standard greenish color.
The blue polished ceramic bezel ring has a Omega Liquidmetal scale applied to it. Overall I like the diameter of the bezel, not too thin and not too thick either.

The bracelet has a polished central link with brushed finishing on the outer links. It looks very attractive in both versions with the black or blue dial. I prefer deployment buckles and Omega did a nice with this one. The clasp features a rack and pusher extension system for diving, and makes adjustments easier without any tools.

Inside the Seamaster 300 Master Co-Axial is the caliber 8400 made in-house by Omega. It is a COSC certified chronometer, and has anti-magnetic properties taken from the Seamaster Aqua Terra model. The 8400 movement is basically the caliber 8500 without the date (which I prefer on this watch). You can see the co-axial movement with the transparent caseback. The bridges and oscillating weight is decorated with Geneva waves.

At 41mm in diameter the case and bezel is nicely sized for my wrist and to me it looks proportional. The only issue I had personally was with the thickness, I don't know the exact measurements but it was a little too thick for me. The large case lugs also made overhang my small wrist.

It's a tough choice and eventually left both of them back with the store. I'm concerned about the thickness, but really love everything else about this Seamaster. If I had to pick one I think I'd go with the blue titanium version probably because my favorite color is blue. But it comes at a larger price difference between steel and titanium. I'll have to look at it again and see which one will be my next watch.

So what does everyone think about these two Seamasters? I don't know much about vintage so it doesn't really matter to me how it compares to the original model. I like this modern interpretation and seriously consider adding it to my collection. Would you pick the black stainless or the blue titanium version?

Key Points from the Discussion

The titanium version, while lighter than steel, still has significant heft due to the movement and sapphire crystals. The blue dial is particularly striking and distinctive.
The titanium model has a more pronounced appearance and a higher chance of becoming a collectible due to its striking look, technical excellence, and potentially limited production, similar to vintage Speedmaster and Flightmaster references.
The standard steel version appeals to those who appreciate the original Seamaster 300, while the titanium version is for admirers of the modern iteration, especially with its matte blue dial.
The black dial version of the Seamaster 300 Master Co-Axial bears a strong resemblance to the JLC Deep Sea Alarm, which could influence a collector's choice.
The Seamaster 300 Master Co-Axial, particularly the blue titanium, is noted for its 'blocky' profile and height on the wrist, which can be a consideration for some collectors.
The author, ED209, expresses a preference for the blue titanium version but is also considering the JLC Deep Sea Vintage Chronograph as an alternative.

I have few blue dialed ones and it's enough. The Ti case, as you mention is not that lightweight (the movement and the two sapphire glasses sort of neutralize the case weight). About the overall case height, is not a problem to me. About the bracelet, no impressions. I got rid of it by changing to a nice dark brown Cordovan strap. By and large, is a great watch that I'm proud to have. Cheers, Nilo

. . . is that the standard steel version is best suited to a person who reveres the original reference, and titanium for admirers of the current iteration. The appearance and feel of titanium, in conjunction with the matte blue dial . . . [enhanced image - the original was washed out] . . . is remarkably striking. Art

Excellent choice Nilo and thanks for sharing your thoughts on Seamaster. Looks great on your wrist. hmm, a dark brown cordovan strap would look stunning with the black dial and bezel. Regards, ED-209

Thanks Art, I agree the blue is striking. Difficult choice to make, I'm leaning towards the blue titanium. The only comparable watch that I've been contemplating is the JLC Deep Sea Vintage Chronograph. Regards, ED-209

. . . is the more pronounced appearance of the titanium version, even though they're otherwise identical. The black dial might go unnoticed; the blue, probably not. One factor in the titanium model's favor: there's a fair chance it will be a collectible in years to come, kinda like the Speedmaster 125 or Flightmaster ref 145.013, both of which are sought after for their striking appearance and technical excellence compounded by limited production.

the SM300 upon release has interested me..but I have yet to handle one... in the various photos I think the blue is stunning... but as with the DSOM..the watch is tall...its not that I have big issues..but its blocky in profile..I have the 190 and I think its close in thickness but the cushion shape helps... surprised you left it in store..I tend not to venture into dangerous territory... Thanks for the short review...hope all is well
