On Omega's site they use either "Seamaster 300" or "Diver 300M" for the heritage style versus the modern professional style. But on here and every other forum I see people use the terms "Seamaster", "Seamaster 300", "SMP", "300M", "Diver 300" all to refer to the modern diver. Is there a unique term that everyone would immediately understand to mean the older style specifically? Clearly "Seamaster 300" is too ambiguous. It just makes searching a bit difficult and even when browsing other threads I'm often not sure which watch we're talking about unless pictures are included.

 

It is sometimes referred to as "Seamaster 300 Master Co-Axial" or "Seamaster 300MCA". This comes from the first generation being one of the first watches to receive the fully anti magnetic Master Co-Axial movements (which were short lived and replaced by the Master Chronometer METAS movements)

 

I have the same pet-peeve. The modern one should be referred to as the Seamaster Pro/Professional, or SMP. Adding the 300m (or just 300j is just confusing. Leave the “300” designation for the heritage version.

I have so decreed it. So now there’s no excuse for anyone to make that mistake.

 

Just find some superhero name and name it

 

I find it funny that 'Bond' could technically apply to both models, albeit it would be a bit of a stretch for the MC. I think Omega is calling the 300m the 'Diver' now to try and distinguish the two.

 

Agree! SM300 = the vintage model

 

Ahhh, there it is. "SM300" seems to be the magic combo, when I search for that everything looks to be the vintage model. Thanks!

 

SMP=newest

 

I find it amusing (and sometimes maddening) that people in enthusiast forums tend to create abbreviations for everything as if this proves they are part of the in-crowd and others are not.

If you want to avoid confusion, just say what you mean! If you mean a "vintage-style Seamster 300 Master Coaxial" then type that.

Where do I get off saying that? I'm a technical writer. It's my job to not be misunderstood.

 

Seamaster Diver, Seamaster Professional, SMP 300, Diver 300 all refer to the newer variant. Seamaster 300 is the older heritage model.

Let's start a debate over Submariner No Date...

 

But what about the 1960s Seamaster 300 or the WatchCo modernish variant?

 

I like to short it all to "SM300MC", and hope The Internet will follow me
