This piece was brought to my attention today and caused me to do a little research...

 

Real. Asia-only model IIRC.

Yup, but honestly it really looks like a fake, the thing I noticed was the signature 3313 spacing, which made me pause and research it. Dial looks sloppy, the furniture looks cheap on the subdials... wierd lume colors...

 

It's real.

 

And here is another rarity, although more obvious that its a real piece.

 

IMO the most worrisome detail/red flag is the inclusion of a date at 4:30. I had the more commonly known model, sans date. So I could see why this variant would give someone pause.

Ironically, this is the watch that confirmed that I cannot own one without a date, lol.

 

The Date at 4:30 is pretty common when Omega used the 3313 movement. You have to admit the dial printing, and Omega subdial hands of that period are pretty poor looking.

 

I meant its inclusion on a Railmaster model, which to my knowledge was a date-less model across the collection.

As for the use of the 3313, yes it is a 4:30 date, but I am pretty sure that movement/AT combo came after the Railmaster rollout, and was more closely associated with the 3303 ATs. Obviously Omega switched it up at some point. Agreed about the dials, teak and subsequent RM dials are much, much nicer.
