I've been planning and drooling and dreaming and might be on the cusp of picking up a pre-owned Seamaster Chronograph Regatta, you know, the yellow accent jobbie.

I've seen them with both the lovely wood box and the red leatherette item: is there any way that Omega might have offered them with two box options or does a red box imply not original? Importantly, does red box imply "not quite as it should be"?

Also, its listed as a chronograph and not a chronometer which tells me that it isn't a COSC rated watch: is it the movement? Why so please?

Thanks in advance guys

 

Assuming the box was supplied at time of purchase, red box means pre-Aug 2015, wooden means post, give or take a few months depending on whether the AD chose to comply with the switch over date or chose to deplete their supply of red boxes first.

 

Thank you sir.
