Any idea whether this looks authentic?

 

Notice the markers at the outer bezel at 1,2,4,5,7,8,10,11 is flat rather than pointed compared to the picture below so which one is the authentic one

 

Ueno San is usually a reliable guy. Here's something that may help

I believe both to be authentic.

 

I'm with Gavin - both look fine to me.

 

Thanks Gavin and ulackfocus but I havent seen anything out there with the flat marker.....all of them were like what mathew bain has pointed markers.... do you have any pictures or catalogues that show flat markers?? And how come there are deviations like that?

Thank you v much

 

In fact the one from mathew bain looks more like a relume than the one i posted... this legend diver is made out of radium?

 

No, stainless steel.
