Advice on authenticity of 78360 bracelet

[Sagee]

I have read so much on here about the various clasp codes and markings on rolex clasps/bracelets/endlinks. But despite all that I've read I still can't come to the conclusion on the authenticity of this 78360 clasp/bracelet with 580 end links. I'm hoping some here can help me determine if it's authentic or not. I have read that there may not be clasp codes on some vintage bracelets, but I'm uncertain if what I have here is one of those or simply not genuine rolex. The links closest to the clasp seem to be different than other 78360 half links that I've come across before. Thanks in advance for any and all help.
