Real or fake?

[cheechuen]

Hi guys,

I just got this watch as a heirloom. I have seen its serial number and model number laser on 6 and 12 o clock lug quite neat. Hopefully the watch is real?

Could I know if it's fake or real bracelet? It's a 16018. It has been 20+ years and it's still shiny gold, ticking etc. I plan to take it for RSC if it is real n dont want awkward situation.

Please see pics

Thanks
