Seeking advice on whether this is a genuine Omega

Hi

Apologies if this is in the wrong section of the forum but I am new and looking to purchase this timepiece and wanted to know if it is genuine or not:

1. OmegaSeamaster PlanetOcean - Calibre 8500 is the make of the timepiece
2. Been told by seller it was purchased in September 2013
3. Bracelet strap identification is 232.30.42.21.01.001
4. Watch serial number is 85694020
5. On the back case it also has S114 - what does that mean?

Thanks in advance for your help.

Can I suggest reposting this in the modern omega subforum

. You will get more attention there.

Thanks guys and reposted here http://omegaforums.net/forums/modern-omega-watches/

Thanks Northernman and that was my advice, any recommended autorised omega outlets in Edinburgh, scotland.

Looks correct to me. The case, the movement, the laser etched serial number in lug & globe marking in case back are legit.
Si14 showing that the movement utilize Silicone (which in periodic table number is 14) for its balance spring.

+1 on that, looks fine.👍
