Potential Pepsi Purchase

[Peter.dench]

Hi All,

First post for me as a new member, but info base here seems amazing. Apologies for all the P's in the title!

Ok, so I currently own a green glass Milgauss, and an Omega planet ocean big size.

I have been looking at a vintage GMT Pepsi, and a, very tempted to make a purchase. From a reputable independent jeweller in the UK. 1981 16750 in great condition. I have been to view today. I am comfortable it is not a copy etc. hands in correct order. Matt dial with no WG around the lume. Swiss T <25 at bottom of dial would suggest it's the correct time period. Not opened the back, but appears to be a serial number 7xxxxxx in between the lugs at 12 o'clock. Bracelet shows some signs of stretching, but nothing too bad, printed with 93150 at first link. Small amount of patina on minute hand, and lume matches rest of the dial. The watch comes with original box, but no papers.

I have read a bit about different dials, and associated rarity but am not sure how desirable this version is, any advice welcome.

Tried to understand if the number between the lugs is serial number, but can't quite work it out.

I can purchase for £3500. I am looking to get a better understanding of there are any warning signs here that I am missing, and if value seems fair (I have checked online, but tricky to find direct comparisons)

P.s. The bezel seem a bit stiff to move, but that may just be that I am used to new watches. Jeweller is offering 1 year warrantee included.

Any advice, or opinion very much appreciated.

Thanks!

Pete
