Omega Seamaster AT 2504.70 Mother of Pearl: Advice

Hello awesome OF people,

I am lookign in buying an AT 2504.70 at 36mm - I have a very skinny wrist and everythig above 37-38mm and/or lug-to-lug above 46mm is too large for me.

Now this dealer sells only the watch, no papers whatsoever. The reviews are good and it is a commercial dealer and no private person. The images show in my opinion an honest (signs of use) and original watch but given the immense expertise of this forum, it woul dbe great if I get a second opinion. Anything to take care about?

Thank you so much!

Hi and welcome at OF - you can ask the dealer ,to send you the "certificate" he will include concerning the originality of his watches. And then: read this carefully.

Nice watch btw.

Thank you! I asked this already, they do not provide any certificate, they 'guarantee' though their watches are original. Whatever gravity this has. The reviews of the shop are good and I have a 2 week return policy, if e.g., the watch is fake. However, I am not sure what can I really achieve in two weeks. Authentification through Omega takes long and costs much. Omega dealers might also not provide such 'authentifications'.

I just sent you a pm with the Info, thanks a lot!
