hi guys,

I am in the process of completing a sale for a limited edition U-Boat Silver edition. it was advertised as a 53mm , but I think it is a 45mm?, I noticed that the plastic certificate in the picture does not have the 016 serial number, ( but it is written on the back of the card)

I feel like this is a red flag, would the serial number on the front not be 016, as that is the serial number for the limited edition piece ?

and should it not say a925 as model for the solid silver version ?

I just want to make sure that this watch I am buying is the real deal and not a fake..

thanks for your help guys.
