·Hello, does anybody know if it is possible for an authentic Seamaster ref. 135.011 to have a 611 caliber and no "Seamaster" or "Seamaster 600" inscription on the dial? It isn't listed on the vintage omega database. I've found one for a good price, and i think that it is quite beautiful, but I'm a little worried that it's a so-called frankenwatch. The pictures are of the watch in question. Thanks in advance.
