·Hello smart Omega people, I'm trying to ascertain the authenticity of a Speedmaster Professional 3570.50 with serial number 483611xx. Every decoder that I check puts it as being manufactured roughly 1998 or later, but the (handwritten) warranty card has the date of May 1997. Could it have been produced in 1997 or likely earlier? I understand that the serial number ranges for Speedmasters can be all over the place, but would appreciate any help with this! Cheers
