Hi all, I'm looking at this SM300 166.024 "Big Triangle" and everything (to me) checks out as appropriate – the aging of the dial, case, and hands; the color and consistency of the lume; all the fonts on the dial and bezel. However, the inside of the caseback has a layout of text unlike any other legitimate example I have seen (and it doesn't list the correct model reference number). Also, my eyes may be playing a trick on me, but the sea monster's proportions on the back look a little bit off. I used Arne's vintage SM300 guide as a reference for the fake-busting along with my own knowledge. Thank you in advance as always; you guys are awesome. Happy (much needed) Friday! Jeff Edit: I should add one other potential red flag... This movement appears to date to '68 with the 27m serial. According the Arne's blog post, "The baton hands were used on early models, usually dating from 1962-1964 (...) It is highly likely that Omega used baton hands after 1965, but I would be suspicious of pieces with baton hands dating from 1968 and 1969."
