Omega Speedmaster 1564/975 bracelet, found at flea market. Genuine?

Hello all! I have recently purchased this Omega Speedmaster bracelet ref. 1564/975 at a flea market. I don't know if it is a genuine piece, and would very much appreciate your opinions. Stamping layout is different from examples I can find online. STAINLESS STEEL marking is on top, ref. 1564/975 is in the middle, SWISS MADE marking is on the bottom, with the 62 certification stamp on the side rather than above the text. Link codes read GAE. Thank you!
