Hello Justin, saw your great picture of the Omega Seamaster. I own one as well for many years and had it serviced once. She performs very well and I enjoy the features it incorporates. The 24 Hour (Day - Night ) pointer is especially useful above the Arctic circle to differentiate AM versus PM since the sun may not be seen for month or is shining 24 hours a day. My model has the blue dial with white hands and the 12 hour totalizer has a white background with black numbers. Very clear and easy to read.
From your picture , I can see the wristband is the same as mine. I always purchase the Stainless Steel Bands for my watches. If your band has the Omega (Greek Letter) stamped on the clasp , then it is original. This is an excellent time piece, so wear it in health and enjoy it.
( Sorry I dont have a picture , maybe later ).
