Can anyone Help me?

Hi everyone, i'm a new member of this beautiful forum, and i have a question about the genuinity of this omega speedmaster pro bracelet that i have bought about one month ago on c24. The bracelet in the pictures look different in two/three point regard the factory bracelet mounted on my speedy.
In particularly there is no 849 engraved on the endlink, the code 70 on the clasp of this while the code 62 on the factory bracelet. Can the experts of this forum help me to know if it's original or not? thanks a lot 😀

Pictures?
EDIT: Also would be a good idea to post in an another sub-forum rather than this one as this is meant for news and member support 👍 you'll get more replies there.
