Opinions please on this Speedy 145.022-74

Newby here. Please be gentle.

I’ve always wanted a Speedy, and doing research I’ve decided I want a vintage one, not new. I came across this 145.022-74 sold by an Omega Authorized Service Dealer in pretty good shape. I haven’t opened the case to confirm the reference and movement - I’m purely going on the jeweler’s representation. Attached are some photos and I would like your opinions.

I’m not sure if the bracelet is original. The back of the bracelet is different from the front. Is that only on new Speedmasters? It’s too small for my wrist and I would need more links or a replacement.

The dial is stepped, but I have read that the dial should be non-stepped in 1974. As I mentioned, I haven’t asked to see the inside of the case yet to confirm the ref number.

Thanks.

Case has been polished in a way that disfigured the shape of the lugs. Looks bald. I'd pass hard on this one. Bracelet could be a 1450 but end links are 633 so not sure what's going on there. Still a steer clear from me though.

This is all great information. Thanks.
