Hey guys. Chasing something so selling. This one is the big one at 55mm. I don't see a mark on it anywhere except a swirl on the clasp. It WILL come with the original strap but will have the heavy duty Super Engineer bracelet on it. Packaged securely but not box to save on shipping. USPS insured. $199 with the bracelet and OEM strap. Payhpal is fine. We can chat if you want to do something else. Thanks
