Hello I have a Omega Speedmaster Moon Watch Model # 311.30.42.30.01.005 arriving by the end of next week I have been reading up on replacing the clasp currently on the bracelet with one that has the sliding micro adjustments. I came across the following that has part numbers on it. i wanted to make sure that these items will fit my bracelet. i am not sure of the bracelet number but it is the factory OEM one from the 311.30.42.30.01.005 I am sure the prices have changed but can a Omega AD get these parts? the nearest OB is the next state from me. Thanks \
