I have a Speedmaster Professional Reference #3876-50. It is somewhat of a limited piece with a moonphase and date complication. Love the watch. I currently have it on a black leather croc. I would like to get a SS metal bracelet and black rubber strap. I understand the lugs are 20mm. Can anyone tell me the best original Omega SS bracelet to buy? Model number? Additionally, can anyone recommend a rubber strap? I am surprised that RubberB and Everest don't make straps for the Speedmaster. Thank you for your help!
