I'm sorry, the planet ocean I bought came with the stainless steel bracelet. I am looking at buying an omega rubber strap & don't know how to determine which size length I need. Thanks!
I think if your wrist is anywhere from about 6.5 inches to 8.5 inches you should be fine with the regular sized Omega rubber strap. It might be worth looking at the Isofrane rubber too, they're very nice and somewhat cheaper.
