Omega has 3 rubber straps (red, white, blue), coming out for the Seamaster in advance of the Olympic games in France.
The kick is, the straps come with a quick release connector already attached to them, so you don't need spring bars to attach to the frame.
They are not sure of they are deployant or tang but the boutique is going to call me when they get a red one in (for the white dial Seamaster). Price is around 300$ USD
A view of the quick release (and I guess you could order a stainless steel bracelet with the quick release as well):
