Except for the AP ROO, every replica rubber strap I have in my collection did spontaneously break at some point in time. You name the brand: Porsche, Oris, B&R, Bvlgari, Hublot, Corum, Baume et Mercier, and IWC. What all these rubber straps had in common was some kind of embossed details on it, like brand names, logos, decorative holes, anti-sweat patterns, etc. The AT2009 rubber strap has a lot of these details on its interior surface (the diamond-like pattern), probably meant as an anti-sweat feature.
Both my AT2009 (chrono and auto) had to be modified and adapted to receive NATO straps because their rubber straps failed. I wonder if this new release also is doomed to become a paperweitght in the near future because of a poor quality rubber.
