This is an authentic Omega Planet Ocean RUZ005702 blue rubber watch strap, featuring a waterproof blue alligator leather top side and a comfortable blue rubber underside. This is an authentic Omega watch strap that was removed from an Omega Planet Ocean 600m with the Cal. 8900 movement.
I have provided detailed photos of the strap from every angle—please refer to them for a closer look.
