    Don't worry you're not wrong: Rolex's SCOC is more stringent than COSC standards (which is not affiliated with any one brand). High end manufactures are increasingly coming up with their own standards: Omega helped to create the Master Chronometer certification, Patek has their PP seal, etc.

    update: i let the watch run down to 0 and then tried again, leaving it in different positions over night. flat, it now runs 8 sec/day slow, resting it on the dial down it runs 2 sec/fast day. Much better...
