not sure, i stopped in because I saw the store and started drooling, but had only about 5 min, and the woman spent most of that not knowing how to use her reference to tell me something about the 45.5 PO I was looking at. Might try to get back there Sunday and figure this out. The Omega website doesn't have it, and when I called, the guy at the store had no clue. They really have a brain trust at this new place.
