The 289 is really nice, if you like the rose gold, I say go for it.
I went with the 270 beacuse I was looking for an automatic watch with long power reserve, but nowhere as big or as heavy as the IWC Big Pilot. The PAM 270 is perfect. I love the "9" and the AM/PM indicator is more precise and practical than the 233/289. My J series came two weeks ago, after 6+ months on my US AD wait list. Good luck in your search.
