Not to be rude but the search function is your friend. I have posted several pics with comparisons which i no longer have on my desktop. This is a frequent topic but a good question. I own both and 289 maybe worn my 270 twice for reasons of preference to the 233 stated in previous threads. Some 233 i s had issues when the power reserve was low but was pretty rare. The 8 day manual wind mvnt is perfection and makes sense the 10 day auto what is the point?
