my wife tried on some PP´s last Saturday. She wanted to try the Twenty-4 (was to "blinky" and quartz was a NoGo - for her), didn´t like all the Aquanauts (especially with stones) and was very sceptical about the Nautilus 5800. After a while she fall in love with it and told me not to by the 5980. Here proposal was 5711/A and 5800. Now I have a problem to solve ;-)
Good luck with your decision.
