can be used as a daily beater, with useful calender function. chrono takes abit of time to get used to, and truth be told, i still get confused. anyway, the platinum is great, can feel the weight, without being excessive. very modern chrono. my only gripe : power reserve is 55 hours, which is great if you wear every other day. i wear mine once a week, and its a pain to keep having to adjust the dates and day.
