I've had 2-3 Swatches over the years, and was looking for a replacement for sports/sauna/etc activity.  The Once Again is a typical "clean" Swatch design, but I find the day/date to be very distracting when glancing at the watch-it seems that the minute hand is stuck at approximately :15 every time I look at it!

Pros:
Simple design
Comfortable

Cons:
Day/Date makes it look like minute hand is stuck at :15
Face is a bit small for a typical man's wrist
Band could be bigger
Band can't be replaced (from what I can see)
