OK. I realize that this is just my personal opinion, but I think the clock is ugly as sin.
The Swiss railway authority should be embarrassed to about their clock.
The Swiss Railway Authority should be paying Apple a hefty sum for using such an ugly icon.
Now, I must admit that I have no use for a clock with no numbers on it. When I buy a new watch which I do about every four or five years, it must have arabic numerals on it. Not hash marks, not Roman Numerals, but Arabic numerals. I want to be able to look at my watch, or clock, and know what time it is. I do not want to have to sit there and count hash marks to figure out what time it is.
Of course, your mileage may vary. If you like the clock, then I am happy for you and I hope you live a long and happy life.
