Mondaine Clock. The swiss Railway clock that tells time.

Elements I like:

The proportions of the minutes are clearly divided.

the bold markings of the major minutes 5,10,15 etc. are clearly indicated

Good contrast between the hours, minutes and second hands. This helps the user to clearly see what time it is exactly.

elements I wished were there

The clock could have used numerals to indicate the major minutes but I think since this was for railways it would need to be internationalized so that anyone in the world can understand what time it is just by looking at it.
