With vertical windows at 12 and 6 for the day and the month, a retrograde date indicator around the edge of the main time display and a neat little porthole at 3 o'clock to show the year (counting up from 1 to 4 for each leap year), there's nothing typical about it. Perhaps the most impressive feature, however, is the openworked seconds indicator at 9 o'clock, which has been engineered to rotate clockwise whether you're looking at it from the front or the back.
