Hi ik2000, thanks for the comments.
You're right! The small hand at the subdial at the 12 o'clock position is the year indicator. It shows which year it is in the leap year cycle. It has a slightly larger blued hand for the month. Here's a cropped picture of the subdial.
Cool that you have a RO chrono, I remember seeing your panda. It's an awesome color combo and yours looks great on the strap and bracelet.
