Hey group, Jiusko is a new brand to Massdrop and it is relatively unknown in the watch community. Jiusko offers a high value proposition because they are made in China but they have solid stats (solid end links, tungsten components, dual deployant buckle, sapphire.)
A note about the Miyota 9100 movement is that it's not a true annual calendar. (Which means it doesn't account for odd and even months nor does it account for February.) I got a bit more curious since it's not a very common movement. I found that the popular Junkers Bauhaus uses a similar movement (linked below.) http://www.amazon.com/JUNKERS-Watches-Junkers-Bauhaus-6060-5/dp/B0066GKTM6

lectral13@m_Assdrop already covered it, but it's relatively easy to set the functions. Crown turned counter clockwise changes the day, and crown turned clockwise changes the date. Pusher at 2 o'clock changes the month. (You can use any small object such as push pin or paper clip, but I recommend a wooden toothpick so you avoid the possibility of scratching the case.) You will need to advance the date by 1 click for months that end in 30 days.

Day/date adjusted by crown like any other watch. Month adjusted with pusher. You will need to adjust at end of every month with <31 days.
