Rough start to the morning. Dropped my Orient Bambino on the floor. It landed perfectly flat on the back of the case. Picked it up and sure enough, the second hand wasn't moving. I wore it all day yesterday, so it wasn't out of power. Tried pulling pulling the crown out and moving the hands to see if that would restart it. No luck. So, what do I do now? Worth getting it serviced? What is it likely to cost? Or should I just replace it?
