Yes, the Oris caliber 400’s minute hand actually does jump when setting the time.

The Oris caliber 400 is an in-house movement that was released to the market with a known minute hand issue, which jumps both when setting the time while the crown is in the time-setting position, and when the crown is pushed back in.

At this point in time, Oris still has not fixed the issue, nor publicly addressed it, which is, of course, concerning.

Whether watches powered by the otherwise impressive Oris caliber 400 are a good option is subjective, and to help you make a better decision, master watchmaker Jordan Ficklin produced an in-depth written review and video on the subject, which provides a definitive answer to what the issue is, including a technical explanation of why it occurs, plus a workaround (hack).
