The special moment that proud owners of ochs und junior perpetual calendars have been waiting for— for up to 4 years — is nearly here. Their watches will correctly display the dates February 28th and 29th and move seamlessly into March 1st, merely through the interactions of 9 components, including a Maltese cross that will take the lead role in this extraordinary mechanical performance. Truly one small step for this ingeniously simply mechanism, but one giant leap for all owners of such a perpetual calendar! Link to perpetual calendar video.
