Using the Mechanik2 Second Hand or Tempus Marker as a Minute Hand Tracker 1. Set the Marker • Use the second hand (Mechanik2 second hand or Tempus marker) as a reference marker on top of the minute hand. 2. Align the Marker • Run the second hand until it aligns perfectly with the current position of the minute hand. 3. Fix the Marker • Stop the second hand at this position. It now serves as a fixed marker indicating the minute hand’s position at that moment. 4. Observe Time Progression • As time passes, watch the movement of the minute hand relative to the fixed second hand. • The minute hand will continue advancing while the second hand remains at its marked position. 5. Use for Measurement • Track how much time has elapsed by noting the difference between the minute hand’s new position and the marked position. Using this method, you can measure elapsed time for up to one hour because the minute hand moves one full revolution in 60 minutes. The second hand serves as a fixed reference, allowing you to track how much time has passed since the initial marking. If you need to measure longer periods, you would need to reset and remark the position accordingly.

This is one of 4 pins for switching the Dual-Mode-Facilitator® (start / stop / reset) of the Mechanik2 annual calendar clock. Note the diameter ( Ø ).

The “jump spring of the months” in the Mechanik2 Series¹ is a refined mechanism designed to manage the transition of the month display within the watch’s annual calendar functionality. The thickness of this part is 0.280 ± 0.010 mm.
