Demonstration of the minute hand assembly group of @nordzeitmaschine #CrossNRoll
You can see that the centre of gravity always lying directly above the central pivot point.
Many individual parts of the hand assembly consist of very light materials such as aluminium and titanium. However, in order to achieve the centre of gravity always lying directly above the central pivot point, it was also necessary to use one of the heaviest metals. As such, a balancing weight produced from solid platinum (density 20.7) is mounted on the platform in the front area beneath the pointer tip. This solid platinum weight balances out the somewhat larger and heavier structure at the lower end of the hand assembly.
