Diamonds are a movement’s best friend. As well as sapphires and rubies. Synthetic rubies, for example, do not only decorate our timepieces but also serve specific functions as bearing jewels, endstones or pallet-stones purposes in the movement. Where friction on moving parts must be minimised within the mechanical movement, a polished ruby can be implemented to ensure superb smoothness. When enhanced material or wear resistance is required, synthetic rubies do an excellent job due to their hardness. Nowadays, they replace natural rubies in watchmaking because they are even more homogeneous in their crystal structure. #alangesoehne #langesaxonia #datographupdown #langestoryettes #timepieceperfection
