For something mechanical operating under random g forces and over a wide temperature range, that accuracy is truly astonishing.

- kenneth 5y agoFully agree, automatic mechanical watch movements are truly a marvel of engineering. The fact that the movement is powered purely by the kinetic forces naturally applied from wearing it, and can reasonably accurately keep time over years, under a wide range of conditions… is truly impressive.
