Watchmaker Retires After 50 Years, Hands Shake Too Much to Wind Watch but Perfectly Steady for Surgery

Master watchmaker Bernhard Kessler, 72, has announced his retirement after a 50-year career, citing an essential tremor that makes daily tasks like pouring coffee, signing documents, and winding his personal watch 'an adventure in fluid dynamics.' The tremor, however, vanishes completely the moment Kessler picks up watchmaking tweezers and positions them over an open movement. 'It's the damnedest thing,' said his neurologist, Dr. Anna Schreiber. 'His hands shake visibly at rest. They shake holding a fork. They shake holding a pen. But the moment he seats a hairspring collet, his hands become the steadiest instruments I have ever measured. His tremor amplitude drops to zero. It's as if his nervous system recognizes the movement and decides this is not the time.' Kessler discovered the phenomenon approximately five years ago, when his tremor first became noticeable. Initially concerned that his career was over, he found that the shaking stopped 'like a switch' each time he began working. 'I can't butter toast,' Kessler said, demonstrating by attempting to spread butter on a piece of bread with visible difficulty. 'But watch this.' He picked up a pair of Dumont No. 5 tweezers, opened a Valjoux 7750 calibre, and proceeded to replace a pallet fork with movements so fluid and precise that Dr. Schreiber, who was observing, described them as 'indistinguishable from a surgical robot.' Kessler's retirement is therefore not due to inability but to what he calls 'the logistics problem': he can no longer reliably carry a cup of coffee to his workbench without incident, and 'a watchmaker without coffee is not a watchmaker.' His final professional act was servicing his own watch — a 1960s Omega Constellation — which he wound, regulated, and returned to his wrist with tremor-free precision, before immediately spilling his celebratory champagne.
