UNCHANGING PRECISION FROM THE START TO THE END OF YOUR WATCH’S POWER RESERVE CYCLE – THREE BRANDS SHOW HOW
Select pieces that always stay accurate
It’s not something that you’d typically think about, but mechanical watches are a little like humans. Just as most of us are sharper and more energetic at the start of the day, watches tend to be more precise when fully wound, and less so when their power reserve dwindles. This challenge of undulating precision – known as constant force – has plagued watchmakers since the dawn of mechanical timekeeping. Their holy grail, so to speak, is to find a way that delivers an unvarying rate of energy and torque, so that the watch’s rate of tick-tocking never changes. This year, three brands take on the constant-force challenge, each offering a unique take on how to resolve the issue.
