If you are at work just put your watch either into your pocket or you may attach it to your ankle ( like my wife does with her Charge 2 ). Unfortunately, steps are made by legs and no watch will be able to detect whether you actually using your legs. This is a downside of all wrist-based trackers. The distance is measured using the stride length. When steps are being detected it considers that you walked the distance of the stride regardless of how long your step was. The 100% accuracy isn't simply possible unless you use the GPS ( and even then, if the elevation gain isn't taken into account, the readings may get wrong ). This isn't a problem with the watch but the problem with the method used. All the watches will suffer the exact same issue.
