@shai-cristallo did you check if the band or the watch isn’t subject to forces applied by the back of your hand (or wrist movement at all), e.g. when doing push-ups or grabbing weights/ handlebars - anything where you lower arm muscle contract etc.? It looks like you wear it very close to your wrist ankle. I cannot wear it that close during training, because it would be too near and interfere with movement.
