 Lost GPS whole day. After restart with upper button pressed 12 sec all ok. 
 My watch: Spartan sport WHR. Is it a common problem?

 I’ve had the same problem a few times with the latest firmware (SSU). 12sec soft reset fixes the problem temporarily. Reported to Suunto some time ago but haven’t heard anything yet… hopefully a new firmware will come soon. Rather annoying.
