Narrative:

On a flight to ZZZ we were in cruise flight at FL370. I was the pilot in command. First officer was the pilot flying on that leg. About 1 hour out from ZZZ [very early] in the morning; we started losing the airspeed indicator on the pilot side and eventually went to 0. Then we lost the altimeter and the altitude preselects on the pilot side and the auto pilot stopped working. First officer proceeded to hand fly it off of his instruments. Then the copilot side instruments were starting to read unreliable so we were using the standby altimeter. I decided to [advise ATC of our situation] and they helped us get into ZZZ. It was VFR weather on our time of arrival and we landed with no problem. Maintenance determined it was possible icing in the pitot static system.
