C560XL Captain reported a Flashing HYD PRESS with a Master Caution after flap retraction. Flight crew continued to destination and landed.

Narrative

On takeoff we received a Flashing HYD PRESS with a Master Caution after flap retraction. Gear and flaps were retracted on schedule. We had the following conditions. HYD PRESS; nose gear unlock light; and a STAB MIS COMP. We ran HYD PRESS QRH. Pulled and reset HYD Control CB as per the QRH. We maintained 200 KTS and FL310 as per the QRH. HYD PRESS remained illuminated for 30 min just prior to landing. And HYD PRESS light extinguished. The STAB MIS COMP Stayed on and we still had a nose gear unlock light. prior to commencing our approach we put down gear and flaps. We had normal indications. We had three green for gear and STAB MIS COMP extinguished. In our decision making; after running the QRH with the HYD PRESS on; we decided to divert to an airport with a longer Runway. Initially we were going from ZZZ to ZZZ1 and decided to use ZZZ2 with its XX000 feet runway verses ZZZ1 XX00 feet runway. Taking into consideration any further HYD complications; loss of flaps and gear. We made the decision to [request priority handling] with ZZZ; as we could not comply with speeds on the ZZZZZ arrival as we were restricted at 200 KTS in the descent; also the potential to not have flaps and possible gear extension. We got delaying vectors prior to commencing the approach; to put down gear and flaps to see if there would be any further complications.
