is the thermostat on its way out ?

hi ive only recently purchased my 197 and not sure if this is normal it takes around 15-20 mins for the temp needle to go to the 3rd point just under halfway is this completely normal and im just picking or is it on its way out. any help will be appreciated
 
ok thank not sure if its anything to do with the climate control when have it off warms up alot quicker id say 5 mins when its on take a fair bit longer
 
Thats normal, with heating/aircon on, brings on the radiator fan. Normal sits just after the second mark, due to the cooler runing thermostate
