You don't say how long it actually took to lose 5 minutes. Did you just notice it lost 5 mins 2 days ago but was it correct the day before then? What is the actual daily rate loss. Any new watch or recently serviced watch will naturally run faster for the first few months. Once the oil settles the watch can typically run many seconds slower than initial accuracy. However I have never experienced a watch running several minutes slower or faster after several months. If the watch is say 10 seconds slower daily then I would say it simply needs re-regulating. A very simple procedure & def not needing a trip to Swiz. If the watch is running more than 1 minute slower (or faster) than originally then I would say there is probably a more serious issue...like an out of beat balance or severe friction in the rotor auto winding mechanism causing constant below par wind energy.
