I'd say it's pretty normal. Occasionally you will get lucky and get an A7750 that is in good shape, but most of the time, it's very highly recommended that you get it serviced by a rep friendly watchsmith as soon as you can. You will get many years of reliable use from it if you do.
Also remember - never manually change the date when the time is between 10pm and 2am. (This holds true for the Swiss 7750 as well). It can really mess up the movement.
