I have had my Aquis 7730 for less than a year. On full power (20 turns or so of the crown) the watch gains a very respectable 3 or seconds a day. I happy with that. The problem is with constant wear for more than week, the acurracy gets progressively worse LOSING seonds a day. I understand the nuances of the SW movement, but it appears when the power reserve is reducing it accelerates in losing seconds. In addition I would have thought general wear would maintain a reasonable level of power reserve?
Should i ge the watch serviced or is this normal. Thoughts appreciated.
