Problem is, you don't know the condition of the rest of the movement, so you cannot know the costs to fix. Therefore you can never know whether you received a reasonable price from the dealer or not. Sure, you can roll the dice, but if the dealer treats visible movement parts that carelessly, then I'd have little confidence that non-visible parts were treated well, possibly leading to mechanical issues down the road.
Also, you will not be able to get a quick estimate from PP (will likely have to send the watch in for an meaningful estimate), so your only chance at returning the watch may be now.
