I've had to send in a few watches I've bought secondhand, after screws or other parts came loose. The watches were always well-packed, but sometimes these things happen. It's very frustrating, the first few months of owning a new watch are the best. I agree that unknown repair cost is a stress that is not needed in life, even when funds are readily available to cover it. Fortunately, the repair is unlikely to be a major issue and Laurent Ferrier is likely to cover the repair under warranty. Independent brands tend to appreciate all owners, whether they bought new or secondhand.
