Forerunner showing signs of water damage

I have been the proud owner of a Forerunner 945 since 2019. As of the last 7 days I am seeing moisture build up on the watch face. I have tried a few tactics to dispel the water including using silica outsized dessicant packets. I was hoping my watch would remain robust for longer than this. Please advise. I have a half marathon this week so have been enjoying using the watch to track my training schedule and build up to the event. Has anyone experienced similar?
