YOOTEN Men's Automatic Waterproof Luminous Mechanical Watch - Self-Winding Dress Watch for Business, Casual & Outdoor Activities

I purchased your Carnival 1986 # 8756G on March 20th. I love everything about the watch except for the fact, that over two days, it is already 30 seconds slow. That is 15 seconds a day which puts the watch I purchased way below the normally accepted accuracy of 99.994% of 4 to 6 seconds a day for a mechanical watch. At that rate, it will be one minute off in 4 days. This is my second Carnival watch of this style and my first was very accurate. What should I do? It can be adjusted at some cost to me which I want to avoid. I could return it which I'd like not to do. What do you suggest I do in this case? Thanks.
