Preheat oven to 350°. Remove layer of fat from the top of pork tenderloin with a sharp knife. Pat the tenderloin dry and set aside.
Combine the brown sugar, salt, nutmeg, and turmeric in a small bowl and rub over top and sides of pork tenderloin.
Wrap top and sides of tenderloin with the strips of bacon. Hold in place with toothpicks.
In a large oven-proof skillet, heat oil over medium-high heat. Add the bacon-wrapped tenderloin and sear each side about 6, or until a caramel color.
In a small bowl, combine preserves and mustard. Brush over the top and sides of tenderloin. Transfer skillet to the oven and cook 15-20 minutes, or until tenderloin reaches an internal temperature of 140°F.
Remove from oven and loosely tent with foil while pork continues to cook another 10-15 minutes.
Remove toothpicks and slice into 1/4- to 1/2-inch pieces for serving.
