Heat oven to 375 degrees. Wrap bacon around chestnuts; secure with toothpicks. Mix sugar with the water in a small bowl. Place chestnuts on rimmed baking sheet; brush with glaze. Bake until bacon is crispy, about 20 minutes, brushing with glaze midway through. Remove from oven, glaze again, and serve immediately.
