Thoroughly rinse the chicken with cold water and pat dry. Sprinkle with 1/2 teaspoon each salt and pepper.
In a deep skillet, heat the oil over medium heat until it is hot but not smoking. Add the chicken in one layer and reduce the heat to medium-low. Slowly brown the chicken, turning occasionally, for 1 hour.
Pour 4 cups water over the chicken, raise the heat to medium-high and bring to a simmer. Add the apricots, tamarind concentrate, apricot preserves, chipotles and 1/2 teaspoon salt, stirring until incorporated. Keep the liquid at a medium simmer over medium heat until the sauce is thick enough to coat the back of a wooden spoon, 35 to 40 minutes.
Taste the sauce for seasoning and heat, adding more salt or chipotles if desired. Transfer the chicken to a platter and drizzle with the sauce.
