In a Dutch oven, cook bacon over medium heat until crisp. Remove to paper towels to drain; set aside. Saute celery and onion in the drippings until tender. Add garlic; cook 1 minute longer. Stir in the potatoes, water, clam juice, bouillon, pepper and thyme. Bring to a boil. Reduce heat; simmer, uncovered, for 15-20 minutes or until potatoes are tender.
In a small bowl, combine flour and 1 cup half-and-half until smooth. Gradually stir into soup. Bring to a boil; cook and stir for 1-2 minutes or until thickened.
Stir in clams and remaining half-and-half; heat through (do not boil). Crumble the cooked bacon; sprinkle over each serving.
