Heat a large Dutch oven with a tight-fitting lid over medium-high heat. Pour in enough oil to fill the pan about 1/4-inch deep. Season the beef generously with salt and pepper, and add to the pan. Saute the meat, uncovered, stirring only occasionally, until well-browned, about 8 minutes. Using a slotted spoon, transfer the beef to a plate. Repeat with the remaining beef. Discard the oil and wipe out the pan.
Preheat the oven to 325 degrees F. Return the pot to the stove and melt the butter over medium high heat. Add the onion and cook, stirring, until lightly browned, about 5 minutes. Add the garlic and cook, stirring, until fragrant, about 1 minute. Add the tomato paste and cook, stirring, until lightly browned, about 1 minute more. Add the reserved beef and scatter the flour over the vegetable and beef mixture (enough to lightly coat) and cook stirring until lightly toasted. Add the water or broth, and bring to a simmer. Tie the parsley, thyme, and bay leaves together with a piece of kitchen twine and add the bundle to the pot. Season with 2 teaspoons salt, or to taste. Cover and transfer to the oven. Cook the meat until just tender, about 1 1/2 hours. (This can also be done on the stove at a low simmer.)
Remove pot from the oven. Skim the fat from the cooking liquid with a spoon or ladle. Add the potatoes, carrots, celery, and the tomatoes, and bring to a simmer on top of the stove. Cook, uncovered, stirring occasionally, until the liquid thickens and the vegetables are tender, about 1 hour. Remove and discard the herb bundle. Stir in the vinegar and season with salt and pepper, to taste. Divide among bowls and serve immediately.
Cook's Note: Beef chuck, from the shoulder, because of its marbling of intra-muscular fat, is the choice for any type of stew. If you can't find chuck cubed for stew in your meat department, buy a thick chuck steak and cut it into 2-inch cubes.
