Heat oven to 425 degrees. Place beets in roasting pan with 1/4 inch water. Seal tightly with aluminum and roast until tender, about 1 hour. When cool enough to handle, slip off and discard skins. Thinly slice 1/8-inch by hand or on mandoline. For uniform pieces, you can cut again with small round or square cookie cutter.
Combine goat cheese, chives, and lemon zest and mix well. Place one beet slice in center of plate. Place a teaspoon or so of cheese mix in center. Place second beet on top and gently push to force cheese out to edge. Repeat with as many layers as you like (3 to 4 works well).
Scatter watercress and orange salad around the outside of plate. Sprinkle with almonds. Serve.
