Combine the rosemary, parsley, thyme, garlic, cumin, ¼ cup (2 fl oz) olive oil, lemon zest, orange zest and lemon juice in the small bowl of a food processor. Process to a coarse puree. Spoon the puree into a bowl and set aside.
Combine the mustard, honey and remaining oil in a small bowl and mix well.
Unroll the lamb and place fat side down between 2 pieces of plastic wrap. Make a few shallow cuts in the thicker portions of the lamb, this will help it to flatten more easily when pounding. Pound the lamb using a rolling pin or meat mallet to about ¾ inch thick, creating a rectangular shape.
Season both sides of the lamb with salt and pepper, then place the lamb on a board fat side down. Spread the herb and citrus puree evenly over the lamb.
Starting from a short side, tightly roll the lamb. Using kitchen twine, tie at 1 inch intervals to secure the lamb and create a round shape.
Put the lamb in the roasting pan. Brush all over with the mustard mixture. Put the lemon, cut side down in the pan.
Insert the wire rack in the bottom shelf position. Preheat the oven. Select ROAST/325°F/65 minutes.
Once preheated, put the lamb in the oven and cook for 65 minutes for medium-rare.
Transfer the lamb to a plate, cover loosely with foil and set aside to rest for 20 minutes.
Arrange the watercress on a serving platter, top with the lamb and roasted lemon. Slice and serve.
