Season steaks on both sides with pepper, lightly patting it on. Place a large cast-iron skillet over medium-high heat (I used medium-low and preheated the pan while I prepared the recipes). Season steaks to taste with salt, then place in dry skillet. Sear steaks without moving them until they are brown and crusty, about 4 minutes per side for medium-rare.
Pour off fat and add wine to skillet. Cook over low heat (I left heat at medium-low) until wine is reduced by half, about 30 seconds. Pour wine reduction over steaks.
Wipe out skillet and return to medium-low heat. Melt butter in skillet and add watercress. Toss until wilted, about 1 minute. Season with salt and pepper.
To serve, cut steaks in half. Place a portion on each of four plates accompanied by a serving of watercress.
