[Create a photorealistic luxury menswear studio portrait of a sophisticated, well-groomed man wearing a minimalist wristwatch. Dress him in a precisely fitted light-grey, textured three-piece suit consisting of a tailored jacket, matching waistcoat, and trousers, complemented by a spotless white formal shirt and a narrow charcoal-grey tie. Position him beside a subtly textured concrete-grey wall. His body should be turned slightly away from the camera in a natural three-quarter stance, while his face looks toward the side with a composed, self-assured expression. Both hands are positioned around the chest area, naturally adjusting the front of his jacket. Use soft, diffused professional studio illumination that reveals the fine weave of the suit and preserves realistic skin detail. Maintain a shallow depth of field with the face as the primary focus. Simulate a full-frame professional camera using an 85mm portrait lens at approximately f/1.8. The overall aesthetic should feel like a premium men's fashion campaign: sophisticated, understated, modern, and monochromatic, with subtle variations of grey throughout the clothing and background. Preserve realistic skin pores, natural facial detail, authentic fabric texture, refined tailoring, and high-end photographic clarity. Composition: vertical portrait, 4:5 aspect ratio, balanced framing, comfortable headroom, elegant posture, crisp facial focus, photorealistic finish, ultra-detailed high-resolution quality.]
