Seamless Studio Product Replacement

Hyper-realistic commercial studio product transformation. A premium studio product setup with a locked-off camera and identical framing throughout. In the exact center of the frame, [a luxury wristwatch] is cleanly replaced by [a flat moss and grass texture patch] occupying the exact same scale and footprint. Lighting: Controlled studio lighting, unchanged reflections, shadows, and neutral background. Camera and Composition: Centered, straight-on locked-off shot, shallow depth of field, static camera. Style: Clean studio realism, physically accurate textures, sharp material detail. Constraints: The organic surface is flat and texture-based only; no vines, no growing animation, no glowing effects, no fantasy elements, and identical environment throughout.
