Use the provided white-background product image as the locked reference. Preserve the steel dive watch exactly: black dial, steel bezel, orange seconds hand, crown, steel bracelet with dark central links, all dial markings, proportions, and diagonal suspended angle. Create a refined vertical watch poster in a pale mineral-gray gallery. Frame the floating watch with two differently shaped chalk-white stone blocks, one rough and one smooth, with minimal soft shadows. Change the block geometry, positioning, camera crop, and lighting direction clearly from the source while retaining the minimalist monochrome editorial mood. Constraints: one watch only; no watermark, poster text, people, hands, duplicate watches, altered bracelet, altered bezel, altered dial, or unreadable markings.
