Roy King was a respected British jeweler and designer known for sculptural silver jewelry and watches. His watches are increasingly collectible because production numbers were relatively low and the styling sits between Cartier Tank aesthetics and British modernist jewelry design. Vintage Roy King RCK Sterling Silver Tank Watch – Black Dial – Swiss Manual Wind – London Hallmarked Description: Rare vintage Roy King (“RCK”) sterling silver tank-style wristwatch dating to the 1970s. This is an elegant British modernist design featuring a stepped square sterling silver case, minimalist black dial, and Swiss manual-wind movement. The caseback carries English hallmarks together with the RCK maker’s mark and “925” sterling silver designation. The watch has a striking architectural presence reminiscent of Cartier Tank styling while remaining distinctly British in execution. The black dial variant is considerably less common than the standard white Roman numeral examples and gives the watch a clean, understated appearance.
