The Corum Bubble Op Art watch is one of the quirkiest and most eye-catching watches to don the wrist. Featuring an imposing 47mm x 18.8mm diameter, the watch comes in a brown, PVD-coated stainless steel case. The flawless finish on the thickness, curvature and consistency of the sapphire crystal is no mean feat, as its convex design transforms it into a lens that distorts and magnifies the dial. Giving the impression of constant movement, the bubble-like shape emphasises the Op Art pattern on the brass dial underneath. The Corum Bubble Op Art watch is powered by an automatic calibre CO082 movement with a 42-hour power reserve, and is water resistant to 100 metres.
