European Watch Clock and Jewellery Fair 1992 BF 131
The Concord Delirium collection reflecting the ongoing development of the world’s thinnest wristwatch (the Delirium IV, introduced in 1981, only 0.98 mm thick), now includes a platinum design for men. Water-resistant to 20 m, it features a sapphire crystal and an alligator strap. A date calendar at 6 o’clock provides the dial with an unexpected touch. Its quartz movement is one of the thinnest made. (CONCORD “Delirium Platinum”)
