Introduced in the 1990s, IWC's Portofino Perpetual Romana model ref. 2050 is believed to be the slimmest perpetual calendar wristwatch ever made, the movement featuring a thickness of only 3.15 mm. The majority of ref. 2050 was cased in yellow gold, examples in platinum were made in a smaller number only.
