Longines used this family of movements in some very stylish, slender watches throughout the remainder of the 1970s and 1980s. Several years later, the design and tooling for L990 production was sold to Nouvelle Lemania, now also a Swatch Group member. Redesignated Lemania Cal. 8815 in 1991 (with a host of elaborations including skeletonized and full calendar models), these modern Longines 990s have been used as the basis for watches by Ebel, Breguet, Vianney Halter, Roger Dubuis, RGM, Daniel Roth and, Paul Picot, of course, Longines. In 1999 Longines celebrated a significant milestone by introducing a series of gold watches powered by the Lemania 8815. The Longines 30 Millionth Watch limited edition series was a production of 990 watches, all with serial number 30,000,000. The watches were offered in three colors of 18k gold: 390 pieces in yellow, 300 in white and 300 more in pink.
