More commonly known as Côtes de Genève, a surface decoration of even, undulating, parallel lines, like waves, applied on the flat surfaces of high quality watch movements.
"A form of decoration in higher grade watch movements which look like stripes on the movement plates. These used to be applied by hand; in many cases in modern times, they are applied by machine." Tim Temple Watches (http://www.timtemplewatches.com)
"Famous wavelike decorative pattern created on the bridges and oscillating weights of Patek Philippe watches. The tool required is crafted from boxwood by the craftsman himself, coated in abrasive paste and then pressed manually in order to remove an extremely small amount of material." (www.patekphilippe.com)
"Elegant ribbed decoration applied to the plates, bridges, and cocks (movement parts) of exclusive watch movements." Luxois.com
