Signo
Credor's long-running dress and jewelry-watch line, active since around 1990 (no source pins an exact launch date; references from the 90s and early 2000s are the earliest documented) and sitting below the Eichi and Spring Drive Tourbillon in the catalog hierarchy but still built to Credor's precious-metal-and-diamond-setting standard. The Signo is the collection most Credor buyers actually encounter day to day, spanning quartz and mechanical references aimed at the Japanese domestic dress-watch market.
