Reference 5970 was introduced to the market at the Baselworld in April 2005 and replaced the celebrated reference 3970. The model immediately enjoyed popularity amongst collectors and was available in white gold or pink gold only until 2007 when the production of these two versions ceased. Reference 5970 in yellow gold was in production only in 2008. In 2008, the model was made exclusively in platinum.
