Item 1 of 2


The G581 was among the very first El Primero chronographs from 1969 in an 18k gold case. Its silhouette is one of elegance, with slim lugs and discreet pushers. Its sporty “panda” dial features a red seconds hand and gold appliqués. Only 150 examples of the G581 were produced in a single batch in 1969, making it a rare and historically significant piece of El Primero history.
