Carrera 7753

The Carrera 7753 replaced the two register 3647 in 1969/70. The revisions included the 30 minute register at the “3” position, shorter hour markers and movement change to Valjoux 7730. Heuer also offered a wider variety of dial options including those with scales as well as plain and contrasting colours. Case proportions remained unchanged and featured a signed crown, domed plexi and 18mm lugs.
