Rolex's 1978 Technical and Service Information describes Cal. 2030 as automatic, with sweep seconds, 28 jewels and hacking. It distinguishes the calendar-equipped Cal. 2035. Sotheby's and Antiquorum catalogue Cal. 2030 in individual 6718 watches. The exact-reference catalogues document those individual fitments; broader 6718 fitment and production dates remain unresolved.

Christie's, Antiquorum, and Hindman also catalogue Cal. 2030 in individual 6719 watches; only Antiquorum and Hindman list 28 jewels. These lots document examples, not the full fitment span.
