Hamilton Intra-Matic Auto Chrono and Chronograph H homages

Hamilton describes the Intra-Matic Auto Chrono as celebrating its Chronograph A from 1968, with a distinctive panda dial. It was released in 2018, the 50th anniversary of that watch; the original had a 36 mm case and the new one is 40 mm. Hamilton's current press material says the Intra-Matic takes inspiration from the Chrono-matic, its first automatic chronograph, introduced in 1969.

The watch has a 40 mm steel case with a white dial and two black sub-dials, a tachymeter scale and a date, and an automatic H-31 movement with a 60-hour power reserve. Hamilton also sells a hand-wound version, the Intra-Matic Chronograph H, with the H-51 movement.
