The Chrono-Matic A, released in 1969, was a groundbreaking piece, featuring a 37mm round case and the distinctive panda dial. Powered by the innovative Caliber 11, this model was part of an industry-wide race to master the automatic chronograph, marking a pivotal moment in watchmaking history. Fast forward to today, the legacy continues with the Hamilton Intra-Matic Chronograph Black. This modern iteration comes in a 40mm stainless steel case with a light green dial, luminescent hands, and a tachymeter scale. It houses the Calibre H-31, based on the ETA/Valjoux 7753, which offers a substantial 60-hour power reserve and features a quick date adjustment at 10 o’clock. Both models exemplify Hamilton’s ongoing commitment to innovation and style, from the race tracks of the 1960s to today’s fashion-forward wrists.The Intra-Matic Chronograph Black is available with either a leather strap or a mesh bracelet, priced at USD 2,295 and CHF 2,345 respectively.
