The Caliber 11 is one of the very first automatic chronograph movements ever produced. During the 1960s, many major watch brands were competing to reach this milestone first, and rivalries were high between Seiko, Zenith, and the Buren group, which was composed of Breitling, Heuer, and Hamilton. The Buren Group’s race to the automatic chronograph is said to have been secretly named ‘Project 99’ and once completed, the involved brands powered many of their various chronograph models with this highly innovative and groundbreaking movement. Cue the beloved and truly fantastic Hamilton Chrono-Matic.

In addition to being one of Hamilton’s most famous and best-looking chronograph models of all time, the Chrono-Matic ref. 11002-3 also holds the distinction of being one of the world’s very first automatic chronograph watches, as it debuted in 1969 - the very same year that the first self-winding chronograph movements were making their inaugural appearances. Featuring a two-register layout, a date display at 6 o’clock, and an integrated micro-rotor design, the Cal. 11 represented a major step forward for the world of chronographs and the Hamilton Chrono-Matic ref. 11002-3 is easily one of the most important models from the brand’s archives.

CASE & BRACELET 

The excellent case retains crisp lines with thick, symmetrical lugs and light signs of honest use present. The watch retains its original Hamilton-signed crown and pump pushers. The case back retains all of its factory markings in fully present and original condition. The watch comes supplied on a 2pc handmade leather strap.

DIAL & HANDS

The reverse panda, matte white dial with black sub-dials, is exceptionally well preserved with no damage or notable elements of age present. The tritium lume plots have taken on a subtle creamy patina, under UV light inspection all the lume plots remain intact though light degradation is present throughout. The tritium lume in the hour and minute hands matches the dial perfectly and display no degradation. The black center chronograph hand completes the contrast heavy dial design.
