About the Chronomatic E
The Chronomatic E was produced from 1972 through 1974, part of Hamilton's Chronomatic family of automatic chronographs built around the caliber 11 movement developed jointly with Heuer, Breitling, and Büren. The case is stainless steel with a round profile and hidden lugs, giving it a clean, integrated look that was very much in step with early 1970s chronograph design. The two-register dial includes a 1/5-second recorder track, a tachometer scale, and a time zone dial, making it one of the more functionally loaded references in the Chronomatic lineup.
Finding a clean example means paying close attention to the dial, because the tachometer printing on the chapter ring and the recorder track markings are easy to dismiss as wear but can also signal exposure to moisture. The hidden lug design looks sharp when the case is unmolested, but check carefully for signs of forced case back removal, which is a common point of damage on these watches.
From the Catalog
Hamilton marketed the Chronomatic E as a self-winding two-register chronograph with a 1/5-second recorder track, time zone dial, and water resistance, pricing it at $295.00 in the 1972 catalog.

What to Look For
| Dial | Look closely at the two registers and the 1/5-second track printing. Fading or ghosting around the subdial edges can indicate moisture intrusion, which is worth knowing before you commit. The tachometer and time zone markings should be crisp. |
| Crystal | Check for deep scratches or crazing. Replacement crystals exist for this case, but a badly damaged original crystal may have allowed debris into the dial area over the years. |
| Movement | Run the chronograph through a full cycle, start, stop, and reset. The reset in particular can stick or fail to zero properly if the movement has not been serviced in some time. Dried lubricants in a movement this age can stop it entirely or cause erratic timekeeping. |
| Case | The hidden lug design is part of the appeal here, but those integrated lugs can show fatigue cracks at the case body if the watch has been worn hard. Look at the lug-to-case transitions carefully under good light. |
| Crown | The Chronomatic E was rated water resistant, but no vintage watch with seals this old should be trusted in water. Check that the crown screws down or seats correctly and that the stem feels solid with no wobble, which can indicate a worn or replaced crown tube. |
The Movement
The caliber 11 is an automatic chronograph movement born from a collaboration between Hamilton, Heuer, Breitling, and the movement manufacturer Büren in the late 1960s. It uses a micro-rotor for winding, which keeps the movement profile slim for a chronograph, and runs at 19,800 beats per hour. The movement is generally robust but has become increasingly difficult to source parts for, so finding a watch with a documented service history matters more than it might with a simpler movement.
