About the Chronomatic D
The Chronomatic D is part of Hamilton's Chronomatic family, the brand's line of automatic chronograph watches that arrived as the industry was working through the first generation of self-winding chronograph movements. Produced from 1971 through 1974 in stainless steel, the Chronomatic D offered a two-register dial layout with a 1/5-second recorder track and a time zone dial, giving it a functional depth that went beyond simple elapsed-time measurement. The round case features A design detail that was firmly in the idiom of sport and professional chronographs of that era.
Finding a clean example means paying close attention to the dial, where the time zone chapter and recorder track printing are prone to fading or spotting after five decades.
From the Catalog
Hamilton described the Chronomatic D as a self-winding chronograph with a two-register dial, 1/5-second recorder track, and time zone dial, priced at $295.00 in 1972, which positioned it as a serious instrument watch rather than a dress piece.

What to Look For
| Dial | Examine the time zone dial and the 1/5-second recorder track closely. Printed details like these are vulnerable to moisture and age, and fading or discoloration in the chapter ring area is common. Check the applied indices for separation or tarnishing at the edges, which can signal past moisture intrusion. |
| Crystal | Confirm the crystal is correct for the model. A replacement that sits too high or low relative to the bezel edge is a sign the wrong part was fitted, which can affect the seal and the overall appearance of the dial through the glass. |
| Movement | Dried lubricants in a movement this age can create enough friction to stop it entirely or cause erratic timekeeping. Ask about service history, and if the chronograph hasn't been serviced in the last several years, factor that cost into what you're willing to spend. |
| Case | Look at the junction between the hood and the case body for pitting, deep scratches, or uneven polishing from previous attempts to refinish the watch. |
| Crown | The original water resistance rating is not something to rely on in a vintage watch. Check the crown for correct operation through all positions, and inspect the stem for any wobble that might suggest a damaged or worn crown tube. |
