Sir Echo
1957–1964 · 14k Solid White Gold, 14k Solid Yellow Gold · Manual Wind
About the Sir Echo
Made from 1957 through 1964, the Sir Echo is a dressy round-cased Hamilton offered in 14K yellow or white gold, powered by the manual-wind caliber 770 with 22 jewels. The Sir Echo is closely related to the Echo, sharing the same case architecture and dial sensibility but with its own distinct dial configuration. Across its production run, the Sir Echo appeared with several dial variants, including a silver dial with applied gold markers and dots, versions with diamonds set into the dial, and configurations with numerals at 12 and 6. The white gold version featured rhodium-plated markers to match the cooler tone of the case.
Dial variation is the most interesting part of tracking down a Sir Echo. The 1957 configuration featured 14K gold markers and two diamonds on a silver dial, while the 1963 catalogs show six diamonds. Finding a clean, unpolished example in either yellow or white gold with the original dial intact is the real goal, since silver dials can develop a patina or show spotting if they have been exposed to moisture over the decades. The case and dial combination reward close inspection.
From the Catalog
Hamilton's 1957 catalog listed the Sir Echo at $165.00, describing it as having 14K gold markers and two diamonds on a sterling silver dial, available in yellow or white gold. By 1963, the diamond count had grown to six, and Hamilton was positioning it on a black suede strap as a straightforward dress watch at the upper end of their gold catalog range.

What to Look For
| Dial | Silver dials can develop spotting or uneven patina over time. Check for separation or missing applied gold markers or diamond indices. Confirm whether the dial matches the case metal, since the white gold version should have rhodium-plated markers rather than warm yellow gold. Hairline cracks or refinishing are worth looking for closely. |
| Crystal | Check for deep scratches, chips, or crazing. A replacement crystal is fine, but make sure it fits the case correctly and does not sit proud of the bezel or have any gaps around the edge. |
| Movement | Lubricants in the caliber 770 dry out over decades, and a movement running on spent oil builds friction and wears parts faster than it should. Ask whether the watch has been recently serviced and, if possible, by whom. |
| Case | Examine the case for signs of over-polishing, which can soften the original lines. In a 14K gold case, look at the lug edges and case profile for that rounded, worn-down look that comes from repeated buffing. Verify the case metal is stamped correctly, either 14K yellow or white gold. |
| Crown | The crown should feel smooth and positive when winding, with no slipping or grinding. A loose or wobbling crown can indicate wear to the stem or crown threads. On a dress watch this age, the crown is easy to overlook, but it affects daily usability. |
The Movement
The caliber 770 is a 12/0-size manual-wind movement running at 18,800 beats per hour with 22 jewels, which was Hamilton's higher jewel count for this caliber family and indicates additional friction-reducing jeweling throughout the gear train. It is a reliable, well-built movement that Hamilton used across a range of dress watches through this era. The subseconds hand runs at the 6 o'clock position, which is a clean fit for the Sir Echo's symmetric dial layout.
