Powell
1955–1958 · 10k Yellow Gold Filled / Stainless Steel · Manual Wind
About the Powell
Made from 1955 through 1958, the Hamilton Powell pairs a round 10K yellow Gold Filled case with a stainless steel back and a sterling silver dial fitted with 10K gold markers. The movement inside is Hamilton's caliber 747 or 730, both 17-jewel manual wind movements built in Lancaster, Pennsylvania. The Powell ran for three years in the catalog, available on either a bracelet or a strap, and priced at $65 and $55 respectively depending on configuration.
Dial condition is the first thing to check carefully on a Powell. The silver base is prone to tarnish, and the original finish can peel or fade if the dial has ever been exposed to moisture or a careless cleaning attempt. Known variants include versions with 14K solid gold markers and black-dialed examples, so there is some range in what you might encounter in the wild, and not all dials are interchangeable between examples.
From the Catalog
Hamilton marketed the Powell with straightforward confidence in its materials, calling out the 10K yellow gold-filled case, stainless steel back, and 10K gold markers on a sterling silver dial. At $65 on bracelet or $55 on strap, it landed in the mid-range of Hamilton's 1955 lineup, offering solid American movement quality with a clean, dressy case.

What to Look For
| Dial | The original dial is silver with 10K gold markers. Look closely for tarnish bleed from the silver base, separation of the finish around the markers, or any signs of refinishing. A redone dial kills collector value, and the texture of the original silver surface is fairly easy to spot once you've seen a few. |
| Crystal | These take a domed acrylic crystal. Check for deep scratches or a flat replacement crystal, which changes the look considerably. A correct domed crystal makes a real difference in how the dial reads. |
| Movement | The caliber 747 and 730 are both solid Hamilton movements, but lubricants break down over decades. A Powell that hasn't been serviced recently may run erratically or stop altogether from dried oil creating friction in the gear train. Ask about service history before committing. |
| Case | The case is 10K yellow gold-filled with a stainless steel back. Check the gold-filled surfaces for wear-through at the lugs and case edges, where the base metal starts to show. The swept lug profile can hide thinning, so look at the lug tops closely. |
| Crown | Check that the crown winds smoothly and sets the hands cleanly without slipping. A worn crown on a manual wind watch is a small annoyance that adds up quickly in daily use. |
The Movement
The caliber 747 and 730 are both 17-jewel manual wind movements made by Hamilton in Lancaster, Pennsylvania. They wind from the crown, keep a subseconds dial running off the third wheel, and were built to the quality standards Hamilton maintained for its American-made production throughout the 1950s. Both calibers are well-understood by watchmakers familiar with vintage Hamilton, and parts availability is reasonable.
