Edgemere B
1956–1958 · 10k Yellow Gold Filled · Manual Wind
About the Edgemere B
Made from 1956 through 1958, the Edgemere B belongs to Hamilton's Medallion family and runs on the caliber 770, a 22-jewel manual wind movement. The case is 10K yellow Gold Filled, round in shape, and the dial is a sterling silver face dressed with 14K gold markers or numerals depending on the variant. That combination of sterling silver and 14K gold hardware put this one toward the upper end of Hamilton's dress watch lineup for its era.
Silver dials can develop a soft patina or light oxidation over the decades, which reads differently depending on how the watch was stored. A dial that shows even, undisturbed aging is generally preferable to one that's been cleaned or touched up. The 14K gold applied markers are a detail worth confirming in person, since replacements or redial work can alter the character of the watch significantly.
From the Catalog
Hamilton described the Edgemere B as a 10K yellow gold-filled case with 14K gold markers or numerals on a sterling silver dial. In 1957, it retailed for $89.50 on a strap or $95.00 on a bracelet, placing it among Hamilton's more serious dress offerings of the period.

What to Look For
| Dial | Silver dials are vulnerable to moisture and improper storage. Look for even surface color without dark spots, detached markers, or signs that the dial has been refinished. The applied gold markers should sit flush and show consistent color. |
| Crystal | Check for deep scratches or crazing on the crystal. A replacement acrylic crystal is easy and inexpensive, but confirm the profile fits correctly over the dial. |
| Movement | Ask about service history. The movement ring on the caliber 770 is prone to verdigris, a greenish corrosion that can spread to the movement itself if left unaddressed. A watch that's been sitting unworn for years should be serviced before regular use. |
| Case | Gold-filled cases can show brass bleed-through at high-wear points like the lugs and caseback edge. Check those areas carefully. The case back on some Medallion models can be stubborn to open without the right tools, so avoid anything that looks like it's been pried. |
| Crown | Test the crown through all positions. It should pull out cleanly and wind with smooth resistance. A crown that slips, feels gritty, or won't seat properly may indicate a worn stem or crown, both of which are serviceable but worth factoring in. |
The Movement
The caliber 770 is a 22-jewel manual wind movement made by Hamilton in Lancaster, Pennsylvania. The higher jewel count compared to Hamilton's standard dress movements reflects the Medallion line's position as a premium offering. It's a well-regarded movement among collectors, known for keeping good time when properly serviced, though like any vintage movement it needs fresh oil and a full service to perform as intended.
