Blade
1962–1969 · 10k White / Yellow Gold Filled · Manual Wind
About the Blade
Made from 1962 through 1969, the Hamilton Blade is one of the more striking asymmetrical case designs Hamilton produced during that era, pairing a rectangular dial with a sculpted case that pushes away from the conventional round-or-rectangle binary of the period. It runs on Hamilton's American-made caliber 770, a 22-jewel manual wind movement. The Blade was offered in both 10K yellow Gold Filled and 10K white Gold Filled cases, giving collectors two distinct looks from the same reference. The Lord Lancaster C is a closely related model worth knowing if the Blade is on your radar.
Finding a Blade in honest condition takes some patience. The asymmetrical case shape means wear tends to show unevenly, with the more pronounced lugs and angles catching more contact than a conventional case would. Dial variants add some interest here: known examples exist with gold markers on a white dial and with a radially finished dial surface, so the dial you find on any given Blade may differ from catalog photographs. The painted markers and Hamilton logo are worth close inspection, as touch-ups are common on watches from this period and not always obvious at a glance.
From the Catalog
Hamilton marketed the Blade in 1962 with straightforward emphasis on its gold-filled case construction, offering it in both white and yellow gold-filled versions at $89.50, which placed it in the mid-range of Hamilton's dress watch lineup for that year.

What to Look For
| Dial | Check the painted black markers and any gold dot indices carefully under good light. Repainted or retouched dials are common on watches this age, and the brushwork around small markers is usually where touch-ups give themselves away. The Hamilton logo should be clean and consistent with the rest of the dial finish. If the example has a radially finished dial, look for any peeling or flaking at the edges where finishing meets the chapter ring. |
| Crystal | The Blade takes a flat or low-profile crystal. Inspect for deep scratches or chips at the edges, which are harder to address on asymmetrical cases where fitting a replacement requires careful sizing. A fogged or yellowed crystal usually means the original has never been replaced and is well past its useful life. |
| Movement | The caliber 770 is a manual wind and needs to be wound regularly. Lubricants dry out on movements this age, and dried oil creates enough friction to stop the watch entirely or cause erratic timekeeping even when the watch appears to be running. A movement that runs when wound but stops after a few hours is a classic sign of dried lubrication, not a sign the movement is worn out. |
| Case | The asymmetrical case shape wears differently than a conventional round or rectangular case, so inspect all surfaces, not just the flat top. Look at the lugs and the angular transitions for deep dings or polishing that has softened the original lines. The movement ring inside the case is prone to verdigris, which is worth checking if the case back has been opened. |
| Crown | Confirm the crown is original to the watch and threads or seats properly. A replacement crown that does not match the case finish or profile is a small detail that affects the overall presentation on a dress watch like this one. Also note that this watch is not suitable for water exposure regardless of any original ratings. |
The Movement
The caliber 770 is an American-made Hamilton movement, manual wind with 22 jewels and shock resistance. It is one of Hamilton's more refined domestic calibers from this period, known for good reliability when properly serviced. Winding is done through the crown, and the movement should run steadily for a full day or more on a complete wind when in good service condition.
