About the Automatic K-414
Made only in 1960, the Automatic K-414 is a 17-jewel automatic in a round 10K yellow Gold Filled case, powered by Hamilton's caliber 667. It belongs to Hamilton's broader Automatic family, a line of self-winding dress watches that were positioned as everyday-wearable alternatives to Hamilton's manual-wind models. The dial is white with embossed gold numerals and markers, a pearlized track, and lumed hands, giving it a finished, formal look that was well suited to the $95 price point at the time.
Surviving examples tend to show their age most visibly on the dial, where the pearlized track can cloud or flake if the watch was exposed to moisture over the decades. The embossed numerals hold up better than printed dials typically do, but look closely for any separation or corrosion around the markers. The 661 and 665 are closely related models and worth knowing if you're trying to understand where the K-414 fits in Hamilton's automatic lineup for that year.
From the Catalog
Hamilton described the K-414 as featuring a 10K yellow gold-filled case with yellow embossed numerals, luminous markers, and a pearled track, and listed it as weatherproof. It retailed for $95 in 1960.

What to Look For
| Dial | Inspect the pearlized track carefully. It can cloud, flake, or separate from the dial surface on examples that have seen any moisture exposure. The embossed gold numerals and markers are more durable, but check for separation at the edges. Lume on the hands and dial should be evaluated for condition and color consistency. |
| Crystal | The original crystal is acrylic. Light scratches can be polished out, but deep gouges or crazing mean a replacement is needed. Make sure the crystal sits flush with no gaps around the bezel, which can let dust or moisture reach the dial. |
| Movement | The caliber 667 is an automatic and should wind from normal wrist motion. Any movement this age running on original lubricants is running on dried oil, and dried oil generates friction that can stop the watch or cause irregular timekeeping. A service is worth budgeting for if the watch hasn't been opened recently. |
| Case | The 10K yellow gold-filled case will show wear through the plating at contact points over time, typically the lugs and caseback edges. Look for any deep scratches or brass showing through the GF layer. The caseback on these can be tight and require the right tool to open without leaving marks. |
| Crown | Check that the crown screws down or seats properly and that the stem feels solid without wobble. On the caliber 667, hand-winding is a bit awkward given crown access, so confirm the automatic winding side is functioning. A crown that spins freely without engaging the movement usually means a worn or broken stem. |
The Movement
The caliber 667 is a 17-jewel automatic movement made by Hamilton for their American-market dress watches of this period. It winds from wrist motion via a rotor, so it doesn't need daily manual winding under normal wear conditions. Watchmakers familiar with the 667 know that reassembly requires patience, as the train bridge involves lining up multiple wheels simultaneously, making it a movement that rewards a careful, unhurried approach on the bench.
