Lord Lancaster K
1966–1969 · 10k Rolled Gold Plate / Stainless Steel · Manual Wind
About the Lord Lancaster K
Made from 1966 through 1969, the Lord Lancaster K is part of Hamilton's Lord Lancaster family, a line of cushion-case dress watches that ran through the mid-to-late 1960s. The K variant is distinguished by diamonds set at 12, 3, 6, and 9, with applied gold markers filling the remaining positions on a silver butler-finished dial. Power comes from the caliber 681, a 17-jewel manual wind movement. Cases were offered in both 10K white RGP with stainless steel backs and 10K yellow RGP with stainless steel backs, giving buyers a choice between a cooler and warmer palette. The related Darwin shares some design DNA, though the Lord Lancaster K carries its own specific dial layout and diamond placement.
Dial condition is the first thing to scrutinize on one of these. The butler finish can show age unevenly, and the applied gold markers are worth examining closely for any that have shifted or come loose over the decades. Finding one with the diamonds intact and the finish clean across the full dial face is genuinely satisfying. The yellow RGP and white RGP versions each have their advocates, and either makes a strong case for Hamilton's 1960s dress watch design.
From the Catalog
Hamilton's 1966 catalog listed the Lord Lancaster K at $89.50, describing it simply by its 17-jewel movement, 10K white and yellow RGP case, and four diamonds. The pitch was understated, letting the diamond indices and dressy cushion case do the talking.

What to Look For
| Dial | Check the butler finish carefully. Uneven aging or spotting is common, and any clouding around the diamond positions often means moisture got in at some point. Confirm all four diamonds are present at 12, 3, 6, and 9, and look at the applied gold markers to make sure none have loosened or shifted. |
| Crystal | These left the factory with acrylic crystals. Scratches are normal and can usually be polished out, but a deep gouge or a crack is worth factoring into what you're willing to pay. |
| Movement | The caliber 681 is a manual wind, so wind it fully and give it several hours before drawing any conclusions about timekeeping. Dried oil in a movement this age creates enough friction to cause erratic running or outright stopping, even when everything is mechanically sound. A proper service will sort it out. |
| Case | The case is 10K RGP over a stainless steel base, so inspect the high points on the cushion case for wear through to the base metal. Lugs are straight, which makes finding a replacement bracelet or strap relatively straightforward. |
| Crown | Pull the crown gently and make sure it moves smoothly into the winding position without wobble. A loose or sticky crown on a manual wind is worth addressing before regular use. |
The Movement
The caliber 681 is a 17-jewel manual wind movement made by Hamilton. It is a compact, reliable workhorse from this era of Hamilton dress watches, wound via the crown and requiring no battery or rotor. At this age, the lubricants inside will almost certainly need refreshing, but a well-serviced 681 is a dependable and accurate movement.
