The seller says this dial has a diameter of 26.72 mm. Now that is smaller than an 0-size Hamilton dial (27.8 mm), but larger than a 6/0 size (24.1 mm) - and anyway the seconds register is too high for either, and it has only 2 dial feet. However the dial signature and numbering looks fine for 1920 or earlier.

So what is it for ?

Here is the back view --- any suggestions as to movement ?

I suspect that this is from the reproduction "Lady Hamilton" that was produced 20-30 years ago by the Hamilton Watch Company, Collector's Classic Edition Society Division. Like the "Lord Hamilton" pocketwatch of the same era, I am pretty certain it would have had a Swiss movement.

To help confirm that Jerry is correct, isn't that a "SWISS" marking at the edge below "6"?
