Technical innovation in English watches remained arguably unchanged throughout most of the 18 century. One important innovation was George Graham’s improvement of Thomas Tompion’s cylinder escapement that he employed in his watches from about 1726 until he died. Graham’s watches are known for their high finish quality and this example retains its original solid gold cases. It was acquired from Tom McIntyre, a longtime NAWCC member and volunteer who served in many leadership roles including on the Board of Directors.
