Join HSNY on Monday, February 4, 2019 for a lecture on The Secrets of Horological Engine-Turning (Guilloché), by Joshua Shapiro, Watchmaker and Owner of J.N. Shapiro Watches.

The engine-turning technique (guilloché in French) has produced some of the most mesmerizing dials in the history of clock and watch making. Makers such as Breguet, Daniels, Smith, Voutilainen and Murphy have perpetuated this horological art form to the present day. At the same time, much of the history of engine-turning is little-known. At the February 4, 2019, meeting of the Horological Society of New York, Joshua Shapiro will discuss the history and technique of engine-turning.

Shapiro's lecture will delve into the mysteries of engine-turning, beginning with an in-depth look at exactly how engine-turning is done and the differences between the three different types of engine-turning machines. The history of engine-turning will be discussed, as well as the differences between modern and traditional techniques. The lecture will also feature video of engine-turning through a microscope, giving attendees an engine-turning experience from a rarely seen perspective.
