Experience the NAWCC’s Mission in School of Horology Classes

The NAWCC is committed to being the world leader, educator, and advocate for horology and for everyone interested in timepieces and the art and science of timekeeping.

The NAWCC School of Horology is located in Columbia, PA, and its educational programs serve to stimulate interest in and preserve knowledge of horological crafts. We look forward to welcoming you to future classes.

A Message from the Education Director, Ken De Lucca 

As we renew and revitalize the School of Horology, our focus is on the four basics that should exist in any such school: 

  • Clock Education
  • Watch Education
  • Machining Technology for Horology 
  • Decorative Techniques such as Stenciling and Under-glass Painting

At the School of Horology, we are indeed fortunate. We have the square footage and the equipment and supplies to provide top-notch educational opportunities. Expert instructors will be engaged in their area of specialty to offer learning experiences for students of horology.

This is an exciting time to be a part of NAWCC’s School of Horology! Workshops are added once they are developed and approved. Please check Upcoming Events as listed on our homepage.

Lee Davis

Lee Davis joined the NAWCC in 1966 and is a Silver Star Fellow. He received the James W. Gibbs Literary Award in 2001 for his many articles, including Supplement no. 18 in 1991, and the Dana J. Blackwell Clock Award in 2003 for excellence in the field of clockmaking. In 1970, he started a business in reverse painting, specializing in early American shelf clock tablets. He has been teaching at the National Watch & Clock Museum and the School of Horology off and on since 1993. Having amassed dozens of photograph, tracings, stencil patterns, and original clock tablets, Lee enjoys sharing this rather unknown art form with others.

Jerry first learned about micro-mechanics and electronics while serving in the US Navy, and these fields became a lifelong passion for him. He has fabricated functional micro-assemblies, including industrial projects and exact-scale model engineering as well as horological projects. His latest build is a watch movement with all of the parts, including the screws, machined individually from bar stock.

Workshop Testimonials  

Review of Introduction to Antique Clocks 1-Day Workshop

I wanted to thank you for putting on a great seminar and training last week. Your teaching style clearly met the needs of the students. I was a little worried before we started about how you could fill up the 8 hours, but the time (pun intended) just flew by. Hope that our schedules allow me to take something else with you. —Joe

Review of Mentorship in Clockmaking

I came from New Mexico, hoping to refine self-taught skills and learn some new ones. The mentorship exceeded my expectations! We learned clock disassembly, cleaning, spring removal, oiling springs, pivot polishing and burnishing on a lathe, inspection, reassembly, lubrication, putting a clock into beat, and regulation. We also visited the museum’s collections area and discussed clockmaking with the NAWCC Executive Director. We used the library to research and date our clocks. These visits were very beneficial to enhancing our knowledge and providing an opportunity to understand and use our NAWCC member benefits. I now have a solid foundation to build upon and add more advanced skills. The mentorship provided the added bonus of making new friends and contacts with similar interests. –Dave

Review of American Style Time/Strike Clock Movements Workshop

I appreciated Ken’s patience and good spirits while guiding me on a journey of understanding how American clocks work. I believe the most important lesson for me was the value of stopping and starting all over again. Thanks! –Kurt

Review of Introduction to Antique Clocks Workshop

The NAWCC’s Introduction to Antique Clocks was an enjoyable course and a worthwhile experience. I especially loved the school’s facilities and the small class size that allowed for plenty of student interaction. This class opened my eyes to so many aspects of time-only clock maintenance, but what impressed me the most was the instructor. Ken’s knowledge and ability to teach allowed me to learn concepts and terminology and then apply it firsthand during our lab assignments. I am so grateful to the NAWCC for offering this course and look forward to attending future classes. –Erich

Review of Lathe Workshop

This course is very worthwhile. Jerry’s focus on achieving a result, and his inventiveness in coming up with solutions and tools to do so, is inspiring. Throughout the class, he offered challenges and examples of ‘outside-of-the-box’ solutions. Being able to run a piece of equipment under skilled guidance, with a chance to make mistakes and figure out solutions, is a much better introduction than any amount of reviews and instructional material. –Kevin
