Now in College Station, located about 100 miles NNW of Houston and 100 miles east of Austin, Texas. My address is 8709 Greenleaf Drive in Emerald Forest. I am available by appointment only: call (979)704-1113 for repair of mechanical clocks. No house calls. (Click here for a Google map).

Read my essays about clock repair. The best essay is about Pendulum Circular Error and Suspension Springs (updated).


Welcome to Mark Headrick's Horology Page with over 200 pages of clock repair information for antique clock repair and for modern clock repair. It also contains extensive information about clock and watch escapement design and escapements in motion that show the viewer how each escapement is supposed to work. While you are here, you could also visit my websites about genealogy, the Dominican Republic, Antique Cars, the Painted Churches of Texas, the Missions of San Antonio, and others.

My business is antique clock repair. The most well-known clocks in this area are Seth Thomas, Herschede, Howard Miller, Ridgeway, and Sligh clocks. I provide service for all brands of mechanical clocks, including brands that are less well known, such as Atmos, Gustav Becker, Lenzkirsch, Sessions, Waterbury, Gilbert, Ingraham, Smith, Hermle, Schatz, Kundo, Ithaca, Elliott, and Emperor clocks.

The Missions of San Antonio: visit the Spanish missions in San Antonio, Texas. Most tourists visit only the Alamo, missing out on so much of San Antonio's history.

Dinosaurs in Texas: fossils and skeletons, mostly from Texas, including a pterosaur with its forty foot wing span.

The Painted Churches of Texas: visit some of the stunning 19th-century churches with their elaborately decorated interiors, built circa 1840 to 1920 in the area around Schulenburg, Texas, by Czech, Wendish and German immigrants.

Paintings and Art: a fantastic collection of paintings and more art, some dating back to the Middle Ages.

Santo Domingo: a photo gallery showing the Dominican Republic the way I remember it, not the way you see in the tourist books. My family lived there for 27 years. Anyone planning a vacation should consider Santo Domingo as their next destination. As the first European city in America, its historical monuments and history offer so much more than the isolated beach resorts. Forget Punta Cana and Altos de Chavón.

Vintage Car Photo Gallery: Visit my photo gallery of vintage and antique cars with over 200 photos from Dick's Classic Car Museum and the Central Texas Museum of Automotive History.

Social Stratification: Sociology students will be interested to read Dr. Cecil Headrick's thesis, explaining how the American Dream was systematically denied to the majority of Americans. Though Cecil wrote his thesis in 1941, so much of it remains true today!

The Headrick Family tree: Originally from Scotland, William Headrick emigrated to America in 1753. His descendants settled in Greeneville, Tennessee, and then in Winfield, Kansas. I am a twelfth-generation American and a son of the Revolution, with ancestors from Finland, Sweden, Norway, Scotland, England, Ireland, France, Germany, Poland, Turkey, and Austria-Hungary. This genealogy website now has 60 branches with my ancestors. Find your ancestors on Geneanet and Geni to build a website about your family tree.

Jupiter: some photos of Jupiter and the moon above Austin.

Christmas Lights: some photos in Beachy Central Park, College Station.

Compendio Jurídico Dominicano: Estudiantes de la ley dominicana y abogados también pueden leer gratis el compendio del Dr. William C. Headrick, un abogado en Santo Domingo entre 1974 y 2002. Sus otros libros incluyen "Tendencias actuales del derecho francés," "Los derechos humanos en Europa y América," y su última obra en 2008: "Diez años de jurisprudencia civil y comercial (1997-2002)." Su firma fue elegida mejor firma de abogados en la República Dominicana en 2016 y 2022.
