What we do

The founders, Mark & Theresa Heist, began their present careers at Breitling shortly after the opening of the US headquarters for distribution and service. As brand awareness developed more and more of the older timepieces came in for service. Recognizing the need to preserve and maintain the vintage timepieces we started providing this specialized service in 1992 while still working for Breitling USA. Our independent operation began in 1994 as the demand for service, repair and restoration of these vintage mechanical timepieces grew and ultimately adopted the name Horological Services.

To date we have seen as many as 400 of these vintage mechanical, mostly chronograph, timepieces each year. This has become our specialty. We also service, repair or restore other vintage chronographs, pocket watches, vintage and antique watches, aircraft clocks and other high-grade clocks. 

To accomplish this work we built and equipped our facility to provide precision turning, boring, drilling and measuring using lathes, drills, jig borer, microscopes and an optical comparator. A laser welder allows us to handle all repairs to the watch case. 

We are best known for our vintage Breitling chronograph work with an onsite spare parts inventory and the ability to fabricate damaged or missing components, often to original equipment manufacturer's specifications.
