Welcome to Electronic Instrument Service. We've been servicing horological and ultrasonic cleaning equipment since 1966.

Electronic Instrument Service is the sole factory-authorized US service facility for Greiner-Vibrograf as well as L&R products.

We repair and service all makes and models of watchmakers' cleaning, timeing, dry and wet pressure testers, as well as benchtop ultrasonic cleaners. Some popular models include:

We offer GPS calibration for timeing equipment, and provide a NIST traceable certificate.

Estimates are usually ready within 48 hours of receipt of your equipment. Once you have approved the estimate, turnaround time is typically 3 to 5 business days, except Varamatic and Tempo units, which are 14 to 21 days, subject to parts availability.
