After founding the Mackenroth Watch Company in Northern California, Mr. Mackenroth was awarded a scholarship by the Swiss watch industry to attend the world-famous Centre de Perfectionnement Horloger - WOSTEP, in Neuchâtel, Switzerland. Taught directly by the reknown Antoine Simonin, Mr. Mackenroth's class produced a host of notable talent, including Susan J. Packer, Roy Hovey, John McGonigle and Peter Speake-Marin - the latter two of whom would go on to found their own high-end independent watch brands under their own names

In the ensuing years, the Mackenroth Watch Company became famous for precision watch adjustment, watch restorations of the highest quality and speaking at various events about watches and watch collecting. Mr. Mackenroth was selected to perform a conservation-focused restoration of the original, prototype Lamborghini watch - the very watch presented to Ferrucio Lamborghini by his son Tonino, and which served as the inspiration for the original line of Lamborghini watches.

Today Mr. Mackenroth accepts clients who want to know that their watch was restored correctly; with no corners cut and to the highest standard. He also looks for notable collectables to restore and sell to collectors that want watches that can be used and enjoyed without "surprises" lurking within. He practices his craft in the majestic Western United States.
