OUR STORY

Experience at
the workbench.

The watchmaking story began in Chicago, where Robert Schierer, Elmer Schierer, and Frank Popp opened Schierer and Popp Jewelers in 1955. Lorenzo and Donna Calderon carried on the work for more than 30 years.

Today the tradition continues in St. Thomas with On Time Watch Repair, established in 2015 by their son Robert Calderon. We appreciate the trust our community places in us and the timepieces you bring to our bench.
