Avoirdupois was founded in 2017 by James Stumpf in the Hudson Square neighborhood in the borough of Manhattan to create a new legacy of not just New York manufacturing - but American manufacturing.

Housing CNC Machining, Turning, Precision Grinding, Electrical Discharge Machining, CMM, Vision Inspection, Roundness measurement, Finishing, Assembly and everything in-between - we operation a vertically-integrated facility.

We've focused all of our efforts in design, engineering and precision manufacturing over the past five years to create what we feel is a compelling mechanical wristwatch.
