Maryland Watch Works

Maryland Watch Works is a full service watch facility with a dedication to bring watch making back to the United States, and at McDowell Time we are proud to be the first watch released from their new facility.

Movement Disassembly & Cleaning

Maryland Watch Works will disassemble, inspect, and adjust all parts of the movement mechanism before ultrasonically cleaning the parts in their Tempo 400 cleaning machine. Automatic movements can run for decades as long as they are properly serviced and maintained.

Timing

MWW can test the rate accuracy, amplitude and beat error of mechanical timepiece using the Witschi Watch Expert G4. The G4 has automatic detection of 6 main positions, 4 vertical positions and 2 special positions. A regular overhaul by MWW service watchmakers ensures that your watch functions as perfectly as on the first day you received it.

Water Resistance Maintenance

At MWW your watch will be rigorously tested in a three step process - a vacuum test, a compression test, and a condensation test using the Witschi Proofmaster C Pro pressure and vacucum tester and Rolex* approved water testers (Roxer Natator 125, Roxer Revelator R1 and Diabolic E).

Ultrasonic cleaning

MWW will disassemble the parts of your movement and immerse them in a special solution developed to treat their delicate surface with care. The Tempo 400 cleaning machine thoroughly cleans the movement to help keep it running in top condition.
