Up for sale is a working Seiko QT-2100 quartz tester, built by Fuji. This is the flagship quartz tester from Seiko from the late 70s. See the photos for specifications and condition. The unit is working fine. Included in the sale with the main unit will be the electromagnetic microphone (for analog or digital quartz watches) and power cord.

This unit is capable of testing Seiko 94xx & 99xx series movements with twin-quartz oscillators. It has a printer output connector but a printer is not included in the sale. It is also capable of measuring mechanical watches but requires an acoustic microphone for that, also not included in the sale.

If you would like a PDF of the instruction manual, send me a message.

Known issues:

1. The dot matrix auxiliary display has a "cloudy" section mainly in the center. It's hard to read there, but you can read the characters. You can see this in the photos. But the main LED display is working perfectly.

2. The microphone input selector pushbutton gets a little sticky. Cycling it a few times takes care of it.

3. The STEP/LC selector switch, actually the same type of switch as the input selector, has the same issue and cycling it takes care of it as well.

Thanks for looking and thanks to the admins.
