FAQs

1. Is this a genuine Hattori part?

Yes, this is a genuine Hattori (Seiko/TMI) part made in Japan. The VX9J and VX9N are multifunction quartz movements produced by Seiko’s Time Module Inc. (TMI) division, featuring three-eye chronograph functions with day at 3, date at 6, and 24-hour at 9 o’clock .

2. What is the function of the hour wheel?

The hour wheel is part of the motion work that drives the hour hand. It receives power from the cannon pinion and turns at a 12:1 reduction ratio, ensuring the hour hand completes one rotation every 12 hours. A worn hour wheel can cause the hour hand to fail to advance correctly or become misaligned with the minute hand.

3. What are the signs that the hour wheel needs replacement?

Common signs include hour hand not advancing correctly, misalignment between hour and minute hands, or visible wear/damage during inspection. A qualified watchmaker can diagnose these issues.
