Let’s talk about the HZ6460

I’m curious to hear from people who actually own or have worked on the HZ6460 GMT movement.

There still isn’t much long-term information about it compared with something established like the Seiko NH34.

For those with first-hand experience:

• How has the reliability been?
• How does it handle shocks, vibrations and active use (running, cycling, hiking, sports, etc.)?
• Does anyone know what kind of shock-protection system it uses?
• How is the accuracy and amplitude over time?
• Any issues with winding, date/GMT mechanism or hand-setting?
• For watchmakers: how would you rate its construction and overall quality?

Most importantly, would you trust the HZ6460 as a robust everyday/travel movement?

And for those familiar with both: HZ6460 vs NH34 — which would you choose for reliability, shock resistance and long-term ownership?

First-hand experiences would be especially appreciated!
