Dear HAQ friends,

I wonder why there few or no grand Seiko 9F quartz models with colorful dials compared to, for example, the grand Seiko spring drive models?
Technologically, a quartz movement without solar should not imply any restrictions.
I am thinking here, for example, of spring drive models such as SLGA019 or SBGH351.

At least that's how it seems to me in Germany, perhaps the range is different in other countries.

Thanks a lot for any answers!

Hello together,

As far as I know 32 kHz tuning fork quartz have a not negligible position dependency.
As I understand the situation, the temperature dependence is compensated for HAQ, but not the position dependency.

I now had the idea that the rate deviation can be counteracted/minimized by placing the watch in a certain position when not worn.
For example, there could be a position in which the watch runs a little slower than usual. If the watch has a tendency to run slightly fast, this…
