The clock is equipped with an automatic movement NH38 as the Pulsar brand also from Seiko, or a product of Seiko.
The black Ziffblatt is less recommendable because in lower light, the silver pointers are not so easy to recognize here, in normal light but it is enough. No luminous material.
Mineral glass is used as a cover glass, but it has not yet scratched. It's not as brilliant as sapphire glass.
The leather strap is high in order, so far, comfortable to wear no signs of disintegration or the like.
Unfortunately, I find no further detailed information about the movement, neither to build nor to manufacture, origin, or frequency. But it seems (under the microscope considered) to be manufactured very precisely.
Now it gets interesting:
The mechanical movement of this clock is since 2 weeks not for a whole minute. I watch it constantly, but I see no deviations ...
If I may compare watches in the same price segment of Citizen: two of them go in my case to approximately two to three minutes per week, which in itself for mechanical watches is indeed a pretty good value.
Maybe I just caught a good specimen; )
