Jahn Jocksan –
The listed power-reserve specification is another detail I paid attention to because I prefer knowing what the movement specification is. I spent some time going through the details before settling on this model. The item arrived in good condition, and the first look matched the listed configuration. Nothing about the configuration feels out of place.
