Possibly an unpopular answer but the Swatch Sistem 51 power reserve is extremely good. I think it lasts over 70 hours idle.

Mind a question?

Why?

This is a pretty ordinary watch. There are loads of all-black watches with chunky, tactical silhouettes.

So like, is this your friend and he lost the watch and you’re trying to help? Is this someone famous? Just curious. Sometimes these questions are like, what watch is this famous guy wearing? or wow what’s the deal with this very cool, unusual watch? And maybe it’s just the photo, but I’m kinda like, yeah, looks like a black watch.
