I can't find any information about this watch brand, except for a few mentions of cheap $10 ones but I can't imagine one like this falls into that category.
Here's the mechanism. The bracelet is very comfortable to wear. Although it looks like rust, it isn't. I've just cleaned it off with a cloth.
Perfectly fine watch from an obscure brand. Not much financial value, unfortunately. Felsa cal 1560 movement.
Here's about the movement: Felsa 1560 As for the watch there were any number of marketers that would have a perfectly serviceable movement placed in a nice enough case and sold through some unique channel; a "house brand" if you will. Nice enough watch but certainly not a known brand. Retailers like to sell merchandise that can't be price shopped and they can use terms like "exclusive". The bracelet looks like a Forstner Komfit. I'm a fan of those.
The Felsa 1560 was used by literally hundreds of watch brands, from well known houses like RADO to your Realm. They were produced in varying quantities, from hundreds to hundreds of thousands by various marketers. Trying to find information on these lesser known brands is a needle in a haystack task.
