Well I can tell you a few things about them. They owned by Grovana which is mostly an OE Swiss maker. Though they also watches under their own name. Though that is rather limited. They may be the actual company that makes that model for Zeno. That or they may even source that case from the same vendor. R/T is also a brand in the field of aircraft instrumentation. The watch portion of that was spun off to Grovana maybe few years ago or so. Also Grovana makes watches for Debaufre. I am quit sure the brand is worth the prices they sell for. They are not well represented in my view at this point in this country. The brand was founded in 1853 so they have been around for awhile.
