...and what it is, is a $30 Chinese automatic Breitling Navitimer "homage".  It looks very nice, and so far it keeps perfect time. It feels about as water resistant as a burlap sack, so i wouldn't get it wet if i could help it. The band is also very nice looking, although neither it nor the watch case are stainless steel, even though the case back clearly says "ALL STAINLESS STEEL". (Maybe the case back is all stainless, but I promise you that the rest is chrome-plated.) but It's a $30 mechanical watch, do you care?

The slide rule is reasonably accurate. There is no chronograph feature. The dial glass is convex and straight-up glass, so don't bang this thing around.

Other than that, there isn't much to say. it looks exactly as pictured. It's very attractive and it tells time. Shipping was fast, arriving a full 9 days before the estimated shipping window. I'm sure i just lucked out with customs, but that's still impressive for Chinese air-mail.

So once again, for what this is, it is awesome. But be sure you're aware of what you're buying, and adjust your expectations accordingly. If you want a solid, dependable, all stainless-steel, water-resistant, good looking aviator-style watch with an accurate slide rule and a chronograph, then shell out the $ for a Casio, Seiko, or Rotary. (I would have said "Or a Breitling", but seriously, if you could afford that, you wouldn't be here looking at this thing anyway.) If you just want a neat, cheap Chinese automatic Breitling Navitimer homage, then this is your stop.
