DOM M31 - Cheapest sapphire watch around!
$13.20 NOMOS homage, quartz, very thin.
Sangdo OM311 (40mm Sangdo business watch)

Oh yeah - Megir has some cheap watches (many about $15-$40) in various homage styles. Most are quartz, with Sunon or Miyota movements. They're better than the Currens and really cheap stuff. I'm wearing mine right now.
