 ORIS Big Crown

The Oris Big Crown was my first mechanical watch purchase. It certainly isn't in the ballpark of a Patek, but is good value for a smaller budget. 
 

 
It is a two tone watch - the case and bracelet are composed of stainless steel with rose gold plating (5 micron).  The crystal is armed-plexi, and it has a mineral crystal skeleton back.  The movement is ORIS 634 (based on ETA 2824-2).
