Bucherer Automatic Chronograph
most likely a 2892 with a Dubuis-Depraz chronograph module

The Bucherer reference number 283.500
does not reveal the make of the movement inside. What is however quite remarkable, is the fact that this watch has a snap-on case back. Another way to shave some cents off the manufacturing price. Bucherer was often able to offer watches with similar features and movements at a lower price then established brands. Of course this has changed today with the introduction of the "CARL F. BUCHERER" brand. And during my last trip to Switzerland Xmas 2008, I noticed that Bucherer in fact decided to "kill" it's old "Bucherer" brand. The idea is probably not to cannibalize the newer and much more expensive "CARL F. BUCHERER" brand.
