This Datora model 2034 uses the manual wind Valjoux 7734 movement. I bought this NOS in 2007 when Old World Jewelers still had their NOS inventory of 1970's Breitlings. This particular model has a two subdial layout version of the same dial on your watch. The Datora also has a rotating bezel. This watch gets little wrist time I'm afraid so, in honor of your post I'm going to wear it today!
