This is a Stainless Steel cased Chronograph, which appears to be a variant of the Dual Date II model,  42 mm to tip of crown, with a high quality, non-signature, padded black leather, white edge stitched band with stainless steel deployment  clasp. This watch is manufactured in Switzerland by Dubey & Schaldenbrand, a relatively new (post WWII in 1946) but world renown manufacturer of high end luxury dress and sport watches. The face is simple and easy to read, featuring a black dial with white luminescent hands and white arabic numeral marks. There is a fixed coined edge bezel, also in stainless steel. The Dial features two sub-registers, the upper one a 24 hr. dial, and the lower one a 12 hr. accumulating register. There is red, center-mounted seconds accumulating hand as part of the chrono function. There is a date window at the 6 o'clock position.The back bezel features the words "Dubey & Schaldenbrand", "Automatique", and "Swiss Made, Stainless Steel". The crystal and dial are without flaw. The lugs are 18 mm wide. This watch was cleaned and serviced approximately two years ago, and is in very good condition, keeps good time, and has been worn only a few times since. Round chrono pushers function as they are supposed to, and movement is running well. Crown is fluted edge and approx. 6 mm in dia. Comes with signature leather pouch, and a German language quick summary operating manual as well as a guarantee form which does not show any dealer's stamp or date of purchase. Free expedited shipping. Guaranteed authentic.
