This square 31x40.5mm. stainless steel TISSOT CHRONOMETER is a newer watch produced in very limited numbers (limited edition) and houses a fine 25 jewel automatic chronometer grade TISSOT movement which is visible through the sapphire display back. The black dial with steel Arabic and arrow markers and Dauphine hands evokes the 1950’s era in design. The crown is signed. There are very minor marks on the case from light wear. Comes on a new leather band. This TISSOT watch looks fantastic on the wrist! If you do a google search-these are VERY hard to find.
