This rare and very nice Swiss made Olma hand wound Chronograph was made around 1955, is in very good shape and running well! Gold plated case with steel screw back. This Olma has a diameter of 35 mm, measured from left to right without the crown and pushers. The watch is 13 mm thick. NOS 18 mm brown "Crocodile Veritable" strap with gold plated buckle; length of watch + strap is 22.5 cm. Movement: hand wound Swiss made Landeron 48 chronograph movement with 17 jewels and incabloc. The pusher at the "2" is start; the pusher at the four is stop and reset. The small subdial at the "9" is the always moving second hand; the central second hand is for the chronograph and the subdial at the "3" is the chronograph minute counter. The movement runs very well; the chronograph also works fine and returns perfectly to zero. Comes with the original Olma box. Will be packaged very well and shipped by registered and insured mail.
