These type of watches are really special... it's a Postala Chronograph and very similar to the Unver Disco Volante which is also on the site! The 12 hour bezel is also super special (seen on some mega rare Omega 33.3's) which makes for the absence of the hour markers on the dial! The original dial is super nice, copper/salmon color with three color print and Telemeter and Tachymeter scales. The steel/chrome case measures 37,5mm excl. crown. Movement is the Landeron 39 which is very clean and just serviced. Attached is a period style stretch bracelet. This watch is really stunningly beautiful and very affordable with great wrist presence.
