The Reverso function works smoothly. The case is in great overall condition with just a few light marks commensurate with age, please study the photographs carefully as they are part of the description. The crown is worn and not marked but functions as it should. The rear case has the initials EJS engraved as was normal for the time.
My horologist took the movement out of the case for the photos - there is a dust cover in place and as such the movement can not be seen when in place. This is a picture of the actual movement. There is nice engine turning on the inside of the case. The rear case is stamped Acier Inox, fab suisse and numbered 86460.The watch comes on an original vintage brown leather strap.
