Like so many other watches created at schools, this is a technically and optically supreme piece: a wristwatch with a high quality movement decorated with Geneva stripe design and an incredibly appealing silvered dial with delicately shimmering subsidiary dials, a blue analog date, windows for the day of the week and the month in French, as well as a moon phase display, complemented by yellow gold accents. It is fitted with the manual wind calibre Valjoux 88, which is a modification of the legendary Valjoux 72C.
