The Unitas 6325 is a truely nice large men's movement with a diameter of 13 lignes, which is very flat and thus does not have a shock protection for the large and light nickel balance. It impresses visually by its red-golden tone.
In this movement, 21 jewels are used, four of them as deck jewels, which help achieving good precision results.
Other versions only offered 17 jewels, but contained a pair of Incabloc shock protections.
The Unitas 6325 is a late bloomer and was probably made in the 1960ies. It already uses the modern beating rate of 21600A/h and the modern shape of the nickel balance, which is used until today, but on the other hand, the seconds are displayed on a subseconds display at "6" like on vintage watches.
