The International Durowe 7527-3 watch movement, which was used during the period of 1975-1976, belongs to the last MST designed family. It features a hacking mechanism enabled by stopping the 4th wheel, and its balance is less commonly interrupted. The indirect minute drive allows for a large balance and a low-profile design. Additionally, an optional excenter device can be mounted on the regulator. The movement includes a rotor with a bayonet joint and a right-handed crown-wheel screw. Furthermore, it offers various functions such as automatic winding, a sweep second hand, day and date display, and a stop seconds function. The day can be set by adjusting the time between 20:30-1:15h, while the date has a quickset feature.
