    The finely silver-plated dial at first reveals nothing of the exquisite movement inside the Patria. Reserved and elegant, it displays the hours, minutes, and seconds, the latter within an unusually large, off-center scaled circle. The connoisseur, however, suspects the remarkable technology hidden behind the perfect, hand-finished hands.

    More than 100 years ago, aficionados already praised the virtuosity of Glashütte’s watchmakers. In the Patria, these traditions have now been revived to set new standards in the upper price segment.

    According to vintage tradition, the bearing bores for the gear train bearings are placed underneath a large base plate that spans almost the entire diameter of the movement. Its surface has been embellished with fine finishing and engraving, just as the area around the balance, balance cock, and escapement have been lovingly finished. Screw-mounted gold chatons that have been set into the three-quarter-plate and the decoration of the crown and ratchet wheels with an iridescent sunburst decoration constitute further highlights.

    Through the sapphire crystal case back, one has an unimpeded view of the two steel winding wheels and the special click with its graceful steel spring. The heads of all screws have been polished according to vintage company tradition.

    The skeletonized and finely finished balance cock allows a free view of Tutima’s own oscillating system. The balance wheel outfitted with weighted regulating screws oscillates at a frequency of 21,600 vph and contains a Breguet hairspring with a special terminal curve – a detailed element completed by hand that adds honor to even such a noble tradition as that of Glashütte
