Unitas 540
Description
The form caliber Unitar 540 is an extraordinary movement in terms of features and workmanship.
Despite the small size, it contains an direct driven center second hand and a beautiful and technical useful, since it is temperature resistant, gold-toned Glucycur screw balance, which is shock protected by an Incabloc System on the top and by an unknown system on the dial plate.
