Unitas 540


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.
