Aqui tienes la respuesta de Meistersinger :
En pocas palabras : la decoracion y el trabajo sobre el movimiento + el acabado del reloj son las diferencias entre el edicion 1Z y los demas.
The Scrypto 1Z Edition is being manufactured in a liwithed edition of 222 watches. The large dial is made in one of the few workshops in the Swiss Jura region which still masters the manufacture of fine enamel dials. This dial is fabricated entirely by hand, in more than 30 individual steps.
Its delicate blue 'Edition 1Z' logo reflects the color of the blued hand. The Unitas 6497 movement, used in the past for pocket watches only, has been refined. It is now fitted with a Glycudur screw balance wheel, swan-neck fine adjustment, blued screws and Geneva stripes; the ratchet wheel is engraved. The large rear glass and the crowned crystal, 2.2 mm
thick, are made of sapphire glass. Crocodile leather straps and the Meistersinger butterfly clasp complete the picture. The knurled wood presentation box and the certificate underscore the exclusive character of the Edition 1Z.
