Description

A true rarity is this AS 748, which was released under the Ebauches Trust label, too This movement draws not only attention because of its unusual size, its very small bimetal screw balance or its geneva stripes, but mainly because of its digital time indication.

Direct read watches were not invented in the 1970ies, when they became truely propular, but also before World War II, there were a number of wristwatches with it (and even before that, pocket watches had this kind of indication, too), but such tiny watches were not very usual.

The quality of the direct read mechanism can be seen on the fact, that the change of the hour numbers takes only two short minutes. Only watches with jumping hour are faster there.
