Abstract
The compass is composed of a glass plate constituting a transparent outer component and of a thin plate constituting an inner transparent component. Two bearings are fixed in holes in these plates, one bearing being situated near the upper face and covered by a disk. An arbor can thus be machined with a maximum length and can support the compass needle with the greatest possible precision. The compass unit, comprising a setting ring which holds the two plates in place, may be driven with a gasket into the radial wall of the case body in lieu of the usual watch glass.
