    Sur sa partie médiane, ce verre est muni d'une  partie saillante 2 de pourtour     c@-lindrique.     Dans cette partie est logé, à frottement doux,  un cercle métallique 3 à l'intérieur duquel  est forcé le cadran 4 d'une boussole dont 5  désigne l'aiguille aimantée. Un fond métal  lique 6 est forcé, par le contour extérieur  d'une nervure circulaire 7, à. l'intérieur de la  base du cercle 3.    d'une collerette périphérique 11. M intérieur de  ce cercle est forcé le cadran 1? d'une boussole  dont 13 désigne     l'aiguille    aimantée. Sur une  partie du cercle 10 dépassant le niveau du  cadran 8 est forcée une lunette 15 dans la  quelle est montée une glace 16.

In this part is housed, with gentle friction, a metal circle 3 inside which is forced the dial 4 of a compass of which 5 designates the magnetic needle. A lique metal bottom 6 is forced, by the outer contour of a circular rib 7, to. the inside of the base of the circle 3. of a peripheral flange 11. M inside this circle is the dial 1 forced? a compass of which 13 designates the magnetic needle. On a part of the circle 10 exceeding the level of the dial 8 is forced a bezel 15 in which is mounted a crystal 16.

   Circle 10 is. engaged by the outer contour of its base, in a cylindrical rib 17 of a bottom 18, itself forced into the opening 9 of the lens 8.
