This invention thus has as its purpose to provide in a timepiece having a mechanical analog display, connection means between the electronic module and the electro-acoustic transducer, such means being defined by the claims. U.S. Pat. No. 2,245,129 describes a batchwise two-step preparation of polycaprolactam from.omega.-aminocapronitrile ("ACN") and water at a temperature within the range from 150 to 300.degree. C., governed by a specific temperature program as a function of the amount of water added, and a pressure of not more than 30 bar. The disadvantages of this process are the long reaction times (20 h in step 1), the low viscosity of the resulting polycaproplactam and the high level of volatile bases (essentially primary acid amides) compared with a polycaprolactam prepared from caprolactam.
DE-C 35 34 817, U.S. Pat. Nos. 4,568,736 and 4,629,776 partly solve the problems described in U.S. Pat. No. 2,245,129 by the use of phosphorus- and sulfur-containing catalysts. The use of the catalysts mentioned improves the low space-time yield of the process described in U.S. Pat. No. 2,245,129. However, the level of volatile bases in all the products prepared by the abovementioned processes is still too high, so that the polyamides are difficult to process and have a reduced carboxyl end group number. The stoichiometric discrepancy between the amino and carboxyl end groups in the products of the abovementioned processes is responsible for their showing an insufficient degree of polymerization and a slow increase in molecular weight during tempering. Furthermore, complete removal of the catalysts is virtually impossible, so that the chemical and physical behavior of the polymers prepared using the catalysts, such as type and quantity of end groups or snap-off behavior during spinning, is adversely affected.
EP-A 479 306 proposes, in relation to the reaction of ACN with water to give polycaprolactam, to remove ammonia and water continuously, by decompressing, once a reaction temperature from 200 to 260.degree. C. has been attained and at the same time to add water continuously while selecting a pressure within the range from 14 to 24.times.10.
