    The present stop-watch is held within a spring-loaded aluminium support. It is understood that the purpose of this construction was twofold, namely to protect the mechanical movement from deregulation by the vibrations of the vessel but also from strong electro-magnetic fields adversely affecting the precision. Aluminium's inability to transmit electricity and the particular construction based on the principle of the Faraday cage represented the best possible solution available.
