In terms of technical development,
this timepiece has all the
essential attributes which
established ZRC’s reputation
and which provide its water resistance. Firstly, the Crown Protection
SystemTM guarantees the safety of the crown by preventing the
strap with retractable lugs from being repositioned if the crown
is not fully screwed down. Secondly, the ECSTM (Easy Clean
System) ensures the inside of the unidirectional rotating bezel is
clean by diluting and removing sea salt, which when crystallized
can irreparably damage a diving watch.
