The shortlist is built from Casio automatic listings checked for stock, plus an expert review of the EFK-110D and Casio's own automatic collection page. We weighed movement, case size, water resistance and dial style, and left out anything a listing or source did not support.
Our expert team tests products when it is needed and researches online and in interviews. Every guide is fact-checked and edited by a real person.
