The wristwatch - A supplemental tool for determining time of death

Abstract

Estimation of the time of death (TOD) is a central task to forensic pathologists. The current gold standard method for TOD-estimation is only applicable in the first 24 h post-mortem and it is advisable to employ multiple methods, if possible. A wristwatch found on the decedent can be a valuable additional tool for TOD-estimation. This technical report provides a brief overview of the two major watch types - mechanical and quartz-based timepieces - and a step-by-step guide to using these for TOD-estimation. The methods are demonstrated using case illustrations.
