This diving watch is an appropriate choice for Simu Liu's character in the film. Liu plays rescue diver David Yuasa.

Last Breath is based on a real diving accident in 2012, when diver Chris Lemons had his umbilical cable severed and became trapped around 100 metres (330 ft) under the sea without heat or light, and with only the small amount of breathing gas in his backup tank.

The movie also stars Woody Harrelson as Duncan Allcock and Finn Cole as Chris Lemons and Cliff Curtis as Captain Andre Jenson.
