LUMINOX ICE-SAR ARCTIC 1000 SERIES £399

Swat teams, Navy Seals and the Indonesian special forces are all kitted out by Luminox. Why? Because the brand’s always-on, patented light system makes its watches legible at all times of the day – essential if you’re on a time-sensitive operation in challenging conditions. This model, made in collaboration with the Icelandic Association for Search and Rescue (ICE-SAR), is cased in Carbonox, a carbon-based material that’s tough yet lighter than steel. You might not need yours for rescuing stranded souls in frozen wastes, but its pedigree gives it instant big-boy style credentials nonetheless.
