For many years I have used 24H time on anything digital that supported that function. For watches I prefer analogue, metal with bracelet and not a strap (they're much easier to clean)
I now work as a paramedic and all our timekeeping is done in 24H... and then I found watchyouseek and found that there 24H analogues out there.
Saved up and finally brought this 2010 AirNautic EarlyBird :D
