When I am in paramedic service ...
... which I have to explain with a few words: In Austria, initial and basic life support, retrieval and transport is offered by professional as well as voluntary personnel with a training that is less elaborate and long than the paramedic training in the US. But we have more than 70,000 voluntary "paramedics" (Rettungssanitäter) in the small country of Austria.
Well, back to watches: Since I have to expect to come into contact with germs or patients' body fluids, I only take watches with smooth rubber straps. Absolutely no steel or titanium bracelets, since all those links have too many holes, gaps and edges and collect germs. Disinfectants are expensive - and now even rare - , so there is no way to completely submerge the whole watch in disinfectant fluid, especially not several times per shift. So I need a watch that can be easily wiped off with special disinfectant wipes. The best one in this respect is the PuristSPro Rescue watch. It also comes handy for quick-measuring the pulse (but I do not use the scales, the numbers are far too tiny).
As an alternative, I have a Tudor Pelagos LHD, again with a smooth aftermarket rubber strap. The original rubber strap that comes with the watch has too many edges and is too difficult to be cleaned effectively.
