Speaking of mechanical watches, what do you think of Hamilton watches? I think they have an Swiss ETA movement but are put together in China and are originaly designed in the US and were issued during WWII. They also have a hand wound mechanical field watch at a very affordable price and they have sapphire crystals as a bonus. What do you think about a hand wound watch in a survival situation, would you think about winding it? Anyway they have a big crown so that the pilots could wind them with gloves on I guess... They also have automatic movements (with a rotor like the Rolex). In about the same range there's Glycine Combat watches. The point is that military mechanical watches look interesting.
