A used Hamilton Khaki Field Mechanical sells today for around €400. You paid €625 for it new. Do the subtraction and years of wearing it have cost you a couple of hundred euro, and the watch is still on your wrist and still worth money.
The Khaki Field comes from the field watches Hamilton built for soldiers in the 1940s. The current 38mm version runs on the hand-wound H-50 caliber with an eighty-hour power reserve. You wind it with the crown every morning. There is no battery to die, no app, no firmware, no server that gets switched off in three years. The case is stainless steel. The crystal is sapphire, which shrugs off the scratches that fog a cheaper watch. Any watchmaker on earth can open it and service it by hand. A watch like this keeps time for fifty years and passes to whoever you leave it to.
Set it against the watch most people actually buy. A fashion quartz watch costs around €50. The battery dies inside two years. The mineral crystal scuffs. The style dates. You replace it, and the dead one is worth nothing to anyone. Across twenty years that is roughly five watches and a steady trickle of battery changes, every euro of it gone for good.

A mechanical watch holds its value because the market for it is real. People buy and sell them for decades. Depreciation is what happens to the sealed electronics next to it on the shelf. The Hamilton gives up perhaps a third of its price in the first year and then settles. A serviced example changes hands for €350 to €480 long after the warranty is a memory. Most of that €625 stays with you. It sits in something you wear every day and can sell whenever you want.
The winding is the part owners come to like. Thirty seconds each morning, the same movement for a century, a watch that runs on nothing but your hand. It gathers small marks on the case and a warmth on the strap that a photograph never quite catches. That wear is the object becoming yours.
Verdict: €625 once for a watch you wind by hand, service forever, and sell for €400 when you are done. The fashion watch beside it is €50 you never see again.
