There is usually a logical explanation. If the weather is warm, you don't wear your dressing gown in the morning when you first get up, and if - a couple of weeks ago - you left your vintage Heuer in your dressing gown pocket it will seem as if your vintage Heuer is lost.

Meanwhile, unknowingly, you have been walking past your lost vintage Heuer two or three times a day, as you pass your dressing gown hanging peacefully on its hook.

Lots of work searching for nothing, chance found the watch.
