Owning a timepiece can be a complicated affair. You should think of your duties as the owner of a chronograph, field or dive watch in the same way you do automobile ownership, or a relationship: some TLC is required. There will be strap changes — many of them. Batteries will need to be replaced, scratches buffed, bracelet links added, removed and added yet again. What would your Instagram followers say if they knew your timepiece was haphazardly strewn on a bedside table every night where the cat could knock it to the hardwood? #careless. It needs to be properly housed and, if it’s powered by a self-winding movement, wouldn’t it be nice to strap it up fully charged each and every morning? Here are the tools you need to keep that special timepiece in tip-top shape, so you can hand it down to junior one day with just the right amount of patina.
