Place your watch crown side down on your night stand or dresser. You are less likely to scratch the side of your valuable watch with only the crown making contact with the surface.
Invest in Deployant Clasps for Your Watch Straps or Bands
Your watch strap will last 4-5 times longer if you use a deployant clasp to take it on and off. With a standard buckle, you must pull back on the strap to put it on and off. This daily pulling back wears (creases) the strap out around the buckle. With at deployant clasp you avoid this. And, it is easier to use and safer (you can't accidentally slip and drop your watch putting it on). A deployant clasp works much the same way as a bracelet does.
Store Your Watch Collection in a Watch Box
Rather than keeping your growing watch collection loosely arranged in your dresser drawer, invest in a good watch box that keeps your watches safe from scratches and nicely displayed. If you have some XXL or large dial watches store them on the end slots or skip a slot to keep the crown from banging into another watch in the box.
Rotate Your Watches and/or Invest in a Good Watch Winder
With self-winding and hand wound watches it is important to keep them running by rotating your watches. If a watch sits unworn, for a long period of time, the lubricant and clump up or pool and doesn't get evenly distributed. A watch winder can help keep your self-winding watches in good condition. For hand wound watches, wind them frequently to keep them running at their best.
Salt Water and Your Dive Watch
