HOW TO TAKE CARE OF YOUR WATCH

Most watches have some level of water resistance. If your watch isn’t water resistant, it may be able to handle small splashes, but don’t risk it. If it has a leather band, don’t get it wet.

How to clean your watch case

  • Do not move the crown or push any buttons when your watch is in contact with water, as this may let water enter the case.
  • If your watch is not water resistant, dip a cotton swab in a bowl of warm water with a drop or two of soap in. Squeeze the tip of the cotton swab to remove most of the water and gently rub the case.
  • If your watch is water resistant, soak a soft cloth in a bowl of warm water with two drops of mild washing-up liquid added. Wring most of the water out of the cloth and gently rub the case with it.

How to clean your leather watch strap

As a rule of thumb, genuine leather shouldn’t get wet. This includes sweat and the moisture that evaporates from your body throughout the day, which is why we recommend you don’t wear your leather-strapped watch every day and always take it off when you go to sleep. 1. If you must clean your leather strap, remove it from the case and rub it down with a clean, dry cloth. 2. Apply leather cleaner and conditioner with a soft cloth, gently massaging the lotion into the leather. 3. Finish by wiping with a clean cloth to prevent staining and let the straps air-dry overnight.

Don’t wear it so tight that you have to bend the strap backwards to unbuckle your watch, as this can permanently deform the leather.

How to care for your watch

  • Store your watch in a dark, dry place to avoid corrosion and discolouration of the dial.
  • Always replace the battery on a quartz watch as soon as it runs out. With time, an empty battery may start leaking, damaging the watch’s movement.
  • Run mechanical watches at least two days a year to prevent gears and cogs from sticking.
  • You should always get your watch serviced by a professional every 3 years.

GENERAL CARE

Rule of thumb: Make sure your watch is the last thing you put on and the first thing you take off.

  • Take your watch off and store it safely before engaging in any activity that could damage it.
  • Take it off before engaging in any activity likely to make you sweat.
  • Take it off before you shower, bathe, or go for a swim.
  • Take it off before cooking or cleaning.
  • Take it off before you go to bed.
  • Don’t expose your watch to chemicals such as cologne, sunscreen, perfume, chlorine, hair gel, etc., as these can discolour, stain, or dull surfaces.
  • Try to store your watch separately in a soft enclosure to prevent scratching and rubbing.
  • If your watch has closures or clasps, close these to prevent tangling.
  • Keep your watch stored in a dry, dark place, and avoid heat fluctuation.

How To Remove A Watch Strap & Replace With A New One

To remove and change your watch strap, you’ll need:

  • The watch
  • A replacement strap
  • A soft surface such as a cloth, t-shirt or mouse pad

You may also need:

  • A spring bar tool
  • Or a sharp pointed object

HOW TO REMOVE A WATCH STRAP

  1. Place your watch on a soft surface. This prevents it from getting scratched or damaged.

  2. If your watch has quick-release pins on the underside, push the small lever inward to release the strap.

  1. If your watch has drilled lugs – small holes in the lugs extending from the main watch case – use a sharp, pointed object to push the spring bar in and release the strap. Be careful that the spring bar doesn't slide out of the strap and get lost.
  1. If your watch strap has neither of these, use a spring bar tool. This is a small tool with a v-shaped tip. Use it to compress the spring bar from the underside of the strap between the lugs on the right. Using the tool, push down the ridge of the spring bar to release the strap.

HOW TO REPLACE A WATCH STRAP

First, check the lug width of your new watch to verify that it's 20 mm. You can find all our watch straps here. Using the filters, select only the matching width to see our selection for your watch.

If your replacement strap has quick-release bars, press the bar inward and slot it into place between the lugs. You’ll feel it ‘lock’ into position.

If your new strap doesn’t have quick-release pins, use the spring bar tool again. Place one end of the pin into place, then use the tool to compress the spring bar as you slot it in place. You’ll feel it ‘lock’ in position.

Remember to take your time and be careful not to scratch the lugs or damage the new watch strap.
