How To Guides

Sizing your metal bracelet can be a simple process as long as you have the right tools and a little patience. You’ll need a good small push pin tool to remove the small pins. Follow the steps below to size your bracelet:

  1. Determine the desired fit: Try on the watch and determine how loose or snug you want it to be on your wrist. This will help you decide how many links you need to remove.
  2. Locate and examine the links: Look at the side of your bracelet. The bracelet is made up of links that are the different segments and can be removed. Identify the removable links near the clasp or on the sides of the bracelet. These will have small holes on the side of the links.
  3. Disconnect the links: On the underside of the bracelet link, you'll find small arrows indicating the direction to push the pin out. Set the pin tool in the hole to push out the pins in the indicated direction. Apply gentle pressure until the pin pops out. Be careful not to force it or damage the bracelet. It may help to use a small pair of pliers to then pull the pin out from the other size
  4. Remove the links: Once the pin is released, you can separate the desired link(s) from the rest of the bracelet. It is recommended to remove equal links from either side of the clasp, if possible, to keep the clasp centered under your wrist when worn.
  5. Reconnect the bracelet: After removing the necessary links, reattach the bracelet by aligning the remaining links and inserting the pin back into place. Use the tool to push it in until it's secure. It may help to use a small jewellery hammer.
  6. Test the fit: Try on the watch again to ensure it fits comfortably. If it's too loose or tight, repeat the process to remove or add additional links until you achieve the desired fit.

Remember, if you're unsure about sizing the watch bracelet yourself, it's always recommended to visit a professional jeweler or watch specialist who can assist you in getting the perfect fit. If you haven’t ordered your watch yet, you can also request the bracelet be sized before shipping. This is a service we offer our customers free of charge.

Automatic watches are powered by the natural motion of the wearer's wrist or by manual winding the crown. Here's a quick guide on how to power your automatic watch using both methods:

1. Powering by Motion:

  • Make sure the watch is safely fastened to your wrist.
  • As you move your arm throughout the day, the motion of your wrist will rotate the rotor inside the watch, in turn winding the mainspring, which powers your watch.
  • Regular wear for active individuals, often provides sufficient motion to keep the watch running.
  • If you have a day that’s less active, you can gentle shake your arm back and forth to provide your watch with enough motion to keep it ticking.

2. Powering by Manual Winding:

  • Locate the crown which is found at the 3 o’clock position on all Cestrian watches.
  • Gently unscrew the crown by turning it anti-clockwise.
  • Once it’s unscrewed, you will be able to rotate it clockwise to manually wind the mainspring to power your watch.
  • We recommend gently rotating the crown approximately 30-40 full rotations. Avoid rotating the crown more than this and if you feel any resistance, stop and do not force it.
  • Once wound, push the crown down and rotate it clockwise to screw it back down to its original positions. Its very important to carefully screw your crown all the way back in to ensure the watch maintains its water-resistance rating.

All Cestrian watches have a power reserve of 41 hours.
If the watch is fully wound and then worn daily, it should continue to operate without needing any additional winding. However, if it doesnt' receive much movement or isn’t worn for a few days, manual winding may be needed to initiate the movement and get your watch moving again.


Automatic watches are amazing timepieces that don't require much maintenance. However, sometimes problems may arise. Don't worry, though! If you think your watch may have an issue, check out our Troubleshooting Guides.
