Free Strap Adjustment
It's important that your watch fits your wrist comfortably and looks great at the same time.
Leather strap watches tend to fit without a problem for most wearers. However, watches fitted with metal bracelets often need adjusting to get the perfect fit.
This is generally a very simple procedure. We can do this for you, or you can get the watch adjusted locally.
Option 1. Specify your wrist measurement and we will adjust it before being sent
When purchasing a watch which has a metal bracelet with adjustable links, we will gladly adjust the watch bracelet to fit your wrist before sending the watch to you - free of charge!
Simply type your wrist measurement (in inches or centimetres) into the bracelet size section of the checkout and we will ensure the watch bracelet is adjusted accordingly before being sent to you. We will include all the surplus links, with the watch.
How to measure your wrist
You can measure your wrist with a piece of string which you can measure against a ruler:

You should allow about half a centimetre (1/4 inch) of slack to prevent it being too tight on your wrist.
In the event of you needing an extra-long wrist bracelet, which requires an extension to the original watch, we must obtain extra links from the manufacturer, and in this event, we will contact you to inform you of any possible delays or applicable charges.
Watches with bracelets adjusted by WatchNation are still eligible under our refund policy.
Option 2. Buy the watch online from WatchNation and have it adjusted locally
If you wish, you can have it adjusted locally by another jeweller or key cutter. However, you will have to cover the cost of this option yourself.
