Most watches are created with an average wrist size in mind. For women, that means most metal watches are approximately six inches long and for men they are six and a half inches long. Strap-style bands, weather leather or rubber, tend to run longer with more possibility for adjustment for larger wrists. Stretchable watchbands with elastic allow for a custom fit but may pinch on larger than average wrists. If you are having trouble finding a watchband that fits your larger than average wrist, look for extra long strap bands or order extra links for your watch.
Buy a watch with a larger than average face. The watch can have a metal band or a strap-style band. While you can choose the face style that suits your interest the most, larger faces will look better on a larger wrist, and some longer bands don't fit well with small watch faces. A case that is 35 to 40 millimetres long or larger is a good choice.
Purchase an extra-long strap-style band if the watch you purchased does not have a metal band. Jewelery shops and online sites that specialise in watches and watch accessories should carry a selection of long watch bands. To know which size strap to purchase, wrap a piece of string around your wrist. Measure the length of the string. Subtract the length of the watch case from your measurement. Use the resulting measurement as a guide to buying a new watch strap. Any jeweller can swap out the new strap for the old.
Order additional watch links if your watch has a metal band. Your watch will come with a warranty card or company business card that lists the company's customer service number. Call the company to find out if they sell additional watch links for your watch style. National brands such as Citizen, Seiko and Invicta, as well as most smaller brands, will allow you to order links to add length to your watch. Once the links arrive, take the watch to the store you bought it at to have them added.
Most jewellery and department stores will swap out a new watch band or add links to an existing watchband for free if you purchased the watch there. Don't forget to measure the width of your watchband if you are purchasing a new strap-style band. You will want the width of the old band and the new to match so that the new band fits your watch case. Some brands make watches already fitted with larger bands. This is especially true for sports-style watches. It's worth it to ask your retailer if they carry watches for large wrists.
