Nixon 40mm Watch FAQs

40mm watches are considered to be medium size watches. For most wrists, 40mm watches will be a great fit. You can visit our watch size guide to see photographs that help demonstrate how the different watch sizes look on different wrists.
None of our watches are fully waterproof, but each one carries a water rating indicating how much water exposure it can handle. Most Nixon watches carry a 10 ATM rating, meaning they can handle everyday water contact such as swimming, showering, and washing dishes. A lower ATM rating means less water protection, while a higher ATM rating means more.
There is no single replacement band size that will fit a 40mm watch. The 40mm size refers to the watch case itself. If you are looking to replace a watch strap, you must find your watch lug width. Match this size to the size of the replacement watch band.
