We carefully prepare every custom timepiece before shipping. Delivery estimates are displayed on the product page or at checkout.
An automatic watch is powered by a mechanical movement that winds itself through the natural motion of your wrist. It does not require a battery to operate.
When not worn, an automatic watch may eventually stop and require winding and time adjustment before use. Some ModSphere watches use quartz movements instead; refer to the product's movement specifications.
