Leatherman Tread Tempo Multitool
Leatherman currently offers the Tread, a TSA-friendly multitool you wear around your wrist like a bracelet. This November, it's rolling out the Tread Tempo ($575), which is a Tread multitool with a watch.
The Swiss-made timepiece is water resistant down to 200 meters and comes with burly attachment points, so it won't break off when you're using the screwdrivers, hex drivers, and box wrenches. Buyers will be able to choose from stainless steel or black versions.
