A three-day power reserve is the norm. Oris aims for something better.

If you leave a regular automatic watch unworn for a day or two, it will stop. Oris created the Caliber 400 for those who prefer mechanical watches and don't want to wear the same watch every day. The Caliber 400 has a five-day power reserve, so it won't stop even if you leave it unworn for several days. Two barrels, each storing two and a half days' worth of power, provide five days' worth of power.

A watch that you'll want to keep for decades without losing its luster. Oris watches are popular brand watches that are also great gifts for engagements.

It will be the watch you wear once every few days when you feel like making a special moment. At times like these, you can easily change the strap just like you would with clothes thanks to the "Quick Strap Change" function.

The new system allows you to change the bracelet or rubber strap with one touch, without the need for special tools. This saves you from damaging your nails and the hassle of taking your watch to a watchmaker.
