6 FAQs about [Movement with power storage of more than 70 hours]
How long is a power reserve?
The capability and length of the power reserve have always been something that most watch brands have worked to improve. Today, most automatic watches have a power reserve of 38-50 hours, but there are those with both shorter and longer reserves.
How long does the power reserve last on a watch?
The mainspring gets wound up, then as the watch runs down (displaying the time), it eventually stops when all of the tension (stored energy) is released from the spring. Until recently, the most common length of power reserve was around ~38 hours (an ETA 2824-2 for example) or 46 hours (an ETA/Unitas 6497-1).
Do ultra-long power reserve watches keep resetting the time?
You won’t have to keep resetting the time if you have an ultra-long power reserve watch. A watch’s power reserve can be an overlooked function when buying a watch, but it’s important if you wear multiple watches. When a watch’s power reserve runs down, the watch stops keeping time, and you need to reset it.
How long should a mainspring power reserve be?
Until recently, the most common length of power reserve was around ~38 hours (an ETA 2824-2 for example) or 46 hours (an ETA/Unitas 6497-1). With advances in materials and design of mainsprings and mainspring barrels, it has become a trend to increase the power reserve as much as possible.
What is a power reserve?
Power Reserve refers to the running time of a fully wound mechanical watch (manual-wind or automatic). For example, if you fully wind your watch and place it on your dresser, how long before it stops running and needs to be wound again - that is the power reserve.
How long can you leave a watch without a power reserve?
The longer the power reserve, the longer you can leave your watch between wearing or winding – regardless of how much power reserve is left when you leave it. How much PR you “need” depends on a) whether you give a damn and b) your watch wearing habits. Generally speaking, most mechanical watches have a power reserve between 40 and 50 hours.
