What is worth knowing about a watch with a walk reserve?

Although everyone currently carries a smartphone and can check the time at any time, there is still no shortage of lovers of traditional watchmaking. Among other things, watches with a walk reserve are available. But what does this term actually mean? What is worth knowing when choosing a watch with a walk reserve? In this article I will focus on this very issue.

How does the gait reserve work?

Mechanical watches, in a sense, live in symbiosis with their wearers. All mechanical models, regardless of whether they are equipped with an automatic or manual-winding mechanism, are driven by a mainspring. This spring, located in the barrel, accumulates energy during winding. When the spring is fully wound, it coils tightly, storing energy, which is then gradually released as the spring unwinds. This process provides constant energy to move the wheels, hands, change the date and other functions of the watch.

Gait reserve refers to the amount of time a watch can run from the moment the spring is fully wound until it fully unwinds and the watch stops running. The length of the mainspring has a direct effect on the length of the gait reserve. The longer the spring, the greater the gait reserve, which means the watch can run longer without having to be re-wound. In addition, a longer spring helps reduce vibrations (reducing from 28,800 A/h to 25,200 A/h), which lowers the power demand.

Some men’s and women’s are equipped with two drums and springs, allowing for an even longer gait reserve. Thanks to this solution, timepieces can run for several days without the need for re-winding.

Mechanical manual and automatic watches

Automatic watches use the movement of the wearer’s wrist to drive a balance, which in turn powers a spring. In practice, this means that wearing an automatic watch regularly ensures that the spring is constantly winding. The typical walk reserve in automatic watches is between 36 and 48 hours, although some models, such as those made by Longines, can offer up to 64 hours of walk reserve. This allows the wearer to take the watch off for a day or two, and when put back on, the timepiece will still function without the need to set the time. In the case of the Audemars Piguet The standard is approx. 40-hour walk reserve.

Manual-winding watches, on the other hand, require regular winding with the crown. Although their walk reserve is sometimes slightly longer than that of automatic watches, regular winding is still necessary to ensure continuous operation. The owner of such a watch must remember to wind it regularly to avoid the watch stopping due to the exhaustion of the spring’s energy.

Gait reserve indicators

The gait reserve indicator appears on many models of the brand, for example. Hublot. Watch with such an indicator tells you how much energy is still left in the mainspring. This allows you to monitor how long it will last without the need for re-winding. Many mechanical watches are equipped with a gait reserve indicator, which is not only a practical, but also an aesthetic addition to the dial. This indicator informs the wearer of the amount of remaining energy in the mainspring, allowing the wearer to monitor how long the watch will run without having to be re-wound. The presentation of the gait reserve may vary depending on the model of the watch.

The most common type of indicator is the arrow indicator, which indicates numbers on an arched notch. Other popular forms include linear and “up/down” indicators. Some models offer a colored indicator that changes from blue to red to indicate low energy levels. There are also watches that use “+” and “-” symbols to indicate the spring charge level.

For many watch lovers, the gait reserve indicator is valued not only for its functionality, but also for its elegance and originality of design. Although the timepiece is currently not the only way to keep track of time, there is still no shortage of lovers of the watchmaking tradition.
