Keyless works are a type of watch movement that does not require a traditional key to wind or set the time. Instead, they use a small lever or button to release the tension on the mainspring, allowing the watch to be wound or set. This makes them much more convenient to use than traditional key-wound watches. The NH35 is a popular keyless watch movement that is used in a wide variety of watches.
There are several benefits to using a keyless watch movement. First, they are much more convenient to use than traditional key-wound watches. Second, they are less likely to be damaged, as there is no key to lose or break. Third, they are more accurate, as the tension on the mainspring is always consistent.
