Why is a watch winder's Turn-and-Rest function important?Įqually important to consider is the "combination effective turns achieved" by combining the rest and turn programming motion such as our winders would. However, it is always advisable to use the least numbers of turns to wind up a watch if possible so that over-stressing or excessive wear and tear of the watch mechanism can be eliminated. And a watch doesn't need to be always wound up 100%. (b) Or an office worker who doesn't move his arm as often as the sport person (and thus result in a lower TPD) Īs long as there are sufficient arm movements (not non-stop movements) throughout the day, the movements will be converted into energy stored in the watch's main spring and keeps the watch running effectively. (a) One is would an active sport enthusiast (with frequent arm movement would provide a higher TPD) will have their Rolex fully wound up at the end of the day To put it into perspective, let say the same model of Rolex (or any other brand) is being worn by two different types of person: In reality, there is no real hard TPD a watch must strictly adhere to. TPD is more meaningful as a way to compare different watch movements' efficiency to wind up a watch.
However, different designs of watches require different numbers of turns to wind fully. But of course, a watch should not be wound up non-stop, as per aforementioned and a watch needs not to be 100% fully wound up all the time. Technically, what TPD actually means is: "the static minimum numbers of turns to fully wind up a watch from zero to 100% if the watch is being wound up non-stop in a vertical plane".
"TPD" or Turns Per Day should only be viewed as a rough guideline. What is TPD (Turns per Day)? Do all watches need to be 100% wound all of the time?
