What is TPD with a Watch Winder?
What does 'TPD' mean?
‘TPD’ is an abbreviation for 'Turns Per Day'.
Why is TPD important for watch winders?
All automatic watches contain a rotor. When agitated, this generates kinetic energy that is then stored in the mainspring within the watch movement. Different watch movements have different requirements as to how much energy or TPD they require daily to maintain enough power to keep the watch running.
How do I find the right TPD for my watch?
We have a database that is updated regularly. Firstly type the make or model of your watch and you will be presented with a list of matches. Click your model and you will see the amount of turns per day that your watch requires. Click here to visit our winding specifications database.
How to set the TPD on your watch winder
Different brands of watch winder have different control methods. This might be a twist knob, a touchscreen control or a downloadable app. Simply select from the amount of TPD available that suits your watch's requirements along with the direction of rotation. Some watch winders are pre-programmed to perform a ‘one size fits all’ single program and do not require setting – just turn on and go.
Benefits of Fully Programmable TPD Settings on Winders
Some premium watch winders are capable of being programmed to the exact number of TPD recommended by the watch manufacturer. During the programming stage (normally carried out on a downloadable app) you can set the exact turns per day in increments of 10 or 20 and select the direction of rotation. This enables the owner to rest assured that their watch is getting exactly what is required and recommended.
