About the Longines Legend Diver
The Longines Legend Diver is one of the most recognisable watches in Longines's collection, admired for its craftsmanship and enduring design. Like all fine automatic watches, it relies on wrist movement to keep the mainspring wound — which is exactly what a quality watch winder replicates when the watch isn't being worn.
Setting your winder to 650 TPD in bidirectional mode matches the Legend Diver's calibre requirements. This keeps the power reserve topped up without unnecessary wear, so your watch is always ready to wear with the correct time and date.
Why Correct TPD Matters
Every automatic calibre has an optimal winding rate. Too few turns and the watch may run down; too many is simply unnecessary. The 650 TPD setting for the Longines Legend Diver is the sweet spot recommended by winder specialists — enough to maintain a full power reserve, gentle enough for long-term care.
Modern automatic movements have a slipping mainspring that prevents overwinding, so an incorrect setting won't damage your watch. But getting it right is the mark of a careful owner, and it ensures your Legend Diver is always ready when you reach for it.
Recommended Tempus Watch Winders
All Tempus watch winders offer fully programmable TPD and direction settings, so you can dial in exactly 650 TPD bidirectional for your Longines Legend Diver. Every Tempus winder is backed by our 3-year warranty.
Frequently Asked Questions
What TPD should I use for a Longines Legend Diver?
Use 650 TPD in bidirectional mode. This matches the Legend Diver's calibre specification and keeps the power reserve fully wound.
Can I use the same winder for other watches?
Yes. Tempus winders let you program each rotor independently, so you can set 650 TPD for your Legend Diver and different settings for other watches in a multi-watch winder.
Will the wrong TPD damage my Legend Diver?
No. Modern automatic movements can't be overwound thanks to the slipping mainspring. The wrong setting just means the watch might not stay fully wound — it won't cause damage.
How long is the Tempus warranty?
Every Tempus watch winder comes with a 3-year warranty as standard, covering the motor and electronics.
