About the Breitling Chronomat B01 42

The Breitling Chronomat B01 42 is one of the most recognisable watches in Breitling'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 800 TPD in bidirectional mode matches the Chronomat B01 42'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 800 TPD setting for the Breitling Chronomat B01 42 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 Chronomat B01 42 is always ready when you reach for it.

All Tempus watch winders offer fully programmable TPD and direction settings, so you can dial in exactly 800 TPD bidirectional for your Breitling Chronomat B01 42. Every Tempus winder is backed by our 3-year warranty.

Frequently Asked Questions

What TPD should I use for a Breitling Chronomat B01 42?

Use 800 TPD in bidirectional mode. This matches the Chronomat B01 42'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 800 TPD for your Chronomat B01 42 and different settings for other watches in a multi-watch winder.

Will the wrong TPD damage my Chronomat B01 42?

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.
