Rolex Yacht-Master 42 TPD & Winder Settings | Aevitas

If you own a Rolex Yacht-Master 42 (226627, Calibre 3235), here are the correct watch winder settings to keep it running accurately without overwinding.

Recommended Winder Settings

Setting Value
Turns per day (TPD) 650
Winding direction bidirectional
Movement Calibre 3235
Recommended Winder

Why These Settings Matter

Setting your winder to 650 TPD bidirectional matches the Calibre 3235's power reserve characteristics. Too many turns per day won't damage a modern automatic (the mainspring slips), but it causes unnecessary wear. Too few and your Yacht-Master 42 will run down and stop, losing time and date.

All Aevitas winders offer programmable TPD settings from 650 to 1,850, so you can dial in exactly 650 for your Yacht-Master 42.
