Bell & Ross BR 05 Black Steel 40 TPD | Aevitas

If you own a Bell & Ross BR 05 Black Steel 40 (BR05A, BR-CAL.321), here are the generally recommended watch winder settings. These figures are based on available data for this calibre family.

Recommended Winder Settings

Setting Value
Turns per day (TPD) ~650 (typical)
Winding direction bidirectional
Movement BR-CAL.321

Why These Settings Matter

A setting of around 650 TPD bidirectional is typically recommended for the BR-CAL.321. Too many turns causes unnecessary wear; too few and your BR 05 Black Steel 40 will run down and stop. If in doubt, start at 650 TPD bidirectional — the safe default for most modern automatics.

All Aevitas winders offer programmable TPD settings from 650 to 1,850, so you can dial in the right setting for your BR 05 Black Steel 40.
