Ingenieur Automatic 40 TPD & Winder Settings | Swiss Watch Store
The IWC Ingenieur Automatic 40 (reference IW328901, powered by the Calibre 32111) is a fine automatic timepiece — and like every automatic, it stays at its best when kept wound between wears. This page gives you the exact winder settings: turns per day (TPD) and winding direction.
TPD and winding direction for the Ingenieur Automatic 40
Your winder should be set to 800 turns per day (TPD) and rotate bidirectional (rotating in both directions) to keep the Ingenieur Automatic 40 properly wound. It is a simple two-step setup on any modern programmable winder.
Why the correct setting matters
Correct winding settings keep your Ingenieur Automatic 40 in its comfort zone: power reserve topped up, rate stable, ready to wear without adjustment. Fall short on TPD and the watch runs down and stops; overshoot and you are just spinning the rotor for nothing. Either way, a modern automatic is safe — its slipping mainspring prevents any overwinding damage — so treat the right setting as a matter of accuracy and readiness, and of looking after a fine watch properly.
Choosing a watch winder for the Ingenieur Automatic 40
Look for a quality programmable winder where you can dial in 800 TPD and bidirectional exactly. One automatic in the rotation? A single winder does the job beautifully. Several automatics in the box? Step up to a double, triple or larger winder so nothing sits idle. Explore our watch winders to compare.
