Conquest Automatic: L1.641 Chronograph TPD & Winder Settings | Swiss Watch Store

Own a Longines Conquest Automatic: L1.641 Chronograph? Getting the winder settings right means the difference between a watch that is always running accurately and one that keeps stopping between wears. Powered by its automatic movement, this model needs a specific number of turns per day and the correct rotation direction. Here is everything you need to set your winder up correctly.

The correct TPD for this watch

Use 650 turns per day with bidirectional (rotating both ways) rotation. This is the manufacturer-appropriate setting for the Conquest Automatic: L1.641 Chronograph. A programmable winder makes this a one-time setup — configure it once and the watch stays correctly wound indefinitely.

Why the correct setting matters

An automatic watch is a machine that feeds on motion. When the mainspring is fully wound, the watch runs at its most consistent rate; as the reserve drains, accuracy can drift and complications like the date may need resetting. The right TPD keeps the reserve topped up, so your Conquest Automatic: L1.641 Chronograph is accurate and ready to wear whenever you pick it up. It is worth knowing that a wrong setting will not damage a modern automatic — the slipping mainspring simply releases excess tension — but a watch wound at the wrong rate is one that is often stopped or running flat.

Winder buying advice
