HydroConquest: L3.644, L3.651, L3.673 TPD & Winder Settings | Swiss Watch Store
Every automatic watch has a sweet spot for winding, and the Longines HydroConquest: L3.644, L3.651, L3.673 is no exception, with its automatic calibre. Rather than guessing, this page gives you the verified turns-per-day (TPD) figure and winding direction for the HydroConquest: L3.644, L3.651, L3.673, so you can dial in your winder with confidence.
The correct TPD for this watch
Use 800 turns per day with clockwise rotation. This is the manufacturer-appropriate setting for the HydroConquest: L3.644, L3.651, L3.673. 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 HydroConquest: L3.644, L3.651, L3.673 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.

Pick a programmable winder, set the TPD and direction from this page, and it will stay perfectly wound.
