HydroConquest Watch Winder Settings | Tempus

A watch winder is the simplest way to keep your Longines HydroConquest running between wears. Longines' accessible Swiss dive watch with silicon balance spring.

The key is matching the winder's programme to the movement inside: too few turns and the reserve runs down, too many and you are just wasting energy. These are the settings we recommend for the HydroConquest.

Recommended Winder Settings

Setting	Value
Turns per day (TPD)	650
Winding direction	Bidirectional
Movement	Calibre L888
Reference	L3.781.4.06.9

Setting Up Your Tempus Winder

Select 650 TPD and bidirectional rotation on the winder's control panel — on touch-screen Tempus models this takes seconds. Place the HydroConquest on the holder, close the lid, and let it run. Check after 48 hours: if the watch is running accurately and holding its reserve, the setting is right. Tempus winders run whisper-quiet, so a bedroom or study placement works well.

Frequently Asked Questions

What TPD does the Longines HydroConquest need?

The recommended setting is 650 turns per day, bidirectional. Most Tempus winders cover this range with programmable TPD steps.

Which winding direction for the HydroConquest?

Bidirectional rotation. Tempus winders offer clockwise, counter-clockwise and bidirectional modes, so this is covered.

Can I leave my HydroConquest on a winder all the time?

Yes. Modern automatic movements have a slipping mainspring that prevents overwinding, so continuous gentle rotation is safe. An incorrect TPD setting will not damage the watch — at worst it simply will not stay fully wound.

Does Tempus offer a warranty on winders?

Every Tempus watch winder carries a 3-year warranty, and Tempus can repair any Tempus-brand winder even once the warranty has expired.
