Khaki Field Automatic Watch Winder Settings | Tempus

Hamilton's military-heritage field watch with 80-hour reserve. The Hamilton Khaki Field Automatic is an automatic watch, so a quality watch winder keeps the mainspring topped up while you are not wearing it.

Getting the settings right matters for accuracy and convenience. Here are the turns-per-day and winding direction we recommend for the Khaki Field Automatic, plus Tempus models that handle them effortlessly.

Recommended Winder Settings

Setting	Value
Turns per day (TPD)	650
Winding direction	Bidirectional
Movement	Calibre H-10
Reference	H70455533

Note: published TPD guidance for this reference varies slightly between sources. The setting above reflects the most widely cited figure; any quality winder with a nearby programmable setting will keep this watch running happily.

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 Khaki Field Automatic 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 Hamilton Khaki Field Automatic 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 Khaki Field Automatic?

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

Can I leave my Khaki Field Automatic 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.
