- Accuracy: 20 ~ +40 seconds per day – Artifice HoroWorks watches are regulated to between 0 – +8 seconds per day.
- Shock resistance Shock-absorber device for balance staff
- Vibration frequency 6 vibrations per second (21,600 vibrations per hour)
- Day & date display with quick day & date correction available
- 7S26: 21 jewels
- 4R / NH / 6R /NE: 24 jewels
7S / 4R / NH: More than 41 hours
6R / NE: More than 50 hours
All: Automatic winding with ball bearing mounted rotor, bidirectional winding, one way clutch. Typically, 2-3 minutes of winding via shaking wrist back and forth with result in a near fully wound movement.*
4R / NH / 6R /NE: – Manual winding via clockwise rotation of crown, AKA “hand-winding.” Screw down crowns (e.g. SKX, SRP777, A7, Oban divers) must be unscrewed counter-clockwise until crown clears case tube threads before winding. 48 complete rotations of the crown will result in a fully wound movement.*
*60% wound should be adequate to power a movement through most of a day, and additional movement while being worn will accumulate as well. It is not necessary to constantly keep the movement “topped up,” however, many movements will not keep good time if they are nearly unwound.
Handling and Corrections
1) Crown at normal position
- Clockwise : Manual winding (excluding 7S)
- Counterclockwise: Free
2) Crown pulled out to 1st click
- Clockwise: Quick day correction
- Counterclockwise: Quick date correction
- Do not set day/date between 9pm and 3am- day and date mechanism may be damaged. If you must change day/date during those hours, proceed to 2nd click and change time to 3am or later, then proceed to change day/date, finally correcting time afterward.
3) Crown pulled out to 2nd click
- Time setting
- Second hand stop, AKA “hacking”
- Never set the time, manually hand-wind the movement, change day or date, or manipulate the crown in any way while your watch is submerged.
- Do not handle highly magnetic objects (e.g. audio speakers) while wearing your watch.
- Do not subject your watch to extreme vibrations or impacts if possible. Shooting firearms is perfectly fine; wearing your watch while operating a jackhammer is not advised.
