Watches can’t walking and balance sheet stop, watch winding torque may be unstable or deformed spring. After tightening the watch not go back cover, remove the movement, and then follow the normal time, fault location may be: second hand high touch table glass, not equipped with a tight inner circle of glass, causing the second hand to touch the glass table. Watch for failure analysis, fault location is also just possible to make a judgment. what happened on which one or more fault parts, specifically fashion watch must be checked in order to be finalized.
1, watch walking, weakness, balance sheet stop, where fault ?
Watch the fault may be: unstable or winding torque spring deformation, barrel cover extrusion barrel tooth bending or breaking the winding stem small rod scraping the barrel too long wheel; wheel barrel wall broken or deformed hair Article too wide, so the barrel projection lamp.
2, after tightening the cover will not go watch, where the watch fault?
After tightening the watch not go back cover, remove the movement, and then follow the normal time, fault location may be: second hand high touch table glass, not equipped with a tight inner circle of glass, so that the second hand touch the glass table, solid machine rings too high or too low, causing the machine table ring watch movement or back pressure to suppress the watch movement, the impact of the axial gap and can not rotate.
3,A faulty watch, how to determine which fault occurred in the section of the route?
Watch for failure analysis, fault location is also just possible to make a judgment. Fault what happened on which one or more parts, specifically watch must be checked in order to finalize the benefits to watch for failure analysis is to narrow the scope of the inspection, thus reducing the hassle of dismantling and thus may cause loss. Check the watch, the watch can be three line of work, first determine which fault occurred in a period which route, then the fault segment parts to be checked. Determine the fault segment method;
(1) on the bar and watch the dial needle inspection arbor.
Such as smooth on the bar, on the strip transmission line failures, this part does not have to open the inspection if they can successfully dial needle more than 12 hours (IM needle rotation), then dial needle transmission line failures. This part does not have to open inspection. If not on the bar, paid on routes open parts inspection; if they can not dial needle, the needle open dial line parts inspection, as neither the needle bar fork can not vote, then focus on the bar with the setting apart of common parts to be checked. If this is faulty, troubleshooting and then the next check.
(2) Remove the watch back cover.
Shaking the watch movement: the watch balance wheel swing as normal, escapement fork movement, escapement wheel does not move, then the prongs to balance spring segment without failure, failure in the automatic route of the barrel to the escapement wheel fork shaft section such as the balance wheel swing is not normal or does not swing, escapement fork does not move, then the fault position in escapement fork shaft to balance spring period, the need to disassemble the watch to be checked.
