Ziggy? Asian 7750 (non-modified seconds at 9) 6'o clock subdial resets but falls down to "4" after 20 minutes?

As the title says, this watch works fine but after reseting the chrono, the 6'o clock subdial with not stand up straight at 12 for too long at will settle at 4 or so....is this an easy fix for a watchsmith? Why is it doing this?

Try to press the reset button again, deeply, and several times (when the crono is stopped!!)

Sounds like the brake lever is not working on the subdial, or the hand is loose.

Try this, start the chrono, then Stop it - DON"T reset, only stop, see what the hand does. In the Stopped position the brake lever should be holding the gear fixed and it shouldn't move.

Let me know what you see.

If it's the brake lever that is defective, you have to take the dial and hands off, and the top bridge off to access the chrono levers and brake.

Ziggy is right -- either brake issue or the chrono hand has become loosened on its tube (a very common problem). If the hand resets to a different position every time you reset it, the hand is probably loose. You need to remove the hand (I would do all 3 chrono hands at the same time since they are probably also loose) & apply a tiny speck of cement (I use a slow-dry metal epoxy). If the brake is the problem, this may be helpful.
