Ditto what the others have said...as well:
UPO:
Crooked logo.
Fixable...pop off the dial, re-centre and glue
Tag Link A7750
Chrono second hand wont reset back to 12` marker.
Broken bracelet pins.
Fixable with movement servicing...common problem. Broken pins are unfortunately another common cheap Chinese rep QC problem. Posting a request for spare pins might find a member who can help you out.
TAG Carrera A7750
O-ring sticking out from the case.
Common. You might have to get a replacement gasket from a watchmaker as the one in there if it's sticking out is probably stretched too much. This is cheap. Either the gasket wasn't seated properly when the back was screwed on, or was the wrong size.

Cant screw in crown. Date wont change. Chrono hand wont reset back to original position.
Not sure if the crown is supposed to be screw down or push in...By-Tor would know. The date change happense sometimes because there sometimes isn't a washer to hold the datewheel down and the gap between the dial and movement can be too much causing the wheel to slip. Cheap fix by any watchmaker. Chrono pushers not resetting to 12-o-clock is very common and fixable with movement servicing.
PAM 104
Crown head fell off.
If the crown fell off, it might be able to be screwed back on and loctite applied. If the stem snapped off, that might involve more work.
Hope this helps.
