-: these are my top 10 faults/problems (can be in any order really as
: they are all frustrating)
: 1(cal11)Number 1 for me is the date turning wheel on early cal 11's
: that was made with a plastic tooth. slowly the tooth wears down
: and starts to fail. (Mr Ogg knows all about this one!)
: 2(cal11,12,15) the screw 5443 that hold down the setting lever on
: both 11/12/15 calibers often breaks off due to repeated use. its
: a really annoying thing to happen as it requires alot of the
: movement to be dissasembled to replace. interestingly the
: valjoux 7740 sometimes is seen with a sprung setting lever which
: solves this problem.
: 3(cal11,12,15) every heuer collector knows this one! the 8180
: chrono return lever often can break where the pusher repeatedly
: hits it, sometimes i have seen these re-welded.
: 4(cal11,12,15) the 1143 osilating weight seems to be the first
: thing to rust if water gains entry....its more the tube that
: runs down the middle fixes itself to the 8020 chrono wheel.
: 5(val72) 8270 minute record jumper is pretty fragile on most chrono
: movements and is often seen missing on cal 72's.
: 6(val72) 8221 the pin that hold the chrono reset lever. if this pin
: ever gets bent or goes out of alignment it stops correct reset
: of the chrono wheels. it can be a big problem if the hole it
: sits in is damaged on the movement plate.
: 7 removal of silverstone glass....v tricky!
: 8 monaco sprung case stays.....v annoying if stuck in!
: 9 chrono second hand pin tubes.....when worn are really annoying.
: need pinching to stop any movement when being reset. with
: patience the tubes can be replaced (good challange)
: 10 chrono pushers sometimes break off during removal leaving part
: of the tube stuck inside a watch case covering the thread. this
: is v annoying and then often has to be broched out slowly to
: save the thread from getting damaged.
