What a complete disaster, I'm really sorry to hear this. Would it be possible for someone on here who knows values of these clocks to say what it would have been worth and what it's worth now? You have evidence that you can successfully clean Heuer dials and you presumably have evidence that you told him not to clean it? Hopefully you can find a replacement dial for him to pay for and fit FOC but if not I think you're going to have to ask for a large chunk of money returned to you.

: I have a beautiful old Heuer Aircraft Dash Clock with Chronograph..
: Long story short.. I sent it to a specialist in Valjoux 5's.. nice
: guy, highly recommended. The clock needed a lot of work, and the
: dial had an oily residue all over it.. something I can clean up
: (I have experience!!)- a very delicate operation, but do-able.
: So, I left specific instructions not to touch the dial.

: Yesterday I paid up for the work so far, not a small amount either.

: I've just seen footage of the clock, that was sent to me, showing
: it working.. and the dial has clearly been wiped clean, and the
: Heuer logo is absolutely ruined.

: If anyone has a spare dial, I would REALLY appreciate it, it is a
: Heuer Ref. 430.
: See here: bottom middle..

: In the mean time, what should I do, any help or advice? As it
: stands, a huge value has been wiped (literally) off the value.
