Alec,
These aren't my specialty, so maybe someone else can chip in about the bracelet and value. I do know that they are pretty darn valuable. Getting hold of an original bracelet will be difficult. I believe they came on a GF beads of rice bracelet (well the Heuer variants did), and these are highly sough after and go for £350 to 500 ish.

I presume you are based in the US, and for servicing/cleaning I would recommend Craig at http://www.chronodeco.com/, he is well known on here and knows his Heuers/vintage watches well.
