: I have a "economy" Beads of Rice from a 1163V but it is
: very slack, albeit complete - can they be tightened again?

If anyone can it's Michael Young in Hong Kong. http://www.classicwatchrepair.com/

He (actually they) did a fine job on a very beaten up 1960's Oyster bracelet of mine. Turnaround was faster than quoted and price exactly as agreed. Just one thing, if you have any special instructions such as "Do not polish" attach a note firmly to the item. The people who actually do the work may not be able to read the exchange of emails in English with Michael himself. Otherwise well recommended. Although I was worried about the two-way dispatch half-way round the world it went without a hitch and I have not seen a comment anywhere about shipping going wrong.

Drop me an email for before and after photos if you like.
