The C-130J entered service with the RAF in 1999 which would tie in with a 2000 production date for the watch.
These custom dial watches are usually a limited edition of about 50. The individual number is often etched on the back in the style xx/50.
Andrew Michaels Jewellers (a sponsor of this board, link at the top of every page) has produced many limited editions for the forces so it may be worth contacting them.
Value of custom dial limited editions is normally slightly less than a standard dial since the appeal of the watch is limited to those with an association with the design.
Hope this helps.
