Alex, not sure how high demand is on these - the 7730 was used in the Carrera, Autavia and Camaro 30s and the Carreras at least had a relatively short lifespan as Heuers go. The replacement 7733/4/6 movements use an entirely different bridge (the sort of heart-shaped solid one). So I'd say demand is lower than for the Val 72 and 92, but it's reasonable to assume supply is lower to match - the bridge might also fit the Venus 188 the 7730 was developed from (Valjoux bought out a failing Venus in 1966) and that was in production for much longer.
