Worldwide, vintage watch inventories are being decimated by high gold prices and many wonderful movements are now left orphaned. Although this situation provides a good source of spare parts for now, the idea of re-casing these watch movements in modern steel bodies, even vintage-style reproductions, may be an idea just waiting to happen. That has been the trend, in a small way, for pocket watch movements re-cased as oversized wrist watches. Martin, you have two practical but unpleasant alternatives. You can try to locate another vintage V&C model with a damaged caliber 466 movement for a swap-out (you may also need the dial), or locate another brand with a similar 9 ligne "thick" caliber and machine an aluminum holder if necessary. I don't recall the base JLC ebauche for the 466, but that may be a source. Either will prove difficult .
