The catalogue dates run from Christie's circa-1920 estimate for steel case 1004619 to Antiquorum's circa-1940 estimate for steel case 1004623. Antiquorum dates gold case 1005651 and steel case 1004626 circa 1925. These are dates assigned to individual watches; they leave the reference's production endpoints open.

~~Collector Square preserves~~ Tajan's 2007 entry ~~for~~ a gold ref. 2226 marked “No 105650” and dated circa 1935. Auctionata's 2014 entry gives case 1005650 and circa 1930. Their low-resolution images show the same Ronchi Milano signature and two-tone dial, which points to a repeat offering. The number discrepancy remains unresolved, so the entries count as one candidate watch.
