Here you see another swiss dialed 7924 but now as civil version with the later 292 xxx serial..





As we know now not many were made, estimate between 160 - 300 so al Big crowns of Tudor are rare..the Rolex 6538A will beat it by numbers and probably the 6200 & 5510 also but there were made for a short time.IMHO more 6538 are around and there are different variations within the Tudor BC serie, lets say MK's. Most are knows as 7924 and many went to the MN and were used in combat..see it on one of the casebacks..it had to be opened quick..Servicecenter in Toulon ordered a new one but it never came..because there weren't any left was the message back from Geneva so it went on in this condition...





They had to be serviced and many lost their original dial and replaced with silver printed t-swiss-t dials, the 275xxx serials - '58 were real combat watches, the later 292xxx '59 serials were for civil use. The earlier Swiss dialed Tudor 7922 & 7924 were i started with are more prototypes and i haven;t seen one before 1'56 yet & the line here is very thin here to the rolex big crowns. The small case 7922 were probably the earlier solution for the MN. The rolex 6538 cased are in my eyes the MK1, the combat 7924 MK2 and the later civils the MK3 and the 7928 Square Crown from '59 will be the MK4. All these Tudors are rare and use almost the same case & 390 caliber. No big difference like we see in the DRSD list because of the much higher quantity and longer production in the later series...
