Then the big Brother the Hamilton Model 21

Only one missing was the Hamilton Model 22 deck watch / pocket watch version same movement as the model 22 in gimble box above. Well I just bought this one off Ebay from the same seller I got the big brother model 21




Now I got a complete set the Two versions of the model 22 and the big brother the model 21 and the comparing watch. One collector of these told me in WW2 they had 2-6 chronometers on ships less on smaller ships more on larger ships one on the bridge and the rest in different locations of the ship to protect them if the bridge gets a direct hit and it destroys the chronometer they have another to take it's place they were that important for navigation.
