Thank you Hermann, psrivats and Rod
I do love the variations you have here, wonderful and some quite rare The 1965 4420 is very nice and will look even better with a newer crown
But the 5606-7010 is very nice, what size is it? I have found in the past that the LM's are a little on the small size for me
The 7010 is simular sized as the rest of the 5606-7XXX 36-37mm, this watch is going to be a gift fore my brother when he turns 18 in May
If you need a bigger LM some 9XXX series is in the 38-39mm range, the 9040 is a big LM.
The 4420 is from November 66, might be one of the last ones?
