these round cases came out in 1947 and continued until i dont know when. the square cased model came out in 1951, but you rarely see them. i had the museum edition which was too much bling for my liking.
funnily enough i have seen an influx of cosmics online over recent months. having owned the re edition its no longer a watch i would search for again. i dont really like moonphases as you need to either keep it running or be very accurate when you set it.
its a big shame about the dial conditions on many of these pieces. they do hit the value big time so not a brilliant investment. the problems of living in a high humidity area like yours.
thanks for the pics Nilo and thanks to the owner for allowing them to be shown.
