Hi Sam
Great photo shoot!
Your 1959 Omega Seamaster 9068 auto, 14k YG/leather, white applied indices/chronometer (505) , caught my eye. The case on that one looks to be a domestic variety. Will you confirm this ? Norman Morris ( Omega US Distributor ) would import dial and movements and case some watches in the USA. Your Seamaster chronometre seems to be one of these... I had one like it about 14 years ago.. I dont see these at all...
Good Hunting
