Hobbit,
Your SM 300 does not seem to have any patina?There's one for sale with gloriously even patina asking over US$4k
Will pull the trigger if one comes along at a fair price. that 1675 has got even pat....
besview,
Like sshark said, mine, like the watchco version are fitted with new luminova dial, hence no patina. So I always consider mine as a homage to the original.
As for the 1675, that watch is very old. It is about 46 years old, bought in 1964. It is in retirement after being used (not abused) on a daily basis for over 30 years (not by me). It has been to RSC over 6 times in its life, had its bracelet changed 3 times (I have all the bracelets) and all the documents and service papers. It has been down manholes, up trees, swam in the ocean, driven round Malaysia, slept with, basically never left the owners hands.
