The gen watch that Joshua shows just is not right and why you are all searching the web for gen pics when I posted some good pics of my gen 1655 I don't know!!
You can see in the top picture that the rehaut is all worng on the rep. It should not be thick and visible like on the Sea dwellers and on the side profile showing the crown, the gen crown is central just like the rep. This is not possible! See my gen below. The crown is above centre as with all 1570/1575 models.
Here is another picture showing the dial detail. The outer markers should indeed touch the rehaut.
THe straight seconds hand was only on the Series 1 as was the folded band with 385 endlinks. THe series 2,3,4 had the dot seconds hand with 78360 bracelet and 580 endlinks. Just my thoughts Joshua! and I have a gen in front of me!
