Correct, it does not have a screw down crown. The crown is quite worn and I can't see the five dots. Any idea where I can get a crown? Also a bezel insert?
IMHO if the crown is original (even used) you should keep it like this - not easy to find one. I love the so called "ghost"insert!!! Don't touch it Again just my humble opinion
Also the dial seems dirty...or is that just the way the lume ages? I won't have it relumed, but can the lume be cleaned?
I like to wear mine on a suede strap. Orignal Gay Freres bracelet is not easy to find and expensive. I don't like the nato as the case is already pretty thick. For the tritium on the dial I wouldn't touch it - but maybe OF members have a different opinion and know a watchmaker able to clean it
