I bought one last month by top dollar... but very disappointed and can't tell if it made of 904 stainless steel.
The watch was claimed that contained a clone 3186. But the fact is, that is a cheap clone ETA (not real) has the "3186" mark.
Date window is wrong shape... the worse thing is, there is a small gap in between the two tone bezel.
Now, I'd disassembly the watch... only keep the watch case and start a Franken 116710.
Now I spend another dollar to bought 1. Gen 116710LN bezel 2. Gen dial and hands 3. The SH3135 is on the way to me.
Asking Mike for a help to convert the 3135 to 3185 and put it together.....
