I just ordered it. When my modder takes it apart, he will let me know everything about it and I can post what he finds. I had a few FC so far. The HF FC was different than the JF. Bezels weren't interchangeable and the HF crystal was only 2mm thick (it was same crystal as 15400). The HF was 13.95 thick if I remembered correctly, the JF was like 14.5 ish
Unfortunately when I ordered the JF it was supposed to have a 2824 in it- but instead it came with a Miyota 9015, so beware when ordered a JF, have TD verify date wheel rotation direction.
just couldnt resist could you lol I have my TD checking stock for me
