Exactly what I did when I got mine. Except the nato strap is from Omega so it looks proper..
Probably just me but I can't stand the lollipop seconds hand of the Spectre. I've grown to really like the standard model instead.
As for Spectre vs NTTD:
I remember many complaining about the patina on the Spectre/SM300MC when it first came out. Well clearly the patina on NTTD is so much louder. The patina doesn't look so bad on the SM300MC now does it.. Lol
