Vintage Speedmaster Crown. Tap 9 is 1.0MM, which is correct for the early Speedmasters. This is the real deal,with the crimping on the back. Please note the small ding below the logo, otherwise in good used condition. I wouldn't trust this to be water resistant given it's age, so you're obviously just buying for the original look. $450 net to me via paypal gift or chase quickpay.
