Sifu? Nolah, lots more to learn. Need to get one of the moon watch. Got the book (A Time Capsule), but not the watch.
Besview,
Love the 35th Anniversay watch. I gave that one a miss recently and got a MacBook Pro. Sigh... not meant to be. Another came up and still did not get it. One of the best looking Speedmaster IMHO. I love the case back.
Manburg,
I was lucky to get the X-33. It is Gen 1 and early Serial number, placing it around the launch date. Got it at a good price. Comes with the titanium bracelet, 'local' long canvas strap ala NASA version and a Taikonaut NATO strap. I got the Kevlar strap to make it 'more like' the watch used by the astronauts.
