Ed an asianwatchforum regular is sourcing these from Sea-Gull HK and they are coming with papers from Sea-Gull.
The Sea-Gull ST19 powers the watch and is an awesome handwound column wheel chronograph. They are coming out with this watch in a 40mm size and I will probably snag one of those at one point. While this one is 38mm it does get time in the rotation. I have had 4 1963s now and 1 was an original.
As I mentioned I owned an original 1963 until recently:
I'm also a fan of this M192S Chronograph which also finds time in the rotation:
Plus you can admire the ST19 movement whenever I want to:
Sea-Gull makes some beautiful watches and like Seiko they are an affordable watch with "in-house" movements. The ST19 in the chronographs are cool because they are the direct descendent of the Venus 175 which Tianjin Sea-Gull bought from Venus to put into the original 1963 Air Force watch. Very cool!
I used to be Sea-Gull Canada so I can chat with you about Sea-Gull until the cows come home.
While this is not a Sea-Gull it does have a Sea-Gull ST8000 movement in it. One day I would like to buy a dual Tourbillon Sea-Gull. :P
Not sure what you guys think of an affordable Tourbillon. Is that an oxymoron?
