This is a watch from my collection – a Sea-Gull 1963 chronograph. It’s a replica of a chronograph Sea-Gull manufactured for the Chinese air force in 1963.
The movement is a clone of the Venus 175 movement, which Sea-Gull now calls the ST19.
Just right up my street – no frills, clean dial, just does what it has to do. It’s hand-winding, and has a normal second hand dial at 9 o’clock, and the minute counter dial for the chronograph at 3 o’clock.
Nice case. I’ve replaced the original fabric strap which was pretty useless with a leather strap.
Great looking movement with a 40 hour power reserve.
This little video shows the chronograph engaging, disengaging and resetting.
Not a bad copy indeed.
And, the biggest surprise – performance on the timegrapher half-wound. You can’t argue with that!
Go and get one whilst you can.
Hello Christian, May I ask what Lift Angle setting you used for the ST19 when you had it on the timegrapher? I can’t find the figure published anywhere.
The original Venus 175 has a lift angle of 42 degrees, but I’m not sure that the clone has that, too. My guess is more towards the usual 52 degrees.
Thanks for the reply Christian. Since I didn’t spend a whole lot on my ST19 watch I think I’m going to open it up and try to observe when the amplitude is at 180 degrees.
I recently checked my st19 chrono for the correct lift angle. I used the marked balance method at 180 degrees. I seemed to get a lift angle of around 47 degrees, give or take a degree. Its certainly not more than 49 degrees.
according to puretime, the correct lift angle is 50°.
They used this on their timegrapher while checking a Speedmaster with ST-1902 movement
180 degree method is nice but slow motion phones could do the job too … https://www.youtube.com/watch?v=4yDjWx-pVwQ

Very nice watch !
I just receive a Strela (3133 Poljot), but maybe the next one will be a “1963”.
Thx for sharing your opinion !
Which version did you get, from Thomas, ebay or watchunique? Wanting to get one, but don’t which version is the best one to get.
I got mine off eBay from wilsonwatchworks – probably a good half year ago.
This chronograph is really tempting; I’m hesitating between this one and a poljot 3133.
I’ve read somewhere that you can damage the 3133 movement if you press the reset button while the chronograph is engaged. Is it also true with the ST19?
I really like the blog by the way!
Doesn’t look like it – I’ve just tried it, and the watch is still working 😉
I have one too! Its very nice! Now only if I knew how to tear it down and clean it!
