I just learned when timing a watch you must know the lift angle! I found the LA for my Tissot Seastar with a 2824-2 movement. It is 50 and I have been timing it at 52 which gave me an average of -10.2 s/d in 5positions fully wound. When I adjusted the LA and retimed it I had a delta of 5 and it now averages +2.2 s/d in five positions fully wound. What a difference knowing the lift angle can make. I also found know a way to find the LA when you can't find it or there is no more info on it. All
