Hi everyone! I bought an Aeromatic 1912 A1308 watch (have not received it yet) and I was wondering what caliber does it use. By chance I found the attached pictures, I believe it's the same caliber but I found no information on it, only that it may be a Seagull. Can somebody help?
Join me as I strip down, service and review this Chinese ETA 2892-A2 clone. Seagull ST1812 watch movement. There was a couple of issues to deal with but altogether a fairly impressive movement for the price.
I just got a new Chinese movement (TY2867), and when I push the winder in, the movement won't start. I've manually wind it a few times, pull the winder out and push it back in.
What could be the issue? Thanks
I am struggling to find a way to remove the movement on this large Ingersoll watch from its case. Cannot seem to find any screws that pin the movement to the case.
Tried to remove the steel spacer, it is un-movable even with pliers.
Does it mean that that I have to come from the glass? If through the glass, do I pry on the small opening on the bezel (see the second picture attached)?
considering this is not a hacking movement i would agree with JD, if it is hacking then the crown is not seated correctly and the watch is hacking......but i will put my money on it that it has a dirty stuck mainspring vert common on these older watches i see all the time, and the seller means putting pressure on the crown as if your trying to wind the watch, that pressure basically forces energy on to the train forcing it to tick, once crown is let go the tension comes off and the watch stops. in this case the mainspring will need to be changed or cleaned, oiled, and re installed.
the screws support the pinions when pressing hands on. the hand being off could have just been you not pressing on perfectly. as far as clone 7750 goes they really arent top notch when compared to the eta, the chinese have no quality control and the chrono arms always have more play in them compared to the eta because of the way they are riveted together, make sure there is no play in the rivets.
but the spring is 100% your issue it may be popping out when hit the start button look at the pic i attached the spring should but up against the pinion arm. that spring pushes the arm and allows the pinion to make contact with the center wheel which makes the chrono run when you hit the start button, then pull back when stopping chrono.
also i have to ask is the rolex real? if so go spend $400 and get an official valjoux 7750. you will thank me later
