Like the knurled knob. As I said in my post, the lower arm can still flex a bit if squeezed hard against the stop screw. I had in mind to stiffen up the arms to prevent this but not got round to it yet. Bergeon haven't contacted me yet! Soon be available from China no doubt! 😆😆 -
Think i've stumbled across it by accident. Looks very much like Seagull ST6 to me! -
My wild guess is that it's lume. It's interesting dial in that they printed the outline of the numbers. This would allow somebody to hand paint the luminescent material on and know where to do it. It'd be interesting to knowing the time frame that the dial and/or watch was made. I'm guessing because it says the word waterproof we can narrow it down for that. Finding a modern luminescent material that's darkening colors going to be interesting. Then because this is a holder luminescent material it's probably dark because it's radium based. But you need a Geiger counter to verify that. -
I fully let the power down. Turn the barrel by finger, you get a feel of the torque the movement takes to start running . That would give you an idea if you get inadequate torque out of both spring( unlikely). Next check turning( by spoke) wheels of the train. Make a habbit of this tests to get the hang of it. I didn't get to read all said so far, but agree with JohnC. 1-Oscilators grously out of beat wont self start. 2- Bad pivot. 3- Fork pallets badly out of adjustment. 4-No end shake on staff, fork arbout and escape wheel. Make a habbit of checking the oscilator, See if pivots jump out of jewel holes as you gently raise one side of the balance wheel. Good luck
