Carefull there when you manually wind the lebron.
Basically the A3126 on your AP is an A7750 with decorations mimicking Cal.3126. The A7750 with second hand at 12o'clock is considered as a time bomb because the non jeweled additional gears upon moving the second hands from 9o'clock (it's native second hand position) to 12o'clock, and there are rules upon treating the A7750 (see the A7750 movt section for more information)..

Try to find yourself a friendly Watchsmith and service the movt mate, see how it's turns out.
I will definitely take a look and consider that. I've had no trouble so far thankfully, I think it may just have been due to it sitting still for a long time, so I hope it stays that way for a while. I'll still look for a watchsmith just in case but I hope it doesn't come to that.
Thanks for taking the time to help me out! Appreciate it.
