I've recently acquired an Aqua terra 41 mm with the 2500b movement .. I've noticed after setting the time the watch requires a bit of a shake to get it moving again(fully wound) is this normal for the watch and if not .. What's the approximate charge from omega service to tune this watch up? Thanks in advance .. Omega newbie
The 2500B is known for mediocre self starting. Difficult to say that what you are seeing is normal or not, but it is a known thing on this movement. The 2500C is better in this regard. Cheers, Al
