I need some help here before I end up buying something that wont work........
I have a Seiko 6106-6439 and have been told that the correct crystal part number is: 330W16GN
That's all well and fine and I'll go along with that but I found a seller who supposedly has the correct crystal for my watch but he states it will fit a 6106-6430
Does the 6106-6439 take the EXACT crystal as the 6106-6430?
I need to make absolutely certain because if its one teeny mm or so off it wont work!
