Hey guys, I'm looking for the specs on the original crown for a Centenary 30.10 JUB 2500? Diameter? Width? Size of hole on the inside of the crown? Thread size? Anything you have would be helpful. I know there are a couple of guys on this forum looking for the same info. As these watches become older we are going to see more and more of these watches without the original crowns. http://www.ofrei.com/page_147.html#7994 Bestfit 8100/1005 These ones do not look like the original crown. I'm betting some of the vintage watches used the exact same crown so I'm looking to see if I can get one of these but I need the specs first.
Come on guys! Somebody with one of these watches, pull it out, grab a caliper and measure the crown for us. Even just an accurate diameter and width measurement would help.
