hello everyone, I have a 2914-3 and the original crown was polished down to where you can barely make out the Y logo in the center and it bothered me so I bought a naiad crown off eBay assuming it would fit. I brought it to my watchmaker to swap and he said that the tap size is too small to fit the stem, then I started thinking about it and the 2913, 2914 and 2915 all have different movements so that makes perfect sense. However why is it commonly advertised that they are all the same crown? So now I have a crown for what I think is a 2913 but I'm not really sure but I'm scared to buy another crown for my railmaster since it might be a waste of time and money again. I mean I'm sure someone out there needs a crown for their 2913 but it's still a hassle. Can anyone clarify the tap sizes for each crown or have any other distinct differences between the 3 crowns just so I know going forward? Thank you in advance!
The 2913 and early Seamaster's are Tap 9 (smaller ones circled) Speed Masters are Tap 1.0mm Im not sure which size the 2914 is, but they should be the two lower crowns on the left
Thank you for all the info! All I know is it was too small for my stem. My watchmaker thought I needed tap 9 but idk. Here are the pics...
The 2913's crown tap size is 0.9mm, 2914 is 1.2mm and 2915 is 1.0mm. They also differ in their tube size as well.
Thank you TNT! So they are all completely different. Well if there's anyone out there who has a 2914 crown and needs a 2913 drop me a line
