Looking for same crown as shown on this watch (thanks much):

 

unsigned buddy what's the tap size and head over to OUR BLOODY EBAY PAGE!!! sold a box of 40 or so coin edged crowns last week mixed tap for £5.50 free postage...

 

sorry I don't get the point. I'd appreciate if you could refrain from making unpleasant comments on my post to promote your business.
if your crowns are already sold I'm not sure how useful your comment is.

 

i do im saying check.. literally a full box.. sold shame... what tap do you need? i still have a few. how many do you want? no im just disappointed you missed them thats all dont get me wrong..

 

and dont be prickish im hardly promoting my page to anyone but you on your post for bloody crowns.. im not mass marketing guerilla advertising tactics here . i think you being a bit tetchy.. I can delete my reply and PM if that makes you happy..

sweet jesus i was trying to help..

 

i don't know what the tap is, it's a crown for caliber 30T2SC. I'll ask friends if they know more info about the specs.
I have since been sent a crown that's correctly sized but looks slightly different. I'm looking for just one, exactly correct crown. thanks for the suggestion.

 

S, you'll have to excuse FullyWound. He certainly picked the correct screen name, and FullyEarned his avatar message as you can see.

 

cool either way i have 100s look like they fit the bill ill spend 20min or so tomorow and match some up using google found info and i may even have a 30t2 to check against the only problem MAY be a) it maybe one of those "dodgy calibers" that has a bunch that fit (and thus dont) but also that the length f your stem may play a factor as they do sit slim but ill send a bunch anyway im sure the age old tradition of trial and error will overcome. PM me your address ill send you a packet monday

 

just to check tho.. case is all steel not chromed and how shiny is your case is it "just like picture? because some are NOS so pretty shinny but i guess you could just scuff em a bit?

 

I'm not sure if the pic is of your actual watch or not, but if you have the old crown, you'll want to go to you watch maker so he can measure the tap, tube, etc. Once you have that, perhaps these charts will help you find the model number of the correct crown. See pics

 

Wow, that is astounding, thanks gents.
If "tap" means the diameter of the stem then my watchmaker told me it should be 1.2 millimeters.
The other measurements provided by a friend are:
Diameter = 5.9mm
Depth including threaded tube = 2.75mm
Depth excluding threaded tube = 1.55mm

Here's a picture of the actual watch it's intended for:
