Bulova parts interchangability

[Nucejoe]

I Need an escapement wheel for bulova  11blacd. The family beats 18800  and includes various movements ranging  from manual wind subsecond , automatic, auto with calender, auto calender date and so on.

Am I correct thinking the escapement wheel off of any member of the family fits all members? For instance, do  11 BLA and 11BLACD escapement wheel interchange? 

Thanks in advance.

I have looked in my "bestfit" catalogue and the usual web sites and can not find the details for a 11blacd. However looking at the "bestfit" the Bulova's are not as interchangeable as you suggest so I would double check before any purchase.

The assumption is correct BL, BLA,  BLAC, BLACD is all based on the 11AL and seems to have the same balance.

I’m always wary of signing up for free downloads, but you can get the tech sheet from Cousins which is another source of the info above

Hi stuart, Thank you for sending the link, I would have got lost trying to navigate cousinsuk. I got no access to paypal or major credit cards, so easiest to shop domestically which has gone dry over the past fourty years of no US brand. I may get some result if interchangable. Much appreciate your useful help.
