All things being equal, is a flip open case more or less rare/valuable than a standard screw on/off case? Housing a Bunn Special. Thanks

Hi Robert , I am having trouble with the answer, later 16s bunn specials are factory cased, do you have a picture and serials ?

Regarding the case itself I have seen more screw back and bezel cases than swing out.

Most collectors prefer SB&B cases as it is easier to view the movement and when opening a swing out there is always the possibility of the dial "encountering" the case and getting damaged.

Thanks. Bunn #4420045; Case #1027406 About 1923

Case is an E. Howard Watch Co. Keystone Extra 14kt gold filled

That makes it easy , I like 18s bunns , but I know a little , around this time Illinois started to case their watches although you could still get movement only for a few more years . That case belongs to an E. Howard if I'm right , an ebay marriage? Check out the the Illinois section for info on case's . Hope this helps

What you call a flip open case is a Double Hinged Back & Bezel case. An EHoward& Co case is entirely wrong for the Illinois Bunn Special. At the time in 1923 the Bunn Special would have been cased in a period correct Screw Back & Bezel case.
