Fixed bars are the "regular" as they were invented before spring bars.
Spring bars should be called extensible bars or "self setting" bars.
Same as the term wrist watch itself; they used to be called wrislets, because essentially they were smaller pocket watches worn on the wrist.
From now on please refer to a wrist watch as a wristlet or watchlet and only the the term 'watch' when discussing pocket watches. I am sure many of you do own at least one.
If you do not, however, you really can't say you're a student of horology or even claim to be into watches.
