	A feature that shows when the watch will soon need a new battery or winding. A battery reserve indicator on a quartz watch informs the wearer when the battery is low. Often this is indicated by the seconds hand moving at two or three-second intervals. Seiko's Kinetic watches are quartz watches that do not have a battery (see Kinetic).

	*'''Super Compressor'''		*'''Super Compressor'''
	A watch case patented in 1956 by Ervin Piquerez SA (EPSA) and manufactured by them for almost two decades. Super Compressors can be identified by their twin crowns and internal rotating timing ring. EPSA’s logo was a stylized diving helmet and could be found either on the outside or inside of the caseback. The crowns typically were without a watch company’s logo but were cross-hatched.

			*'''Tourbillon'''
			delicate cage of steel or titanium holding the balance and spring, negating the effects of gravity by rotating approx once a minute
			*'''TwentyFour Hour Watch'''
			where the hour hands rotates just once every 24 hours. Used in military models initially but now seen on GMT watches and some perpetual calendars
	*'''Tuning Fork Movement'''		*'''Tuning Fork Movement'''
	A now-obsolete technology patented by [[Bulova]] that centred on a small steel tuning fork with copper wire coils on each tine that could be induced to resonate typically at a reliable 360 Hz when attached to a battery powered transistor. The output from the tuning fork is used to drive an index mechanism that records time. The frequency used is not ultrasonic (compare with quartz movements) so the watches produce a quiet noise that sounds like a hum, hence the colloquial name for them: ‘hummers’.

	*'''Rattrapante Chronograph'''		*'''Rattrapante Chronograph'''
	Also called a double chronograph or split-seconds chronograph, this adds an additional seconds hand and pusher to the standard chronograph function. The additional seconds hand moves in sync with the standard seconds hand, but stops when the extra pusher is depressed, allowing the user to record two times at once (eg individual versus accumulated lap times). On a second depression of the extra pusher, the additional hand is released and synchronises immediately once again with the continuous seconds hand (hence rattraper, meaning to catch up, recover, recapture).
