Timepiece with overlapping, separately driven analog and mechanical functionality

1 . A dual-powered timepiece for independently displaying time information and driving one or more other timepiece functions, the timepiece comprising:

a case comprising a case interior and a case opening substantially defined by a periphery of a first side of the case;

an analog movement comprising a first timing device within the case interior, the analog movement driving the display of time information in hours and minutes; and

a lever escapement mechanism comprising a second timing device within the case interior, the level escapement mechanism substantially independent from the analog watch movement and driving at least one timepiece function.

2 . The timepiece of claim 1 , the lever escapement mechanism comprising a mainspring driven, balance wheel regulated, lever escapement mechanism.

3 . The timepiece of claim 1 , at least one of the timepiece functions driven by the lever escapement mechanism comprising display of time information in seconds.

4 . The timepiece of claim 3 , the lever escapement mechanism driving the display of second information comprising the lever escapement mechanism driving a sub-second hand that displays a portion of a second.

5 . The timepiece of claim 1 , at least one of the timepiece functions driven by the lever escapement mechanism comprising display of date information.

6 . The timepiece of claim 5 , the lever escapement mechanism driving the display of date information comprising the lever escapement mechanism driving at least one date dial.

7 . The timepiece of claim 1 , at least one of the timepiece functions driven by the lever escapement mechanism comprising display of alarm time information.

8 . The timepiece of claim 1 , the lever escapement mechanism being substantially viewable through the case opening.

9 . The timepiece of claim 1 , a transparent crystal coupled to the case and covering the case opening.

10 . The timepiece of claim 1 , the case configured to accommodate quartz movement as the analog movement.

11 . The timepiece of claim 10 , the analog movement comprising a battery driven, quartz integrated circuit.

12 . The timepiece of claim 11 , the battery comprising a litho battery.

13 . The timepiece of claim 11 , the quartz integrated circuit further driving an Electro-luminescent (EL) backlight.

14 . The timepiece of claim 11 , the quartz integrated circuit further driving a Liquid Crystal Display (LCD) display.

15 . The timepiece of claim 11 , the quartz integrated circuit further driving an Organic Light Emitting Device (OLED) display.

16 . The timepiece of claim 1 , the analog movement driving the display of time information comprising the analog movement driving an hour hand and a minute hand that display a time of day in hours and minutes respectively.

17 . The timepiece of claim 1 , the analog movement driving the display of a time information comprising the analog movement driving an hour disk and a minute disk that display a time of day in hours and minutes respectively.

18 . The timepiece of claim 1 , the analog movement at least partially hidden by the lever escapement mechanism and the timepiece further comprising an analog display comprising an hour hand, a minute hand, and an interior bezel, the interior bezel symmetrically aligned with the case opening and further comprising a plurality of markings that facilitate reading the time information indicated by the position of the hour hand and the minute hand; and

wherein the analog movement comprises a battery, the first timing circuit, a hand-moving assembly, and a stem and crown assembly, the hand-moving assembly extending from the analog movement through the lever escapement mechanism and coupling to the hour hand and the minute hand of the analog display.

19 . The timepiece of claim 1 , the timepiece comprising a wristwatch.
