Watches & Timepieces

23 products, each exploded into a recursive bill of materials. Open one and keep clicking down to the bolts.

Analog Alarm Clock A battery-powered bedside clock: a quartz movement steps the hands, and a cam-triggered contact fires a motor-driven hammer against twin bells at the set time. 38 parts · 6 subsystems

Carriage Clock A small spring-driven travelling clock in a glazed brass case with a carrying handle: a platform lever escapement keeps time independent of position, and a strike/alarm train sounds the hours on a gong. 49 parts · 6 subsystems

Chess Clock A two-faced game timer: a rocker bar or paired buttons stop one player’s countdown and start the opponent’s, with a digital control board enforcing time controls such as increment and delay. 47 parts · 6 subsystems

Chronograph Watch A mechanical wristwatch with an integrated stopwatch: a column-wheel chronograph layer couples to the base movement on demand to drive a sweep seconds hand and elapsed-time counters. 63 parts · 6 subsystems

Cuckoo Clock A carved wooden weight-driven pendulum clock: a brass two-train movement that, on the hour, opens a door and works a bellows-and-pipe cuckoo while striking a gong, all driven by pine-cone weights on chains. 79 parts · 9 subsystems

Digital Desk Clock A mains- or USB-powered bedside clock: an MCU with a crystal-backed RTC drives a seven-segment LED display, sounds alarms, and optionally syncs to a longwave time signal. 33 parts · 7 subsystems

Dive Watch An ISO 6425 wristwatch built for saturation in salt water: a self-winding mechanical movement in a sealed case, with a one-way timing bezel and a screw-down crown. 34 parts · 6 subsystems

Flip Clock A split-flap clock: a continuously geared motor rotates hour and minute drums whose hinged flaps are held back by a detent and released one at a time to flip the displayed digits. 119 parts · 6 subsystems

GPS NTP Time Server A rack-mount stratum-1 time source: a GNSS timing receiver disciplines an ovenized oscillator, and a network processor serves NTP and PTP to thousands of clients. 37 parts · 7 subsystems

Grandfather Clock A mechanical longcase pendulum clock: weight-driven brass movement with three gear trains (time, strike, chime), an anchor escapement, a seconds-beating pendulum, and a tall wooden case with a moon-phase dial. 168 parts · 9 subsystems

Mantel Clock A spring-driven shelf clock: three keywound trains keep time, chime the quarters on tuned rods, and strike the hours, all inside a wooden case. 46 parts · 7 subsystems

Marine Chronometer A precision spring-driven timekeeper for celestial navigation: a fusee-and-detent movement kept level on gimbals inside a brass-bound box, reading mean time with a running power-reserve indication. 46 parts · 7 subsystems

Mechanical Metronome A clockwork tempo keeper: a wound mainspring drives an escapement whose inverted pendulum, tuned by a sliding weight, ticks at 40–208 beats per minute. 27 parts · 6 subsystems

Mechanical Watch An automatic (self-winding) mechanical wristwatch: a jewelled caliber driving hour/minute/second hands and a date complication, housed in a water-resistant case on a bracelet. 58 parts · 4 subsystems

Pocket Watch A hand-wound mechanical pocket watch: a jewelled lever movement wound and set from the crown, housed in a hinged hunter case behind a domed crystal, read off a Roman-numeral dial. 35 parts · 5 subsystems

Quartz Watch An analog quartz wristwatch: a stepper-motor movement driven by a 32 kHz crystal turns hour, minute, and second hands over a dial. 76 parts · 6 subsystems

Radio-Controlled Atomic Clock A quartz desk clock that disciplines itself to a national time signal: a low-frequency radio receiver decodes the WWVB/DCF77 broadcast and corrects a stepper-driven analog hand set and an LCD, all run from a single lithium cell. 130 parts · 8 subsystems

Railway Station Clock A double-faced platform slave clock: a master clock sends minute impulses down a two-wire line, and a polarized stepping movement advances large dials on both sides. 43 parts · 7 subsystems

Skeleton Clock A clock built to be seen working: pierced brass plates expose the fusee drive, going train, and escapement, all protected under a glass dome. 35 parts · 7 subsystems

Tower Clock A weight-driven turret clock: falling weights power separate going and striking trains, a gravity escapement and long pendulum keep the rate, and motion works carry time out to large exterior dials and a bell. 76 parts · 8 subsystems

Wall Clock A battery-powered quartz analog wall clock with a stepper-driven gear train sweeping three hands across a printed dial. 30 parts · 6 subsystems

Watch Winder A motorized cabinet that slowly rotates an automatic watch in programmed cycles so its self-winding rotor keeps the mainspring charged while the watch is off the wrist. 39 parts · 6 subsystems

World Time Clock A desk clock that shows every time zone at once: a quartz movement drives normal hands plus a 24-hour wheel geared to a ring of city names. 30 parts · 7 subsystems
