Quartz Clock Movements, Motors, Hands, Dials & Clock Kits - USA Manufacturer Since 1971

ClockParts.com is a family-owned manufacturer and distributor of quartz clock movements, motors, hands, dials, inserts, and complete DIY clock kits, based in Culver City, California. Since 1971, hobbyists, woodworkers, and professional clock repairers have relied on us for replacement clock mechanisms, wholesale pricing, and free technical support by phone, video, and email. Whether you are repairing a family heirloom or building an 18-inch-hand wall clock from scratch, we manufacture the exact component you need.

Clock Movements & Motors

Our clock movements line covers every project size and style: mini AA-battery quartz movements for compact builds, standard C-cell movements with extended battery life, high torque motors for oversized wall clocks, plus pendulum, chiming, tide, 24-hour military, reverse-time, and weather-instrument movements. We also offer nine USA-made movements for projects that carry the Made in the USA label.

Which movement do you need?

  • Standard quartz movements drive minute hands up to 5 inches.
  • C-cell standard movements suit minute hands from 5 to 7 inches and deliver the longest battery life.
  • High torque movements are required for minute hands over 7 inches and drive hands up to 18 inches.
  • Tide movements complete one revolution every 24 hours and 50 minutes to track lunar tide cycles.

Auto Set Movements - Automatic Daylight Saving Time Without a Radio Signal

Our Auto Set movements adjust automatically for U.S. Daylight Saving Time using a pre-programmed chip accurate through the year 2099 — no radio broadcast required. Traditional atomic movements depend on receiving an AM time signal, and their receiver modules are notoriously unreliable indoors, in metal cases, or far from the transmitter. The Auto Set motor eliminates that failure point entirely: build your clock, hang it anywhere, and the spring and fall time changes happen on their own.

High Torque Movements for Large Wall Clocks

Building a statement wall clock? Our high torque clock movements supply the extra power needed to drive minute hands from 6 up to 18 inches. Note one important compatibility rule: hands made for German high torque movements use different mounting-hole sizes than hands for our other high torque motors, and the two are not interchangeable. If you are unsure which pairing you need, our technical support team will match the movement, shaft length, and hand set for you before you order.

Clock Hands

Hands are both functional and cosmetic, and the right set defines your clock’s character. Our clock hands selection includes hour, minute, and second hands in a full range of lengths, shapes, and finishes – including Seiko continuous-sweep second hands, an antique reproduction series, and dedicated hands for German high torque movements.

Clock Dials

Choose from round and square clock dials in metal, plastic, and tin, including antique reproduction faces, 24-hour military dials, and reverse-time dials for barbershop-style mirror clocks. We stock the most popular dial sizes on the market alongside specialty faces you will not find elsewhere.

Clock Inserts (Fit-Ups)

Clock inserts, also called fit-ups, are complete self-contained clock units — hands, dial, lens, and bezel in one component — that drop into a pre-drilled hole in your case. They are the fastest way to finish a woodworking, resin, or craft project with a professional clock face. Our new premium insert line raises the standard for both quality and design variety.

Clock Kits & Assortments

Our clock kits bundle everything a project needs. The most popular is our large wall clock kit, which supports hands spanning up to three and a half feet and ships with Arabic or Roman numeral sets, complete instructions, and free telephone support.

Clock Accessories & Tools

The right clock accessories turn a decent build into a great one: mounting hardware, batteries, pendulum parts, display stands, and specialty tools. Our minute hand nut driver makes tightening the minute hand nut simple and quick – and we will even show you how to make your own hour hand tool.

Clock Repair Made Simple

Skip searching for “clock repair near me.” In most battery clocks, the entire mechanism can be replaced in minutes with a new quartz movement — usually for less than the cost of a repair-shop visit. Measure your dial thickness, choose the matching shaft length, pick your hands, and install. Our video library, blog, and Technical Support Center walk you through every step, and our Ask the Clock Expert team answers questions directly.

Frequently Asked Questions

What size clock movement do I need for my hands?

Standard quartz movements drive minute hands up to 5 inches. C-cell movements handle 5 to 7 inch hands with the longest battery life. Minute hands over 7 inches require a high torque movement, which drives hands up to 18 inches.

How do Auto Set movements differ from atomic movements?

Auto Set movements adjust for U.S. Daylight Saving Time using a chip pre-programmed through 2099, so no radio signal is needed. Atomic movements must receive an AM broadcast time signal, which often fails indoors or in metal clock cases.

How do I choose the correct shaft length?

Measure the thickness of your dial and mounting surface. The threaded shaft must pass fully through the material with enough thread remaining for the mounting nut and hands. Our Technical Support Center can confirm the right shaft for your dial.

Are all high torque clock hands interchangeable?

No. Hands for German high torque movements use different mounting-hole sizes than hands for other high torque movements, and the two are not interchangeable.

What is a clock insert or fit-up?

A clock insert (fit-up) is a complete self-contained clock — hands, dial, lens, and bezel in one unit — that fits into a pre-drilled hole in a clock case or craft project.
