Motion & ratios
Count gear teeth, compare connected wheels, and trace how rotation passes through the mechanism.
STEM clock kits for schools, camps & makerspaces
Build a real
mechanical clock.
Bring gears, spring energy, and pendulum motion into the classroom with the Hermle Lakin Clock Kit. Students assemble a working, hand-wound desk clock they can see, study, and use.
For schools, camps, clubs, and homeschool groups.

From components to a working clock
A mechanical clock building kit
with engineering you can see.
The Lakin's open skeleton design keeps the mechanism visible. Students can follow how the parts work together as they build the clock, then observe the movement while it runs.
What students assemble
The project includes gears and the mainspring, movement plates, pendulum, dial and hands, aluminum pillars, acrylic plates, and hardware. The kit also includes a screwdriver, wrench, winding key, and clock oil.

Ideas for STEM & STEAM learning
Build it. Observe it.
Investigate it.
The learning can continue after the last screw is in place. The Lakin's open movement lets students examine the gears, watch the pendulum, and connect the parts they assembled to a working mechanism.
Use the clock as a starting point for questions about motion, energy, and measurement. Adapt the investigation to your students and your course.

Stored energy
Discuss how winding stores energy in the spring and how that energy drives the clock.
Rhythm & timing
Observe the pendulum, measure its swing period, and explore its role in mechanical timekeeping.
Test & record
Compare the clock with a reference time, record error, and discuss the adjustments described in the instructions.
These are suggested learning activities. Hermle provides assembly instructions and a build video; educators can adapt the project to their own curriculum and learning goals.

Does the kit include a complete STEM curriculum?
Hermle provides illustrated assembly instructions and an assembly video. The learning ideas on this page are suggestions for educators to adapt; a complete lesson curriculum is not included with the kit.
Is this a working mechanical clock?
Yes. The assembled Lakin is a hand-wound, time-only mechanical desk clock with a pendulum and exposed skeleton movement. It does not chime.
What ages or grade levels is it intended for?
Hermle describes the kit for upper elementary, middle, and high school classrooms. Educators should review the instructions to assess the supervision and skill level their group needs.
How long does the classroom build take?
Plan the time around your students' experience, supervision, and any learning activities you add. Review the assembly video and consider a teacher practice build before setting your class schedule.
Can schools, camps, and clubs order multiple kits?
Yes. Request a group quote with your approximate quantity and needed-by date. We'll confirm pricing, shipping, and availability for your project.
Can I order one kit before planning a class?
Yes. Visit the Lakin product page for the current price, availability, and ordering options. A practice build can help you plan how to introduce the project to your group.
Are kits available for a specific semester or camp date?
Please contact us with your quantity and required date. Group availability and delivery timing need to be confirmed before you schedule the build.
