Inside is the proven Seiko NH35 automatic movement. You assemble the watch yourself using the included components, watchmaking tools and step-by-step video guidance — no previous watchmaking experience required.

Gift of the Year 2026 Nominee
Seiko NH35 automatic movement
A proven and reliable Japanese automatic movement that powers the watch you assemble yourself.
Each Horologic watchmaking kit includes:
The movement arrives assembled and the crown stem is already cut to the correct length.
For full shipping, delivery and return information, refer to our Shipping & Returns policy.
Your Horologic kit arrives with the components, tools, and guidance needed to assemble your own automatic watch at home.
Add a second strap
Your kit includes the above displayed strap. Add an extra strap or bracelet to change the character of your watch after the build.
NH35 automatic movement
Powered by a mechanical mainspring rather than a battery, the NH35 winds automatically with the movement of your wrist and can also be wound by hand.
When fully wound, it keeps running for approximately 41 hours—even when you’re not wearing it.
The movement arrives fully assembled. You fit the dial and hands, secure it inside the case, and finish a watch you’ve put together yourself.
The kit is designed for careful beginners. You do not need prior watchmaking experience, but the build requires patience, focus, and a steady hand. Follow the guidance step by step and take your time.
If you enjoy careful hands-on work and following detailed instructions, this kit is designed for you.
REAL WATCH ASSEMBLY, MADE APPROACHABLE
The mechanical movement arrives fully assembled and the crown stem is already cut to the correct length. You take it from there — fitting the dial and hands, casing the movement, installing the crown, closing the case and attaching the strap or bracelet.
It's genuine watch assembly, using real watchmaking tools and components, but designed so that you can enjoy the process without previous experience.
Position the dial, find midnight and carefully install each of the three hands.
Place your completed movement into the case, refit the pre-cut crown and stem, and secure the caseback.
Attach the strap or bracelet, set the time and date, and put on a watch you assembled yourself.
Horologic is made for people who want to give more than another object. The experience of building the watch becomes part of the story behind it — making it especially meaningful for birthdays, Father's Day, Christmas, retirements, or anyone who loves mechanical things.
