Five Seiko calibres. Chosen for their reliability, their accuracy and because they can be serviced anywhere in the world.

Why Seiko Instruments.

Seiko movements are made in Japan by Seiko Instruments. They power watches from €200 to €2,000 all over the world. Their robustness is well documented and they can be serviced anywhere. A watchmaker in any country can work on an NH35. That makes it the most sensible choice for an affordable watch built to last.

Every movement is tested in 5 positions on a timing machine in our workshop before shipping.

NH35

Automatic

The most reliable Seiko automatic movement in its price range.

The most reliable calibre in its class. Made by Seiko Instruments in Japan, the NH35 is the reference movement for automatic watches between €200 and €1,000. Robust, accurate and repairable anywhere in the world. The obvious choice for an everyday watch.

NH34

GMT automatic

Seiko's native GMT, with no added module.

NH38

Slim automatic

The purity of the NH35 without the date window.

A version of the Seiko NH35 without the date complication. With no date window, the dial is free for a cleaner design and the case can be slightly thinner. Same reliability, same robustness, a purer look.

NH70

Skeleton automatic

The movement becomes the dial.

The Seiko NH70 shows off its mechanical architecture through a skeleton dial. The gear train, balance wheel and barrel are all visible from the dial side. It's a movement you look at as much as you wear. Same technical base as the Seiko NH35.

VK63

Meca-quartz chronograph

Quartz accuracy. Mechanical feel.

The Seiko VK63 combines quartz accuracy with the feel of a mechanical chronograph. The chrono hand sweeps smoothly around the dial, just like a mechanical movement. The reset snaps back crisply. It's the best chronograph movement under €500.
