Seiko movement experience

Extensive experience with common Seiko movements.

Seiko movements are not interchangeable. A 7S26 does not hand-wind from the crown, a 4R36 does, and a 6R35 has different power-reserve expectations. Those details matter when a watch stops, loses time or will not stay wound.

We use the caliber, symptoms and physical condition of the watch to decide whether it needs regulation, a targeted repair, full service or movement replacement.

If you know the movement, use it. If you only know that the watch is fast, slow, stopped or will not wind, start there.
