About this product
If you are repairing or building a watch and the movement has given up, the NH35 is one of the most practical replacements to keep on the bench. This is a Japan-made 24-jewel automatic movement with a date window at 3 o'clock, known in the modding world as the NH35A family - the same platform used by countless microbrand and custom builds, which is why parts, hands and stems are easy to source. The key to choosing correctly is the date position: a movement with the date at 3 lines up with dials cut for 3 o'clock, so check your dial and hands before ordering. It is a self-winding design that also hand-winds and hacks (the seconds stop when you set the time), which makes setting quick and precise. Fitting one is not a beginner job: you need the right case, dial feet, hands and stem, plus basic watchmaking tools and a dust-free space. If in doubt, note your case's movement number and match it exactly.
