NH35 Movement

The NH35 is one of the most commonly encountered movements in the watch-modification hobby. Its popularity means there are many cases, dials, hands and other components designed around it.

Why beginners like it

The large aftermarket ecosystem makes it easier to find compatible components. It is therefore possible to plan an entire watch around the movement before purchasing the individual parts.

Check compatibility first

Never assume that two parts will automatically fit together simply because they are advertised for watch modding. Always check the movement specification, case compatibility, dial feet, hand sizes and crown/stem arrangement before ordering.

NH36 Movement

The NH36 is closely related to the NH35 but is commonly selected for day/date configurations. If your design includes a day display, the NH36 may be the more appropriate choice.

As with any movement, the rest of the build needs to be designed around the specific movement rather than selected independently.

Before Buying a Movement

A low headline price isn't necessarily the best deal. Look at the complete listing, seller information, movement specification and whether the item includes the components you actually need.

For beginners, buying the movement first and then selecting compatible parts around it can be easier than purchasing a collection of unrelated components.
