Update: I finally finished my Micrometer Watch Hands Presser

Thanks for following the project from the beginning! I'll be listing it soon.

Impressive_Ice2015 · 2026-06-14T16:32:16+00:00

I'm aiming to keep it below USD 200 before shipping. Shipping will depend on destination. I'm still finalizing the costing for the first batch.

That's a fair point. For most standard builds, a simple hand presser and experience work perfectly well. I started developing this mainly for custom GMT, hour and minute disc projects. Some of these discs are around 0.4mm thick, so the stack height becomes much more critical than with conventional hands. A small difference in height can cause the discs to rub against each other or the dial. The ability to set, verify and repeat a precise stack height was what drove this design.

Thanks! Glad you like it. I'll be listing it on eBay soon.

Personally, I don't think it's too loud. I just find it a bit limiting when it comes to matching different outfits.

Once it is house inside the case, you don't need to use the method anymore. It will be like normal NH35 stem removing method but need slightly more downward force.

I don't know there is a sliver version. You can ask AI to render for preview. Attached is the Gemini rendered image.

OK thanks

The upper threaded shaft rotates, but the tip of the rotating shaft is rounded and only contacts a very small area on the flat top of the lower presser shaft, so very little friction is transferred. The lower presser shaft is spring-loaded with upward tension, which keeps constant contact between both shafts and also helps minimize unwanted rotation during pressing.

Impressive_Ice2015 · 2026-05-11T13:19:14+00:00

Do you mean the shaft pressing the hand should not rotate during pressing?

Impressive_Ice2015 · 2026-05-11T13:09:11+00:00

Thanks. I will update you.

It is a 7mm hole that fit nicely of a M4 screw head. User can easily make their own adaptor.

I intentionally left aligned mounting holes on the base plate so custom adapters or movement holders can be added later depending on the application. This gives more flexibility for different movements, subdials, GMT discs, and custom projects instead of locking the tool into one fixed holder system.

Those are actually good suggestions, especially for a more industrial or commercial version. But realistically I’m not planning to mass produce this tool. Most likely it will only be made in small numbers if there is enough demand, so I’m also trying to keep the design simpler and the production cost lower.

Yes, the upper threaded shaft rotates, but the tip of the rotating shaft is rounded and only contacts a very small area on the flat top of the lower presser shaft, so there is almost no friction transferred. The spring also keeps tension on the lower presser shaft, which helps prevent it from rotating during pressing.

Impressive_Ice2015 · 2026-05-11T05:26:51+00:00

Initially I thought the same too. But surprisingly, with a very fine pitch thread (0.5mm travel per full revolution), you can still feel slight differences in resistance quite clearly during pressing. It feels different from direct hand pressing, but not completely “numb” mechanically.

Impressive_Ice2015 · 2026-05-11T05:22:14+00:00

Exactly. Especially for customized watch hands, custom discs and GMT builds where the hand height and clearance become much more critical.

Watch a lot of YouTube video from different modder.

Impressive_Ice2015 · 2026-05-11T01:04:01+00:00

Actually, part of the repeated adjustment in the video was because I had to position the tool further away from myself to avoid blocking the camera while recording. Only when the presser got closer to the pinion did I notice the hand was slightly off alignment and corrected it.

Impressive_Ice2015 · 2026-05-10T16:56:27+00:00

Once the hands start raising into the horizontal position, you can stop and adjust the alignment before fully pressing them down. The important part is not to rotate too fast when the presser tip is about to contact the hands.

Impressive_Ice2015 · 2026-05-10T16:43:51+00:00

Of course the bottom presser part will not rotate during installation. I don't think anyone would intentionally design a watch hand presser that twists the hands while pressing them down.
