SEIKO Movement Holder

The Movement Holder. 70g solid brass. For NH hands work.

Hands are a firm friction fit — they need square, steady pressure, and that starts with a movement that cannot shift. This is our heavy-duty holder for Seiko movements: 70 grams of solid brass with an adjustable pinion supporting the movement from the middle while you press. Version 4 — fitting, finishing and practicality all improved, and the movement now sits flush with the holder.

Sandblasted with stainless steel so the brass doesn't oxidise, and sized to sit snugly under professional hand-setting tools like the Bergeon 8935 and 6012-4-P. Works with or without a press — but the movement never moves.

Steady wins.
70g of brass between your hands and a bent pivot.

Solid brass, 70g.
Heavy enough to stay planted while you work — no chasing the movement around the bench.

Adjustable pinion.
Supports the movement from the centre while hands are pressed — V4 sits the movement flush.

Oxidation-proofed.
Sandblasted with stainless steel so the brass keeps its finish.

Bergeon-ready.
Sits snugly under professional hand setters — Bergeon 8935, 6012-4-P and kin.

Heads up — fit & use

Fits the Seiko movement families listed in Specs — NH, 4R, 6R, 7S and kin. Pairs with a proper hand-setting tool; the holder is the steady half of the job.

Questions, Answered

Everything worth knowing before you build.

Do I need special tools to mod a Seiko?

About eight tools total: case knife, hand-removal lever, hand presser (paired with a brass movement holder), tweezers with plastic or wooden tips, 10×–20× loupe, microfiber cloths, rocket blower.

Why do I need a movement holder?

It clamps the movement so it can't shift while you work on it — most critically when pressing hands, which are a firm friction fit and need square, steady pressure. Setting hands against an unsupported movement risks bending a hand or the pinion it presses onto.

Do you sell crystal presses or hand-setting presses?

No — we stock the three tools on this page and stop there. For a crystal press or a hand-setting press, buy from a dedicated tool supplier or have a watchmaker do the pressing; a crystal in particular should never be seated without a proper press.

What does the spring bar tool do?

It compresses the spring bars that hold a strap or bracelet between the lugs, so you can swap straps without scratching the case. It works on any watch that uses standard spring bars — which is every Lucius Atelier case with lugs — and the spare tips keep it working after the inevitable slip.

Customers praised this precision-machined movement holder for its "high quality" construction and perfect fit with NH35/7S26 movements. The heavy, stable design prevents movement during work, and the 31mm base fits hand press tools perfectly. Shoppers appreciated the adjustable center support and noted it's "a must have" for watch modding. One mentioned price as slightly high.

  • There is no other manufacturer that can surpass the quality of this holder.
  • Solid, high-quality fit & finish. Fits perfectly in the 4-hand presser.
  • Wonderfully made NH35 holder. It fits perfectly and keeps the movement in a perfect spot.

Excellent holder

Very well machined with just the right weight and height. The support **** is easily raised or lowered with the included allan wrench. High quality and recommended to any watch tinkerer.

Great quality and value for money

Tested to fit a 7S26 or NH35 movement perfectly with no wobble or slop. Heavy enough to be stable without being so heavy it's annoying. Came with a decent quality ball-end hex tool to adjust the centre support as well. Very good choice for the price if you work with a lot of Seiko movements. Seems like it will last forever and the Lucius Atelier logo is very tasteful :)

Marvelous and easy to use

I personally don’t have a Bergeron hand setter, so I can’t speak to how well it works with that. However with general use it worked great with my NH35

Perfection

I am a hobbyist watchmaker and build, service, and repair many types of movements. I particularly like Seiko/Hattori movements, as they are true workhorses and can withstand a lot of abuse. Consequently I use them extensively in my builds.

I was looking for a dedicated Seiko movement holder, as the Seiko movements tend to flick out of the universal ones. So I decided to purchase this one.

I received it today and immediately used it for a NH35 that I was finishing service on. I have only one word to describe this movement holder; PERFECTION.

The build quality is superb. The height is perfect for both working and maneuvering. The movement fits snuggly and will not fall. Turning the movement to work on either the dial side or watchmakers side is a breeze. The adjustable center screw is great for providing support when installing hands.

I finished servicing the NH35 and will never again use another movement holder for Seikos.

Best of all, I received a hand written note from Adriel thanking me for my purchase. This small detail exemplifies how humble and professional Adriel is. To take the time to hand write a note gives a true personal touch to the business. Thank you for that!

I would recommend this movement holder to anyone who works on Seiko movements! It is of exceptional quality and craftsmanship.

Perfect for hand setting tools

This movement holder fits perfectly in the Beco Technic hand setting press. It's heavy, yet rotates freely. The movement sits perfectly level and the holder even has a pinion in the middle for extra support.

Brilliant!

I have zero hesitation or mental reservation in sharing publicly the highest praise for this product and this eBay Seller! First struck by the heft of this product—it is solid, high-quality fit & finish, adorned with the Lucious Atelier logo branding. The best part, it fits perfectly in the 4-hand presser for a rock solid base to work.

Seiko NH35 Movement HOlder

The reason I purchased this holder because it has a 31mm base which fits the 4 position watch hand press tool. The movement holders that came with the tool do not hold a NH35 movement and the Aliexpress holders are too wide at the base.

Perfect NH35 holder

This is such a wonderfully made NH35 holder that I am using with a 4 Position Watch Hand Setting machine - it fits perfectly and keeps the movement in a perfect spot. I take delight in wonderfully made items and this is so machined nicely that it delights me out of the box.

I purchased a hand presser and sought mold movement holders for my Seiko movements, however the presser was not suitable, and after replacing the presser I struggled to find the right mold holder, I came across your site and found exactly what I was looking, many thanks.

This holder fits my Bergeon 1996 Hand Press clone EXACTLY.

This 31mm base holder fits my hand press without any measurable slop.
There is no other manufacturer on the entire planet that can surpass the quality of this holder. This is truly a well-thought-out engineering triumph.
YOU WILL NOT FIND A BETTER HOLDER / BASE FOR YOUR HAND PRESS FOR SEIKO 7S26 OR NH-SERIES MOVEMENT WORK.
It's great and affordable!

I'm a gunsmith and hobbyist watchmaker—precision is everything to me.

Your business is appreciated at Lucius Atelier. The owner (Adriel) cares very much for his clients.

Superb V4 Seiko movement holder

Having owned the first V1 movement holder from Adriel, which is still great, this V4 just ensures the movement sits lower. It certainly helps especially when regulating the movement as the stem sits much lower in the groove. All of this ensures that the movement doesnt pop out when adjusting the stud and regulating pin. Really great that it fits perfectly in the Bergeon hand setting tool too.
