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.
