Bergeon 4040 P professional movement holder, polyamide frame

Bergeon 4040 P movement holder in polyamide

A universal movement holder with an unbreakable polyamide frame, adjustable and reversible. Suited to calibres from 8 3/4''' to 19''' — that is 20 to 43 mm — it clamps on an outer diameter of 30 to 48 mm. Made in Switzerland by Bergeon.

An antimagnetic frame for the watch movement

Polyamide is a plastic: it carries no magnetic field and cannot pass one to the movement it holds. On a piece just demagnetised, that is one more guarantee the work will hold.

Same logic on the tooling side: antimagnetic tweezers answer the same concern, and a watch demagnetizer treats the piece itself.

A movement holder that goes into the cleaning bath

Polyamide takes the bath. The holder is cleaned with the piece, without prior dismantling or particular precaution — one bench operation fewer to plan for.

Watch calibres from 8 3/4''' to 19'''

That is 20 to 43 mm. The range covers most wristwatch movements, from the small dress calibre to the large diver's automatic.

Movement clamping on an outer diameter of 30 to 48 mm

The clamping figure is not the calibre: it is taken overall, casing ring included. It decides whether the movement fits the jaws, and it always exceeds the bare diameter of the movement.

Reversible movement holder

Turning it over gives access to both faces without refitting the calibre. On a job that means moving from dial to bridges, that is one operation saved and one risk removed.

The most accessible version of the Bergeon 4040

Identical jaws, identical clamping range, same Swiss manufacture: the 4040 P does the same work as the Bergeon 4040 movement holder with a steel frame, at a lower price. It is the way into a tool that benches keep for twenty years.

Around the watch movement holder

The Beco stand of ten watchmaker screwdrivers and the dust blower go with the job. The rest is in watchmaker tool kits.
