H. Moser & Cie. Venturer Small Seconds XL Paramagnetic Limited Edition

Independent Swiss luxury watch brand H. Moser & Cie. presents Venturer Small Seconds XL Paramagnetic, a world premiere timepiece equipped with PE5000 paramagnetic hair spring developed by Precision Engineering AG.

Together with sister company H. Moser & Cie., Precision Engineering AG has created a new alloy, PE5000. Shock resistant and paramagnetic, this material will be integrated for the first time in a very special edition, the Venturer Small Seconds XL,  in a limited edition of 10 pieces. H. Moser Owners may acquire these watches and take part in a series of tests to confirm the chronometric performance of this escapement of the future.

An alloy of niobium and titanium, PE5000 has highly valuable characteristics for the regulating organs of mechanical watches. As a paramagnetic material, it is extremely resilient and has such remarkable elastic properties that a hairspring made from this alloy is not affected by impacts. This is an invaluable asset for the oscillator of a mechanical watch, constantly in motion and subject to significant constraints.

The alloy of niobium and titanium has a great affinity for oxygen, which results in the challenge of greater wear on tooling; however, the manufacturing processes overall are similar to those for producing traditional hairsprings, in all steps taken to shape the material. As a producer of regulating organs, Precision Engineering has the expertise needed for this new technology.

PE5000 represents a very interesting alternative to silicon, which is also non-magnetic and shock resistant, with the disadvantage of not allowing any adjustments. Niobium-titanium, in contrast, can be adjusted by the watchmaker to optimise the watch’s performance if necessary. Precision Engineering joins the few manufacturers capable of producing paramagnetic escapements, a major advantage in the Swiss watch industry. With a new label, synonymous with quality and precision:  Precinergy.

The first client for Precision Engineering, H. Moser & Cie. has the premiere of their niobium-titanium hairsprings. The Manufacture also joined Precision Engineering in watch movement tests in a zero gravity environment to test the properties of PE5000. For the first series of watches with this paramagnetic hairspring, H. Moser & Cie. chose the Venturer Small Seconds XL. The bezel, refined and elegant, opens onto the convex dial, enhanced by the curved sapphire crystal. And to add to this unique series, a new dial is introduced just for this exclusive watch: a deep blue fumé. Blue, a colour synonymous with quality in traditional watchmaking, is also used in the Balance Bridge and balance wheel, thanks to a special finish that gives a depth to the escapement.
