Baume & Mercier’s new Clifton Baumatic: Protected against Magnetic Fields.

Various objects in our everyday life constantly emit magnetic fields that can potentially influence the accuracy of a mechanical watch. The Clifton Baumatic from Baume & Mercier with the maison’s first in-house mechanical self-winding calibre, the Baumatic BM12-1975A, is offering significantly better protection against magnetic fields, without having to hide the state-of-the art movement in a protective soft iron cage.

The new Baumatic is resistant to at least 1500 Gauss without residual effect. – That’s 25 higher than the current ISO 164 (NIHS 90.10) norm. Additionally, the BM12-1975A comes with a convenient five-day power reserve with full chronometer precision (-4/+6 seconds per day over the entire 120 hour power reserve), and considerably longer intervals between services.

Baume & Mercier’s Clifton Baumatic is enhancing the user experience in four key areas:

  1. More autonomy with five-day power reserve
  2. Enhanced accuracy performance
  3. Resistance to magnetic fields
  4. Great durability

The Challenge:

Magnetic fields (for example from a clasp on a purse, cell phone or a tablet protective cover) are one of the most frequent reasons for a movement that has stopped or experienced a sudden loss of precision.

The Response:

The Clifton Baumatic’s new movement offers significantly enhanced protection and accuracy at the same time: The Clifton Baumatic uses silicon and non-ferromagnetic elements for the two most sensitive part of a mechanical movement, the regulating organ (including the hairspring) and the escapement.

The five different versions of the new Clifton Baumatic are available from September 2018 on, with prices starting at $2,750.
