A mechanical watch movement is a complex mechanism comprising numerous mobile miniature components. Their perpetual interaction results in friction and wear ultimately influencing the smooth running of the movement. This is one of the reasons why watches have to be returned for regular service.

The new Clifton Baumatic from Baume & Mercier with the maison?s first in-house mechanical self-winding calibre, the Baumatic BM12-1975A, is offering lengthened maintenance service intervals beyond the generally recommended three to five years. Additionally, the new Baumatic is resistant to at least 1500 Gauss without residual effect and comes with a convenient five-day power reserve with full chronometer precision (-4/+6 seconds per day over the entire 120 hour power reserve). Baume & Mercier?s Clifton Baumatic is enhancing the user experience in four key areas:

More autonomy with five-day power reserve
Enhanced accuracy performance
Resistance to magnetic fields
Great durability

The Challenge:
Like a car, your mechanical watch needs to be serviced now and then. If a watch is worn sparingly, the interval can be longer, but if constantly worn, owners should let elapse between servicing. Which is why most watch manufacturers recommend servicing every three to five years.
The new Baumatic offers considerably longer intervals between services, limiting the time without actually having the watch.
The Response:

Through fine understanding of wear conditions, intense research and ...
