This new caliber responds to the real problems encountered by self-winding watches, and provides innovative solutions in four distinct fields:

• Power reserve
• Chronometric accuracy
• Sensitivity to magnetic fields
• Durability

Power reserve

The power reserve of a standard watch movement ranges from 40 to 70 hours when it is fully wound.

All the Baume & Mercier watches equipped with the Baumatic™ movement have a high-performance 120-hour power reserve, i.e. 5 days.

Chronometric accuracy

A standard watch requires regular time-setting, from the instance its daily variation in precision is around 20 to 30 seconds per day.

In addition to its COSC-certified chronometer model, all of the Baume & Mercier watches equipped with the Baumatic™ movement are adjusted to a precision rate of -4/+6 seconds per day and offer a stable level of precision throughout the whole of the power reserve.
 

 
Magnetic fields

There are many effects that may be caused by magnetic fields: the most common being the movement suddenly stopping or a loss of precision.

The Baume & Mercier Clifton Baumatic™ watch is resistant to at least 1,500 Gauss, a resistance 25x higher than the current ISO norm.

Durability

A watch movement is a complex mechanism comprising numerous mobile miniature components.  Their perpetual interaction results in friction and wear, which can be minimized by lubrication, a delicate issue in any watch movement.

The quality of the various lubricants for the Baumatic™ movement make it possible to prolong the maintenance service intervals beyond the generally recommended five years.
