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
No Compromise on Quality
Our new Clifton Baumatic watches are equipped with the Baumatic BM13 automatic calibre and offer the following advantages:
Power reserve: 120 hours or five days
Anti-magnetism: resistance to the magnetic fields encountered in daily life – which may cause disruption or result in a movement suddenly stopping
Chronometric accuracy: COSC certification with a variation of -4 to +6 seconds per day
Reliability: these models should not require maintenance service before 5 to 7 years whereas 3 to 5 years are recommended for a traditional watch
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.
