The Clifton Baumatic
Created in cooperation with the Manufacture Horlogère ValFleurier and the Richemont Research & Innovation teams, the Baumatic
The new hairspring is endowed with the TWINSPIR
Combined with a newly shaped variable-inertia balance wheel, it delivers the following benefits:-
• Improved accuracy of the movement various positions and over the long term
• Reduced sensitivity to magnetism
• Greater resistance to small impacts and repeated vibrations
Silicon facilitates longer maintenance service intervals for both the watch and its movement.
• The hairspring
• The anchor
• The escape wheel
of the Baumatic
Requiring very little lubrication, the new high-performance escapement equipped with
Its new design based on complex shapes serves to:-
• Drastically reduce losses relating to friction = increase efficiency
• improve torque transmission between the components
• Thus ensure 30% higher autonomy
The advent of the Baumatic
A Baume & Mercier watch equipped with the Baumatic
Numerous objects emit magnetic fields liable to disturb the smooth running of a mechanical watch. A number of mechanical watches returned to watch brands’ after-sales service departments display symptoms relating to the effects of magnetic fields, the two most frequent being a movement that has stopped or a loss of precision. These flaws are due to the fact that certain components – notably the hairspring made from a ferromagnetic alloy – become magnetized.
According to the 2002- ISO 764 (NIHS 90-10) standard, a watch is considered antimagnetic if it is able to withstand a magnetic field of 60 Gauss (4,800 A/m) while maintaining a precision of +/- 30 seconds per day. The Baume & Mercier Clifton Baumatic
There are two ways of counteracting the effects of magnetism: either protecting the movement by means of a magnetic shield; or tackling the problem at its roots by using antimagnetic materials. Thanks to the use of silicon and non-ferromagnetic elements for the two particularly sensitive parts of the movement, the regulating organ (including the hairspring) and the escapement system, BaumaticTM movement achieves exceptional performance.
The power reserve of a standard watch movement ranges from 40 to 70 hours when it is fully wound. The Baume & Mercier Baumatic
This gain in efficiency is due in equal measure to three elements:
- 1/3 of the improvement relates to the barrel (optimized size and the material used for the spring)
- 1/3 of the improvement relates to the escapement (silicon anchor and escape wheel, POWERSCAPE TM technology for optimized geometry)
- 1/3 of the improvement relates to the use of silicon for the hairspring (TWINSPIRTM technology, increased quality factor, new geometry of the variable-inertia balance wheel)

Mechanical watches are not always very accurate, and are even less so when their power reserve runs low. Their precision deteriorates still further when the movement has to draw upon a dwindling amount of energy. Watches boasting good precision (-4/+6 seconds/day) are chronometer-certified by the Swiss Official Chronometer Testing Institute (COSC). Acting on the precision of watch mechanism makes it possible to offer the user enhanced performance.
A standard watch requires regular time-setting, given its daily variation in rate of around 20 to 30 seconds per day.
In addition to its model chronometer-certified by the COSC, all Baume & Mercier series production watches equipped with the Baumatic
The new hairspring equipped with TWINSPIR
In order to preserve the performance and enhance the reliability of our time pieces over extended use, the Richemont Research & Innovation teams focused its research effort on both developing dedicated oils so as to maintain optimal lubrication conditions and devising new test procedures to assess long term performance under relevant stress conditions.
Through fine understanding of wear conditions, intense laboratory investigation and modeling, lubricants formulation have been adjusted to fulfill their long lasting mission under severe strains. Each key function is being thoroughly tested with new procedures and test benches developed specifically to account for strains that our watches encounter. These stress tests not only include thousands of repetitive cycles to simulate more than 10 years of intense use, but also newer tests reflecting more accurately todays activities and lifestyles.
The service and maintenance cycles for all Baume & Mercier watches equipped with the Baumatic
A watch movement is a complex mechanism comprising numerous mobile miniature components. Their perpetual interaction results in friction and wear. The latter can be minimized by lubrication which is a sensitive issue in any watch movement. Various oils with distinctive properties are used to lubricate a watch movement, according to the given function (winding mechanism, balance wheel pivot, escapement, gear train).
The ageing of lubricants is one of the causes resulting in disturbances to the smooth running of a movement, and thus one of the reasons why watches are returned for service. Acting on lubrication and the quality of different oils serves to decrease the frequency of watch service and maintenance interventions.
With their refined, porcelain-like finish, the five new models in the Clifton Baumatic
Topped with a domed sapphire crystal, the minute track – in anthracite gray or white – follows the perfectly proportioned curves of the 40 mm polished/ satin-finished steel case. Water-resistant to 50 meters, the transparent case back reveals the new Baumatic
This timepiece, attaches to the wrist with an alligator strap that fastens with a pin buckle. The strap is easy to change without the need for a tool, and comes in dark blue, deep black or warm brown for the two-tone version. A five-row bracelet in polished/satin-finished steel, which fastens by means of a triple folding buckle with security push-pieces, is also available to complement this line of contemporary watches.
