Watches that continue to operate (with deviations under particular
limits) when exposed to the influence of magnetic fields of a certain
strength may be called anti-magnetic according to DIN.
A unique rubberised mount which encloses and secures the watch
movement in a case connected to the outer case solely by a flexible
ring. Shocks to the watch allow the movement case to float and absorb
much of the shock energy.
This relates to a watch where the mainspring is wound by harnessing
the movement of the wearer’s arm/wrist. These movements cause the rotor
(an oscillating weight) to rotate and wind the mainspring.
The balance works in combination with the balance-spring to regulate
the rate of a mechanical watch. The balance usually comes in the form of
a three-spoke wheel whereby oscillations are translated into the
movement of the pallets via a small ruby pin (the impulse pin). In
classical watch movements, the balance oscillates at a rate of 5 beats
per second (bph), the equivalent to 18,000bph. To improve the precision,
modern wristwatches have an increased rate of 19,800, 21,600, 28,800 or
sometimes 36,000bph. In quality wristwatches, the balance is made of an
alloy called Glucydur, a mixture of copper and beryllium and iron which
has a hardness of 380 Vickers, allowing it to be carefully regulated
and riveted in position. Temperature also has very little effect on this
A spiral of ribbon-shaped metal, coiled 12 to 15 times, that ensures
that the balance oscillates at a regular rate. The balance spring is
securely fastened to the balance’s axis of rotation and delivers the
braking and acceleration energies required to keep the balance rotating.
Nivarox is the special alloy used for quality springs. Nivarox is an
alloy that doesn’t rust, and is immune to magnetism and temperature.
This is a special stage in the case production, in which the metal is
bombarded with electrons to give the stainless steel a dramatically
increased hardness and scratch resistance. On the Vickers scale of
hardness, B-EBE2000 produces a watch case with a value of 2000, which is
approximately seven times that of the normal stainless steel used for
Every year prestigious watch and Jewellery houses celebrate and
showcase their new launches, creations and innovations at Baselworld,
Switzerland. The show attracts press, retailers, and consumers and is
widely known as the most important premier event in the watch industry
A term used to describe the form and/or size of a movement and often specifying the type of movement.
This pertains to a model of watch that displays hours, minutes and seconds, together with a mechanism for measuring elapsed time by means of a central chronograph hand which records seconds and totalisers for the minutes and hours.
A chronometer defines the accuracy and testing over an official
15-day series of tests by the official Swiss Chronometer testing
institute, over a range of temperatures and five physical positions. The
average daily deviation rate of the movement must be between –4/+6
seconds per day and only then can the movement be awarded as a
chronometer and ultimately receive a certificate issued by the COSC.
Contrôle Officiel des Chronomètres is an independent non profit
testing body for watches manufactured in Switzerland to defined
Black Diamond-Like Coated hardened stainless steel.
A convex pane of clear glass-like material (usually artificial sapphire) covering a watch’s dial.
Energy from the mainspring is retained by the escapement to help
control the gear train. At the same time the escapement provides further
energy to the balance spring where unavoidable losses due to friction
are compensated. Contemporary wristwatches usually contain the pallet
escapement which consists of the escapement wheel and its pinion.
A unique mechanism developed by Bremont consisting of a soft-iron
housing in which the movement is cushioned, routing magnetic fields
around the movement.
The Flyback function allows an ongoing time measurement to be
interrupted and a new one to be started instantaneously by merely
pressing a button. It combines three steps – stop, reset to zero and
restart – into one. In chronographs without the Flyback function, these
three steps must be executed consecutively. This function was originally
invented in the early days of aviation. The concept behind the complex
function dates back to the era when flight-deck crews still navigated
with maps and watches and often had to react very quickly to suddenly
Greenwich Mean Time (GMT), or Zulu time (Z). is used as the standard
clock of choice for international reference time in communications,
military, aviation, maritime and other activities that cross time zones.
A shock absorption system used in pocket and wristwatches.
A device which can be used to set the rate of a watch by changing the
effective length of the balance spring in the oscillation system.
To minimise friction in the most important bearings, jewels are fixed
to the anchor pallets and ellipse. A movement with a large number of
jewels does not necessarily mean that the movement is of particularly
Watches that are powered by a mainspring whereby the oscillating
system runs purely on a mechanical basis, e.g. balance or pendulum.
This scale was devised to divide the whole spectrum of hardness using
a scale of 1 to 10. “1” stands for a very soft material (talcum) and
“10” for the hardest material (diamond).
This can occur when a watch is subjected to a magnetic field. A
magnetic field can emit from a variety of different sources in day to
day life. Computer hard drives, medical equipment, large speaker
systems, refrigerator doors, magnetic tablet cases, mobile phones,
magnetic catches on handbags to name a few can all emit magnetic fields.
Magnetism may lead to excessive rate gain which can cause a watch to
run fast or stop entirely. Magnetic fields do not cause permanent
damage and minor intervention only is required to return your Bremont to
it’s usual excellent standard.
The maximum amount of time over which a mechanical movement can continue to run after its mainspring has been fully wound.
Patented rotating bi-directional Roto-Click® inner bezel is an
innovatively engineered ball-locking system containing a number of ball
bearings that positions the bezel accurately for improved visibility.
The oscillating mass which moves and turns freely about its axis in an automatic watch. The rotor winds up the mainspring as it swings. A clutch prevents the rotor from over-winding the mainspring.
“Retrograde” is featured on the Bremont Victory and sweeps a segment
of a circle before springing back to the initial position to begin the
Abraham-Louis Breguet used this type of retrograde mechanism in the
late eighteenth century for functions such as the date or an equation of
time. The Bremont Victory includes this complication and provides an
aesthetically pleasing feature to any watch enthusiast.
Sapphire crystal is the favoured material for watch crystal due to
its exceptional hardness (9 on the Mohs scale). Using sapphire crystal
is far more expensive to manufacture than mineral or acrylic crystals,
however sapphire crystal glass provides excellent scratch resistant
A system used to protect the very fragile pivots of the balance staff
against breakage. The jewels for the pivots of the balance staff are
elastically fitted to the main plate. In response to a severe shock,
they give first. A watch with shock absorption properties should be able
to meet the demands of DIN 8308-A. The testing includes the watch being
hit by a hammer at 4.4m/s (equivalent of the watch being dropped from a
one metre height onto a solid wooden floor). The watch must then not
show a rate of deviation of more than +/- 60 seconds a day.
An alloy of steel, nickel and chrome provides longevity and is extremely hard-wearing along with being favourable to the wearer.
A luminous paint used on the dials of watch dial and does not display
any radioactive properties. The luminous effect is based on the
principle of phosphorescence. Super‑LumiNova® therefore needs to be
charged by an external light source. As many as 15 to 20 coats of
Super‑LumiNova® paint are applied to quality dials in very small
measures to ensure that luminous dials are effective whilst not
encroaching on the aesthetic qualities of a superior dial.
Trip-Tick® technology consists of 3 parts: the top bezel containing
the sapphire crystal, the central body consisting of a middle barrel,
and the steel or crystal back. For both longevity and aesthetics, the
separate middle section allows our case designers to use differing
constituents to alter the weight of the watch, and utilise contrasting
colours offering variety between product styles.
is a metal component thats constituents provide low density and high
strength. Titanium is light and comfortable for the Bremont wearer and has increased hypo allergenic qualities.
UTC stands for ‘Universal Time Coordinated’
and allows the wearer to display local time together with the official
world time standard – UTC, or Greenwich Mean Time (GMT), or Zulu time (Z). UTC (replacing GMT
in 1972) is therefore used as the standard clock of choice for
international reference time in communications, military, aviation,
maritime and other activities that cross time zones.
A common scale used to determine the hardness of a material (using a
pyramidal diamond indenter). The impression created by the diamond on
the surface is measured and the hardness calculated. Stainless steel,
for example, ranges from 200 to 240 HV, titanium 210 HV, sapphire
crystal 2000 HV and diamond 4500 to 10,000
A pressure resistance of at least 10 Bar is guaranteed for every
Bremont watch. This corresponds to the pressure of water at a depth of
100 metres statically tested. Water resistant properties cannot be
permanently guaranteed and we therefore recommend that seals are checked
