The Luxury Watch Blog

When Luxury Watches are manufactured there are many things associated with cost.

1. Research and Development

All watches have complex movements some that are on the cutting edge of technology.

There are different types of movement and all are very complex. These movement have precious stones (Ruby’s etc..) in them

some are made of precious medals. The manufacturing process is very complex because they need to be very small and very complex and therefore require special machinery. There are a few unique watches that stand out with the complexity of their movements and therefore are very expensive. However all watches hold complex movements.

Valjoux 7750 chronograph, I got a rather prestigious watch with a top shelf Ebel 137 movement. Based on the rare Lemania 1351, it is used in only a few other brands; Brequet being the only one I can think of.

Functionally, this is the perfect chronograph. Collecting many, I never thought I’d actually see one. Everything functions perfectly. No rotational eccentricity of the minute hand, i.e. the position of the constant seconds hand is coordinated with the movement of the main minute hand, for ALL 60 minute chapters. Same is true of all the chronograph hands, including perfect coordination positioning of the elapsed minute/hour hands; very rare. Also, on reset, all go to straight up 12. This is not your typical mechanical chronograph. A certified chronometer, its at -1.4 s/d when worn 23+ hours per day over a 30 consecutive day period.

Luxury Swiss watch company Jaeger-LeCoultre—in partnership with actor and activist Leonardo DiCaprio—has created its “Time to Care” program, to benefit the Leonardo DiCaprio Fund at the California Community Foundation.

The fund-raising focal point of the initiative will be the sale of two timepieces in the fall of 2008. Both will be the first of a limited series of watches that feature technology never used before, Jaeger-LeCoultre said in a statement. All proceeds will go to the Leonardo DiCaprio Fund at the CCF in order to further its work with environmental programs worldwide. The watches will be presented exclusively at the new Jaeger-LeCoultre Boutiques in Boca Raton and Beverly Hills, scheduled to open summer and fall of this year, respectively.

Initial Impressions

When the watch first arrived from Debaufre in their usual priority mail box. The watch was very well packaged and shipped. They include the customary Debaufre Red/Black presentation box, warranty card and paperwork. The presentation box is very nice and one to hang on to.

When I took it out, the first thing I said was “WOW, This thing is BIG!”. The reason they call it the Magnum 44 is that its 44mm across the case, not including the crown.

Alicia Keys & Jaeger-LeCoultre - The Reverso Squadra Lady

“Superwoman”, the new song from nine-time Grammy Award winner Alicia Keys creates a perfect occasion to bring the latest creation of Jaeger-LeCoultre, the Reverso Squadra Lady to stage.

This song is dedicated to women, and the Reverso Squadra Lady perfectly reflects this multi-faceted feminine universe with two faces in one watch, a fast and clever strap-change system, a stunning array of materials, a classic design and the sparkle of diamonds. Equipped with the latest generation of Jaeger-LeCoultre movements, these models combine the signature Reverso Squadra features with a degree of refinement reserved exclusively for feminine wrists.

In horology, the term complication refers to any feature beyond the simple display of hours, minutes, and seconds in a timepiece.

A timepiece indicating only hours, minutes, and seconds is otherwise known as a simple movement. Common additions such as day/date displays, chronographs and automatic winding mechanisms are usually not sufficient to permit a movement to be called complicated. Moreover, that a watch movement may be a Certified Chronometer does not itself count as a complication.

A rotating pendulum inside the case is attached to a relatively large gear which meshes with a very small pinion. As the wearer moves, the pendulum turns and spins the pinion at a very high speed - up to 100,000 rpm. This is coupled to a miniature electrical generator which charges a storage device which is a capacitor(s) or a rechargeable battery. A typical full charge will last between two weeks and six months.

Applications

How it works

To accomplish this, the watch contains a semicircular ‘rotor’, an eccentric weight that turns on a pivot, within the watch case. The normal movements of the user’s arm and wrist cause the rotor to pivot back-and-forth on its staff, which is attached to a ratcheted winding mechanism. The motion of the wearer’s arm is thereby translated into the circular motion of the rotor that through a series of reverser and reducing gears, eventually winds the mainspring. Modern self-winding mechanisms have two ratchets and wind the mainspring during both clockwise and counterclockwise rotor motions.

The fully-wound mainspring in a typical watch can store enough energy reserve for roughly two days, allowing automatics to keep running through the night while off the wrist. Usually automatic watches can also be wound manually by turning the crown, so the watch can be kept running when not worn, and in case the wearer’s wrist motions are not sufficient to keep it wound automatically.[1]

Preventing overwinding

A problem that had to be solved with self-winding mechanisms is that they continued working even after the mainspring was fully wound up, putting excessive tension on the mainspring. This caused a problem called ‘knocking’ or ‘banking’. The excessive drive force applied to the watch movement gear train made the balance wheel rotate with too much amplitude, that is too far in each direction, causing the impulse pin to hit the back of the pallet fork horns. This made the watch run fast, and could break the impulse pin. To prevent this, a slipping clutch device is used on the mainspring so it cannot be overwound.

The slipping spring or ‘bridle’

The ’slipping mainspring’ device was patented by Adrien Philippe, founder of Patek Philippe on June 16, 1863, long before self-winding watches. It was originally invented to allow simultaneous winding of two mainspring barrels. In an ordinary watch mainspring barrel, the outer end of the spiral mainspring is attached to the inside of the barrel. In the slipping barrel, the mainspring is attached to a circular steel expansion spring, often called the ‘bridle’, which presses against the inside wall of the barrel, which has serrations or notches to hold it.

As long as the mainspring is less than fully wound, the bridle holds the mainspring by friction to the barrel wall, allowing the mainspring to be wound. When the mainspring reaches full wind, it’s force is stronger than the bridle spring, and further winding pulls the bridle loose from the notches and it simply slides along the wall, preventing the mainspring from being wound further. The bridle must grip the barrel wall with just the right force to allow the mainspring to wind fully but not overwind. If it grips too loosely, the mainspring will begin to slip before it is fully wound, a defect known as ‘mainspring creep’ which results in a shortened reserve power time.
