Monochrome Essentials: Introducing the Girard-Perregaux Traveller WW.TC Titanium DLC

Here at Monochrome Watches, we love world time Swiss replica watches uk. It’s probably the most useful complication in this modern day and age for savvy travellers, whether for business or leisure. Girard-Perregaux introduced the WW.TC – the initials stand for World Wide Time Control – in 2000, and last year the model got a major update, both aesthetically and functionally. It was re-branded as the Girard-Perregaux Traveller WW.TC, and recently, Girard-Perreagaux introduced a new version in black DLC-coated titanium.

The new version is lighter, because of the titanium case, and has a cool, all-black look because of the DLC coating. DLC (Diamond-Like Carbon) coating is itself very durable and scratch-resistant, so it adds these properties to the fashion Swiss replica uk watch, making it even more suitable for traveling the globe. Speaking of which, the center of the dial features a three-dimensional representation of the latitudes and longitudes covering the globe. This center part of the dial is also the stage for the chronograph displays, in a tri-compax layout (meaning subdials at 3, 6, and 9 o’clock); the date, which is placed between 1 and 2 o’clock; and the brand’s name and logo.

Surrounding all that is the world timer, with its recognizable city ring, which represents 24 cities from 24 different time zones, and the black/white 24-hour ring that indicates the correct time in each of the cities. It’s practical and easy to read, and because of the black-and-white 24-hour ring, you can also tell whether it’s day or night in the various cities.

The city ring is static; however, the black/white ring is in constant motion and completes a full revolution in 24 hours. Everything can be easily set with the single crown at 3 o’clock. We reviewed the Traveller WW.TC for you 2015 lastest replica watches online store year and addressed everything you want to know about world timers.

Breguet Classique Chronométrie Ref. 7727

Last year, the Breguet Classique Chronométrie, a Swiss Replica Watches that came to market more than a year after its unveiling, picked up the Aiguille d’Or grand prize in this year’s Grand Prix d’Horlogerie de Genève (for a complete list of this year’s winners, click here). Scroll down to read our report on the watch from when we first saw it in 2012.

Improving mechanical-timekeeping precision is one of Breguet’s chief objectives, says brand CEO Marc Hayek. The Classique Chronométrie Reference 7727 incorporates three features designed to accomplish that. The first is a 10 Hz, or 72,000 vph, oscillator. Breguet introduced its first 10 Hz movement in 2010 in the Type XXII chronograph. The new 7727 is the first non-chronograph with a 10 Hz movement. Generally speaking, the higher the beat frequency of an escapement, the less it is influenced by external mechanical disturbances, such as shocks and the wearer’s movements.  Most high-frequency watches suffer shortened power reserve, as the fast beat escapement allows the mainspring to unwind more quickly. The 7727 employs twin barrels to deliver a very respectable 60 hours of autonomy.

The second feature is a lightweight, nonmagnetic balance spring, pallet lever and escape wheel, all in silicon. The balance spring was developed specifically for this Latest Replica Omega Watches, and Breguet claims that it delivers “unequalled isochronism.”

The third, and most intriguing, precision-enhancing feature is the 7727’s use of two endstones incorporating powerful micro-magnets, one for each end of the balance shaft. This arrangement effectively reduces friction at the balance pivots to zero. This translates into some amazing rate results, according to Breguet.  In tests, the balance wheel’s amplitude changes by only about 3 degrees between the horizontal and vertical positions, compared with the 40-plus-degree change seen in most movements, Breguet says.  In an interview at Baselworld, Hayek said he hopes the reference 7727 will achieve timekeeping accuracy of -1 to +1 seconds in six positions, though -1 to +2 seconds would be acceptable.

Magnets are usually a no-no inside (or even close to) a mechanical timepiece, but the silicon escapement components eliminate the usual ill effects.

Breguet also says that we should not be worried about the balance pivots “floating free” rather than being firmly held in place by pierced or concave jewels, as in traditional constructions. The company explains, “As one of the magnets is stronger than the other, one end of the balance shaft is kept in permanent contact with its ruby endstone. Magnetic induction generates a magnetic flux through the balance shaft, developing a force that acts with the gyroscopic inertia affecting the balance shaft. If a blow shifts the pivot out of position, the magnetic attraction pulling it back increases with the extent of the pivot’s lateral displacement. The shaft thus returns automatically to its position, restoring the maximum magnetic flux.”Breguet Classique Ref. 7727

Hayek also noted that the magnetic pivots and silicon escapement components will likely find their way into other Breguet models in coming years.

Aesthetically, the reference 7727 is pure Breguet. The hours and minutes are off center, and the primary small seconds hand appears at 12 o’clock. At 1 o’clock, a patented small silicon hand indicates the 1/10s of a second. Ultra-light silicon reduces the rotating hand’s inertia and so its effect on the oscillations of the balance. The pare-chute shock absorber is visible at 2 o’clock as a reminder of Abraham-Louis Breguet’s 1790 invention. Finally, there is a power-reserve indicator at 5 o’ clock. Hayek said that the red “10Hz” lettering shown in the publicity image will not make it into the final production 2015 Cheap  Replica Watches.

The dial is decorated with six engine-turned patterns. The center has Geneva waves, a clou de Paris design adorns the small seconds dial, the 1/10s-of-a-second counter displays a sunburst pattern, and the power-reserve indicator is decorated in chevrons. The chapter ring for the hours has an edging decoration and the outside rim is in a barleycorn pattern.

Though Breguet introduced the reference 7727 this year, deliveries to retailers will not begin until 2013, so production and pricing details have not been finalized.  Hayek said he hopes to produce models in platinum and rose gold.
