Master Grand Reveil

AN ALARM WITH TACTFUL DISCRETION

To describe Jaeger-LeCoultre’s Grand Reveil as new would be more than misleading. It would simply be a falsehood because the first version of this monumental wristwatch with perpetual calendar and alarm mechanism date from 1989. Its self-winding Caliber 919 consisted of 350 individual components. That model’s successor, which is now also available with a steel case for the first time, debuted in 2005. Like its forebear, the new model’s dial displays the hours (including a 24-hour indication), the minutes and the seconds, plus calendar information (including all four digits of the year) and the phases of the moon. If the watch is kept in motion continuously, its calendar displays won’t need manual adjustment until February 28, 2100. The alarm function is genuinely new. The self-winding Caliber 909/1 can resonantly summon you from dreamland or audibly remind you of an appointment, and it does both these jobs in an uncommonly discreet and tactfully quiet manner. All you do is press the little button that switches the alarm function from “ring” to “vibration”. Doing so will cause a rubber component to muffle the remarkably loud volume that would otherwise ring from the case of the Grand Reveil. The muffler transforms those merry chimes into a quiet buzz and a palpable vibration. The current status of the alarm mechanism is indicated by a little arrow in a circular window between the “10” and the “11”. The movement, which is based on Caliber 909, measures 8.3 mm in height and contains 363 components. The balancer’s pace is 28,800 vph. The rotor has an outer segment crafted from 22 karat gold. When fully wound, the mainspring contains enough stored energy to keep the watch running for approximately 45 hours.

Rolex : The GMT Master II

Watch Brand : Rolex The New GMT Master II
SCRATCH RESISTANT AND SMOOTHLY RUNNING:
THE INNOVATIVE ROTATING BEZEL
The legendary GMT Master has undergone many metamorphoses in the course of its roughly 50-year history. Rolex has continuously yet conservatively fine-tuned its product so that the first version, which debuted in 1955, its as readily identifiable as a genuine GMT Master as the second version, which was released in 1960, and the GMT Master II, which was launched in 1982. Unlike the original GMT Master, the second hour hand on GMT Master II could be reset forward or backward in hourly increments by twisting the half-extracted crown.This practical feature has remained unchanged to the present day. Of course, time doesn't stand still, not at Rolex or anywhere else. A new GMT Master II, thoroughly reworked inside and out, debuted in 2005. Its case has an improved crown and an innovative bezel that would seem to have a very bright future. Borne on large ball bearings, this bezel runs extremely smoothly. Its golden 24-hour scale contrasts nicely with the black ceramic background, and both turn a could shoulder to scratches. From now on, Rolex will deliver the massive "oyster" bracelet with a new safety closure and a practical extension piece. The self-winding superlative chronometer Caliber 3186 includes an improved mechanism to facilitate the task of switching between various time zones.

Patek Philippe : Gondolo Calendario

Patek's annual calendar has enjoyed many years of popularity since its introduction, so it was no surprise that Patek Philippe decided to use it as a showcase project for renewal of the well-known 315 caliber, with an additional case redesign and dial layout to boot. The reference 5135 Gondolo Calendario sports a tonneau-shaped case with a unique placement of the day of the week and the date and month in an arc between 10 and 2 o'clock, with more uncluttered and temperate dial layout than its predecessor, the 5035. The revised movement 324, with a frequency of 28,800 bph, is a big step for Patek as well with alterations to the famous Gyromax balance and new tooth geometry for the wheels, among other improvements. All in all, for Patek, this is a big step forward and new visual design as well.
