The Girard-Perregaux WW.TC Financial Power Reserve World Timer ref. 49850-11-152-BA6A in stainless steel has a case diameter of 41 mm and a thickness of 11 mm. This watch is fitted with a sapphire display case back and calibre GP033G0 with a power-reserve of 46 hours and 27 jewels.

The dial features a power-reserve indicator, a 24-hour rotating ring with night/day indicators, a red pointer to show the 9am opening time of the stock markets and a rotating disc with 24 global stock market trading cities. The cities' disc is rotated via the crown located at 9 o'clock and the Financial function indicates when these stock markets are open for business. To indicate the opening times, each city has been placed on the disc in a particular order based on their timezone location.

This watch is very useful in telling time across 24 different cities but is not complicated to use as most people would think. Let's now explain how it works.

The first thing that needs to be done before setting the time on the hands, is to rotate the cities' disc —via the crown at 9 o'clock— and align your location with the 12 o'clock marker. Then —via the crown at 3 o'clock— set the hands to the correct time while making sure that the hour displayed on the 24-hour night/day ring underneath your location shows the correct number matching the military time. i.e. The watch in the pictures is set to 10:10am New York City time which means that the city indicator showing New York should be aligned with the 12 and the hour disc underneath it shows 10 instead of 22 as it is 10:10 in the morning and not 10:10 at night. 

The movement in a World Timer complication like this will automatically rotate the 24-hour ring counter-clockwise as time advances in order to make sure that the hands and time shown on the ring are always synchronized. That way, when you want to tell the time for other cities, the numbers on the ring will always show the time in those cities. 

For instance, if it's 10:10am in New York City and we want to know what time it is in Chicago and in Rio de Janeiro, we just need to look at the 24-hour ring and see what number is displayed under these cities. Based on the picture below, we now know that it's 9:10am in Chicago —red pointer indicates 9am— and 12:10 pm in Rio de Janeiro —sun icon indicates it's noon.  

The red pointer on the 24-hour ring will always point at the city that will be opening their stock market next at 9 in the morning.  

The dial is very nicely finished with an anthracite center with applied Arabic numerals  at 12, 3 and 6 and luminous dot markers. It has a very unique sunburst effect and provides different hues from dark blue to a grayish blue depending on the lighting conditions. The running seconds and power-reserve indicators include white hands and a combination of red and white accents that provide a very nice contrast.

The 24-hour ring features a black and white night/day indicator, a golden moon indicating midnight and a golden sun indicating noon.

This watch wears smaller than 41 mm and comes with a black alligator strap with a very comfortable and easy to use deployant buckle.  

Overall, this watch has a lovely wrist presence that is not only reserved to those watchlifestylers in the financial sector, but also very suitable for any watchlifestyler in search of a useful complication that is easy to use. It will most definitely become a conversation piece wherever you travel.

This watch is one of our favorite top three World Timers along with the Patek Philippe ref. 5110 and the new Frédérique Constant World Timer. Now, to us the biggest downside of this timepiece is the lack of a date display.
