Louis Moinet: Rewriting Chronograph History
The Swiss watch brand Louis Moinet has unveiled an artifact that may change how we look at the history of timekeeping ¡ª a timekeeping device from the early 19th century, invented by the brand’s namesake, that may be the first chronograph ever created.Known as a compteur de tierces ¡ª the term ¡°chronograph¡± had not yet been invented ¡ª the device was built by French watchmaker Louis Moinet between 1815 and 1816. The counter¡¯s balance beats at 216,000 vibrations per hour (30 Hz), allowing its center-mounted hand to accurately measure intervals to 1/60 of a second. (The term tierce, literally ¡°third,¡± was used at the time to refer to 1/60 of a second.)In a press conference held in Geneva on March 21, Jean-Marie Schaller, the CEO of Louis Moinet, appeared with a number of watch experts to introduce the world to the Louis Moinet Chronograph. The 15-year-old brand purchased the counter at auction from Christie¡¯s in May of 2012 for $67,443. The instrument appears to have been very well ma

Help deciding on which Milgauss
I'm looking to purchase my first Rolex and am drawn to the Milgauss for a variety of reasons even though it is not usually the most popular choice especially as a first Rolex watch. I was fortunate enough that my local AD had both the blue and black dial in stock, so I was able to compare the two. I'm still debating between blue or black dial, but am slightly leaning towards the black dial GV. This is where my question comes in. What are your thoughts on the original style black dial GV with the dual color lume vs. the new style black dial GV with the single color lume. Also, does anyone happen to have seen both and have an opinion on brightness and longevity of each?Finally, I realize that the dual-color lume would require buying second hand as it is no longer made. I'm guessing that since it is pushing 10 years old, it would be due for a servicing immediately upon buying unless I was fortunate enough to find one that just got serviced? Any difference in buying M/V/G/Random serial?
