Girard-Perregaux Watches

It not only increased the accuracy by 4x and created the market standard for frequency, it also allowed the battery to last long enough to be acceptable by the market. Most importantly, it paved the way for quartz technology to become reliable and robust enough to have the market impact that it did. Most who have serviced a Hamilton Electric, Accutron, or Beta 21, know that these movements are just too fragile for the mass production and cost effectiveness that later quartz would achieve.

It is also awesome to see a Motorola logo on a watch movement that existed almost 45 years before smart watches.

Additionally, unlike most modern quartz movements you can actually see gears moving in this one as soon as you get the caseback off. Unfortunately, this technology also nearly toppled the entire Swiss watch industry. The beauties of this watch, inside and out, make it a tragic hero of horological technology. Initially when I received this watch it worked fantastically, soon after however the quartz timing package failed.

Figuring this is such an iconic piece of the Girard-Perregaux brand, I contacted them to see if there was anything they can do about it. I knew that both Patek Philippe and Rolex will service their Beta 21s so I assumed they would be willing to accept it. Fortunately Girard-Perregaux made a huge amount of 35x calibers, so I was able to obtain a circuit board and quartz package from a later year that got this piece back up and running beautifully.

Dating these models is straightforward, but for this watch is a bit of a mystery. If you look closely at the Motorola circuit you will notice four numbers at the bottom. It is believed that the first two numbers denote the year of manufacture and the second two denote the week of that year.

What came out of this restoration is a mint gem of horological history that represents one of the most important and forgotten steps in timekeeping technology.

The carat gold case highlights this model's opulence. The problem with Girard-Perregaux is, when people have enough money to enter this stratus of watches, they tend to go for Lange or Patek or Audemars-Piguet, and it has given Girard-Perregaux a bit of an inferiority complex. I know in the past I have lauded the engineering and manufacture of new complications of almost any kind, but this one feels like desperation.

It reminds me of an aging woman who is not getting the attention she deserves and shows up with smeared makeup and a low-cut dress, and proceeds to embarrass herself at a cocktail party. I have not read anything from you on Ball watches. Can you give the lowdown on those? Are there any acceptable designs there or are they junk made by philistines? Perhaps to distract from the company name, which causes snickers and juvenile jokes from all quarters, Ball Watch has chosen a rather confusing conflagration of branding and marketing. Neither the railroad nor skiers and divers are using mechanical wristwatches anymore.

While some of the designs of Ball watches are forgivable and even attractive, they all use stock or slightly modified ETA movements.
