What if you are a pilot and you want the ideal Pilot Watch (Flieger). Probably your answer is that the watch needs to be large and extreme good readable. Lange and Sohne manufactered in 1941 their classic B Uhr Type-B for the German Luchtwaffe. While we call this type of watch a "Fliegeruhr" ("Pilot's watch"), or short "Flieger", it was actually meant for the Beobachter (navigator), hence the name B Uhr, which was short for Beobachtunguhr. These watches were extreme accurate and quite expensive. Therefore the watches were owned by the Luchtwaffe, not by the beobachters. This watch had a thick 55 mm wide case, big hands and bright thick hour markers, which proved to be a classic and loved design. A big leather strap allowed the watch to be strapped on the Beobachter's sleeve (see the first photo above). The Lange and Sonhe B Urh Type-B became the mother of all Fliegers.GW-3000B model. While that model was a quite impressive at that time, Casio didn't sleep. In 2012 Casio presented a new model Sky Cockpit at Baselworld. Casio worked closely with the Royal Air Force to design this models, so this watch has functions that pilots really want in a cockpit. Instant Zulu Time, and a Thermometer function were such special requests. The result was quite surprising and very nice, the GW-A1000 "Gravity Defier". While the GW-3000B was already quite big at it's time, the GW-A1000 looks even bigger. The official dimensions by Casio (for the resin versions) are 52.5 x 49.8 x 15.5mm for the GW-3000 and 54.1 x 52.4 x 16.4mm for the GW-A1000. Also the weight has increased a bit from 74g to 85g. Of course this model is quite heavier because of the bracelet. The weight depends on how many links are removed to match your wrist.
Note: The name "Gravity Defier" was in Europe already in use since Casio Released the GW-2000. Therefore the name Gravity Defier applies currently to the GW-2000, GW-2500, GW-3000, G-1100, G-3000, GW-A1000 and GW-A1100. The name Sky Cockpit was introduced in 2010 with the GW-3000 model. Thanks Jean-Manuel for bringing this to my attention.
The GW-A1000 compared to the GW-3000B
Note: The basic GW-A1000 with resin straps weighs only 85 gram. With three links taken out my Gravity Defier weighs 144 grams.Next mode is the Stopwatch Mode. It is possible to measure times up to 2 hours. The minute hand shows the seconds, while the hour hand shows the minutes. Wait, I hear you think, 2 hours is 120 minutes. Indeed, the upper dial is a 24 hour dial. It takes 120 minutes for the hand in the upper dial to go totally round. There are two ways to use this Stopwatch mode. First like a usual stopwatch. The upper right button is used to stop, start and if desired continue the stopwatch, while the lower right button resets the Stopwatch. The second way is using the so called Fly Back function. After you start with the upper right button, you can start a new stopwatch operation instantly by pressing the lower right button. You can do this over and over again and stop the Stopwatch eventually by pressing the upper right button. Of course the hands need time to point the right time, but they move to the correct positions. The second hand moves in 1/20s positions until 30 seconds. Then it stops at the 12 position. When the Stopwatch is stopped the second hands shows the correct 20th of a second again.
Tiktox in the UK, know for their extensive selection of G-Shock replacement parts. The overall good quality finish of this watch, the tough design and technology does justify such a price, though it will probably not be affordable for everyone. In my opinion, this Gravity Defier is one of the best looking models in the more premium G-Shock range.
