These Derby Swissonic watches are hard to find in working condition and are reportedly hard to keep working. The numbers don't roll, they rapidly advance. In fact, it's a jump hour and jump minute watch. First, this watch is also a jump hour watch. The watch is definitely an eye catcher, especially to the fan of flip clocks, and could be said to be similar to a rolling wheel, rolling drum or cyclometer clock. Now this was more of a flip clock type watch with the drums instead of flat discs to display the time. These watches contain standard mechanical movements but have rotating discs instead of moving hands.ĭuring this time period, around 1974, the Derby Swissonic “JAZ” came to be. The biggest jump hour revival took place in the 1960s and 1970s with these digital display watches being marketed as a cheaper alternative to the new electronic digital watches. The first Jump Hour wristwatches appeared in the Art Deco period in 1920s and into the 1930s but that was just a short revival of this technology. These watches had a short run in the late 1800s then essentially stopped being manufactured. The type of watch invented by Pallweber came to be known as a "jump hour" watch due to the hour advancing rapidly. Pallweber was granted numerous patents between 1882-1887 related to these watch types, and licensed the concept to various watch manufactures (including IWC).Īs an aside - Joseph Pallweber, as you all may know by now, was not only credited with the first digital display watch, but also the first digital readout clock and most importantly the first flip clock. Production of marketable digital display watches began after Josef Pallweber invented a pocketwatch with numeric display. In fact, I've never run into a flip clock fan that didn't appreciate the cyclometers as well. Most flip clock fans don't even roll their eyes when they see a rolling drum clock (aka a cyclometer) referred to as a flip clock on eBay. So we're going to have to look at a cyclometer or drum-type clock as a possible candidate for an official flip clock fan watch. Proper flip clocks rely on gravity to work - the reason flip clocks were not considered as an option during the Apollo Missions. I'll let you decide.īut first I have to make the bold assertion that there will likely never be a flip clock on your wrist. I believe I've discovered a wristwatch that may be suitable for a fan of flip clocks. ElasticBouncingSecondHand = 2 StationClock. ElasticBouncingMinuteHand = 2 // second hand behavoir StationClock.
