![]() ![]() The Seiko SNZFG15 sure can! What you have here is your basic, cheap, Seiko automatic watch with a push/pull crown and non-hacking movement. I could have added so many Seiko watches to this list, but not all the Seiko watches I own can stand up to camping and DIY chores. The SNZF has been discontinued, but you can still easily find brand new ones on Amazon and eBay. If you are trying to decide between a rugged quartz watch or a rugged automatic watch, this is the main factor to consider: do you experience hard, repetitive shocks or constant vibrations on a daily basis? If the answer is yes, then go quartz, if not then check out the watches I have here. My warning about automatic watches doesn’t mean they can’t handle some abuse they are perfect for the daily grind. I change the oil on my van, build stuff, climb in and out of the attic, knock them around, go hiking and fishing, play sports, etc, you name it. I wear an automatic watch almost every day of the week. I’ve added a few watches from the original thirteen I picked as my collection has grown or I have had the opportunity to review more watches. I have had first-hand, real-world experience with every watch on this list or extended time with the brand and its other similar watches. If you need and want a rugged, reliable, do-it automatic watch, then this list is for you. Many instances of watches running slowly or fast would not have happened in the first place, if the watch was anti-magnetic.I have recently updated my picks for the most durable automatic watches. In response to the effects of our increasingly digital environment and its magnetism watch manufacturers have started to use silicon balance springs over the past few years. Just think of all the smartphones, purses and briefcases with magnetic closures and digital devices everywhere. Why, you ask? Because we are surrounded by magnetic fields. The watch manufacturing community has collected data, which shows that 80% of watches that require service are magnetized (to greater or lesser extent). Let me get back to the subject of magnetism very quickly before I conclude. Please don’t do the same as one of my customers: He attempted to regulate his IWC Da Vinci himself, and in doing so, he caused significant damage of 5,000 Euros. Depending on the watch and your location the cost runs somewhere between EUR 20 and 50. Most cases are resolved very simply by fine-tuning the watch on the timegrapher. An impact caused the dial to move and create binding on the digits (this is becoming more frequent lately)Īnytime when your watch is running fast or slow, it is advisable to see a watchmaker and let them diagnose the cause for the inaccuracy.The movement needs to be professionally serviced.An impact on the watch altered the spring’s key.The watch has sustained some significant impact and caused the last winding in the spring to skip forward.The balance spring has been magnetized (this may cause the watch to go fast by as much as several hours per day).The movement requires professional service.Of course, there are reasons to cause a watch to be unduly fast or slow.Ī few of the reasons why a watch may be fast: Well, simply put: This is absolutely impossible! It is a scientifically proven fact that isochronism (consistent oscillation) cannot remain constant in a wearable watch. That’s when my customers usually disagree: “But my neighbor tells me that his Rolex has been 100% accurate for five years with no time deviations ever”. The general rule for mechanical watches is that a deviation of 10 seconds or less per day is good. Over two months this variation accumulates, and that watch will be 8 minutes fast (8 s/d x 60 d = 480 s = 8 minutes). ![]() For example, the timegrapher detects a deviation of +8 seconds per day (this is considered good accuracy for a mechanical watch). First of all, a claim about a 10-minute delay or advance on the watch has to be put into perspective and interpreted correctly by the watchmaker. Is your watch gaining or losing time every day? Very often when a customer comes to us, the reason is an inaccurate running of their watch. ![]()
