how to demagnetize a seiko watch

in different positions, like dial up vs dial down). So after asking locally for someone to demagnetize and being disappointed in the responses (change the battery one person said to me), I decided to buy one of those demagnetizers off eBay. A mechanical watch could be magnetized if placed near an electronic product, say your iPhone, for a significant amount of time, or simply when it is exposed to magnetic influence. A wave with a 60-second period, for example, suggests a flaw in the fourth wheel, which rotates once every 60 seconds. Ruh-roh. 4 posts • Page 1 of 1. supa4 Member Posts: 268 Joined: Tue Sep 06, 2011 12:38 am. Step 1: Remove Strap Compress the flanges on your stock strap and gently pull it out. The symptoms of magnetism are so diverse that it is wise to routinely demagnetize your watches before adjusting them. Following your watch accuracy result obtained using the Toolwatch app, three cases can be listed if your accuracy is not between the -10/+10spd (sec per day) range. The built-in microphone will pick up the tick-tocks of the watch and output a stream of reading. Hello dear watchmakers. Buy a cheap demagnetizer from Amazon or eBay. Do not be alarmed if the rate changes while you’re manipulating the stud carrier; it is natural for rate to change as you are essentially changing the distance between the regulator and stud carrier, and therefore the effective length of the hairspring. You may have to register before you can post: click the register link above to proceed. All Right [email protected] | 1402, 35-45 Chai Wan Kok St, NT, Hong Kong, Sapphire crystal, Latest, Case, published, demagnetizing a watch is a relatively simple process, Why Waterproof / Water Resistance Rating Isn’t What It Seems, How to Regulate a Watch using a Timegrapher, How to Upgrade DWC Diver to a Case with Sapphire Crystal. This does not affect the accuracy of the watch unless in extreme cases, but in the long run, beat error can cause uneven wear. Most watches, even dress watches, are rated for water resistance to at least 3 atmospheres, which is equivalent to roughly 30 meters. Procure a piece of heavy linen thread about 3 ft. long, attach one end of it to the ring of the watch, hold the other end and turn the watch around until the thread is twisted at least one hundred times. One lever is attached to the end of the hairspring. “Hygiene” in this particular context means “the absence of foreign elements inside the watch”. Always best to read the tech repair pdf before embarking on anything potentially damaging, but it's your watch. You want to insert the knife into the gap between the bezel and the case. Furthermore, the case back of a Seiko watch reveals a bunch of different information. Inexplicably, my anti-magnetic tweezers occasionally get magnetized. If the coils stay stuck, the effective length of the hairspring will be much shorter than normal, causing the watch to run abnormally quickly. For your reference, a Sellita SW200 has a factory rated maximum amplitude of 315 degrees and minimum amplitude of 210 degrees, and general consensus for the maximum amplitude of a Japanese movement (like Miyota and Seiko) is in the range of 270-315 degrees, while an amplitude above 230 is considered acceptable. (don't do that!) The light should come on … To do this, you’ll need a watch case knife (if you don’t have one, you can find one in our online store). Although regulation is a job usually delegated to watchmakers, with sufficient knowledge and proper equipment, you can regulate your watch at home as well. Let go of the ON button when the watch is arm’s length from the unit. As a reminder, usually we consider accuracy within that range to be acceptable but this can be challenged depending on the certification of your watches. Move it toward + to gain time, - to lose time. Most de-gaussing equipment for this purpose is an "open" primary coil with the I`s missing. If you’re demagnetizing a small part, a strong demagnetizer might shoot it across the room, so it’s wise to hold or cover it. The second kind is a classic degausser. Seiko watches which have the same movement (7s or 4r equivalent), dial size (28.5mm), and crown position (3’o clock) as ours can have their movement assemblies (i.e. There will be two lines on screen. These have been around forever, so you have a choice between many different kinds. If the lines are slanting upward, that means the watch is fast, and if downward, slow. This is usually automatically detected by default setting, but if the detection is wrong, it can be manually set. Regulating the accuracy of a mechanical watch. The Seiko had been amazingly accurate then started running about 30 sec,/day fast. I’m not sure what part was magnetized, but a zap with the demagnetizer (literally) straightened out the timing traces. All rights reserved. Fortunately, demagnetizing a watch is incredibly quick and easy. A mechanical movement functions quite literally by the movement of its mechanical parts. If this is your first visit, be sure to check out the FAQ by clicking the link above. How to protect a watch from magnetism. A healthy movement should, at full wound, have a high amplitude, in the range of 280-320. Note that the important distinction is consistency, and that distances “regulation” from “adjustment”, which refers to the work done to a watch when it runs with different rate under different conditions (e.g. To start viewing messages, select the forum that you want to visit from the selection below. Well yes, If you think of a quartz watch it generates movement through a small magnet which is given its torque to turn by the magnetic field generated around it, a considerably weak one normally. Beat rate is by default set to “auto”, and should be left as is. Place your watch on the the demagnetizer for few seconds. Same rules: steady hand, and move in tiny bits. Move the regulator to change the rate.

Normally they should be of equal length, but if the balance wheel swings more in one direction and less in the other, one tick will be longer than one tock. Seiko 6139 Pogue. 21,600bph, or beat per hour, would translate to 6 ticks per second). Note that the smooth line, rate of +4s/d, and pretty good amplitude indicate a healthy movement. You can use our dive watch parts to mod Seiko dive watches (SKX007/SRPD). Place your watch on the the demagnetizer for few seconds. Then you can move on to the rate. So the moving of the minute hand need to be on-point when the second hand passes the 12 o’clock. Like all watchmaking tools, demagnetizers run the range from cheap stuff from China to solid equipment to poor value-for-money equipment with a Swiss name stamped on it. The distance between the lines represents beat error. But these waves have a fast period, much faster than the escape wheel rotates, so it isn’t that. The watch started running fast immediately. Next check the beat error. This can be found online easily (for example, Seiko NH35 has a lift angle of 53, while that of Miyota 8 is 49). However, like any sensitive precision instrument, a watch needs periodic servicing to ensure that it functions perfectly. Otherwise, you could chase the rates in circles. At full wound, it should be in the range of 280-320. All text and original images (c) 2016-present. Many resources online say that quartz watches should not be demagnetized but I know that grand Seiko offers a demagnetizing service for their watches. Learn More: Here. These parts will cause erratic timing, and some of them—like steel hairsprings—will have calamitous effects. I timed it over several days and it was about one minute fast per day. The watch came with a waterproof and dustproof oxidized case which in conjunction with a heat-insulated disk provided protection to the movement. Observe the lines: the top line shows signs of an unhealthy movement — instable line and low amplitude. A timegrapher is a device that tells you more than just the accuracy of a watch. General consensus is that it is a good pratice to check your watch on a timegrapher periodically, so as to monitor the health of the movement. The degree is lift angle. And if yours has wood-grain decals, it’s extra proud. To use it, hold the watch an inch over the center of the unit, press the ON button, and keep the button depressed as you slowly move the watch away from the unit. Be aware that this tutorial only gives you an introductory perspective into what goes into modifying your time piece. And if the lines are irregular, that points to a greater problem, which is when you should get the watch to a professional watchmaker for a detailed check-up. This tells you how much rotation is in one full swing of the balance wheel, and is an important piece of information in determining the health of the movement. If the message “Magnetism detected” appears on the screen, you’ll need to go to the next step: plug in the Demagnetizer, press the start button and hold it down. Removing the case back will help and then removing the movement from the watch. This figure is used by the timegrapher to calculate the amplitude of the movement. Is there something reasonably priced that the average Joe can buy to demagnetize my Seiko automatic watch at home if it's proving to be very susceptible? Each Seiko watch has a serial number that is unique to that exact watch. Those movements did not have Sec Hand, just an Hour & Minute. Seiko watches which have the same movement (7s or 4r equivalent), dial size (28.5mm), and crown position (3’o clock) as ours can have their movement assemblies (i.e. Since a couple of my other watches were magnetized and it appeared to move the needle doing the ad hoc compass test, I assumed the watch was magnetized and demagnetized it using the ubiquitous blue eBay demagnetizer.Now it's running -9 seconds. Depending on how much of the broken stem is left in the movement, this can be an easy fix or a difficult repair. Seiko Prospex SNJ029 “Arnie” The brand was connected with numerous famous events of the 20th century, including the American war in Vietnam. I mean it's off by about 22 seconds (fast) after 24 hours which isn't great, but is a darn sight better than it used to be. Our case with sapphire crystal makes it easier to replace without specialized tools. You demagnetize a watch with a demagnetizer. share. You set the watch down on on the unit, press the button, and zappo—the deed is done. The first one i purchased broke after only using it twice, i e-mailed seller and they sent me a replacement, product is ok for what i needed which was to demagnetize a vintage Seiko dive watch, which had been on an automatic winder and got magnetized and was keeping very poor time as a result. You don’t have to open it up; you don’t even need to take it or send it to a repair shop that might charge you something to the tune of $30. A good example is SNZF Urchin. A demagnetizer requires an alternating current to remove the magnetic field from the watch; it does this by rapidly changing directions of the current, which changes the orientation of the magnetic field. Thanks. Gallet Commander and the Excelsior Park 42 Caliber. Here is a quick overview of a generic Seiko watch mod. When I bought my staking set, for example, it was a boiling ball of magnetism that could power a small MRI coil. This in turn causes the dipoles to end up in a random order, rendering the watch demagnetized. And closer to zero is better. So what you need to do is to simply pry it off. (e.g. So a functional timegrapher gives you many useful pieces of information that you can use to determine the condition of the movement. Some may consider the 6139 “Pogue” to be a bit of an eccentric selection within our top 10 Vintage Seiko watches list, but I’m ready to defend the choice.

The watch was returned to Hoel at the location where his plane went down at the Maas River. You can use the Seiko serial number in conjunction with the movement number to calculate the year of manufacture. The watch should be moved 2-3 feet away slowly from the the source whilst it is switched on. Surprisingly it's actually kept time pretty well. But the proper way to diagnose and regulate a watch is by using a timegrapher. (Click to zoom in) The two levers: no.1 is the stud carrier (notice it’s at the end of the hairspring), and no.2 is the regulator. But don’t worry. Cause 3 – Serious Problems With The Movement If your watch still stops even though you wind it everyday and no magnetization is known, then there could be a serious issue with your watch’s movement . So, if it says +3s/d, that means the watch gains 3 second per day.

You may have to register before you can post: click the register link above to proceed. The 5-digit number is the beat frequency, meaning how many ticks are there within a second. The watch had a distinct military appearance and offered soldiers the option to engrave their personal information in a large clasp located in the 3/4 inch strap. But anything above 250 degrees can still be considered healthy amplitude. This effectively makes the balance spring shorter, and a shorter balance spring makes the watch run faster than it normally would. Regulation, in the sense used by watchmakers, means the work done to a watch when it runs consistently faster or slower. 2. On the internet you can find multiple ways to regulate a watch; some even say you can do it with just an app. Options. Some of these parts, like the levers we are going to talk about, are especially susceptible to external force as they are movable. Here is a quick video guide to get you started: First off, let’s clarify what “regulation” means. If the hairspring is magnetized, its coils might stick together and slap against each other as they unstick, which would be apparent as erratic timing traces. One or two zaps should suffice. Seiko watches have a 6 or 7 character serial number on their casebacks. Now allow the thread to unwind, and as the watch revolves, pass it back and forth near a powerful electromagnet. After demagnetizing a watch, you would want to minimize any further risks of magnetism. So after asking locally for someone to demagnetize and being disappointed in the responses (change the battery one person said to me), I decided to buy one of those demagnetizers off eBay.
