A healthy movement should, at full wound, have a high amplitude, in the range of 280-320. 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. So, if it says +3s/d, that means the watch gains 3 second per day. Labelled in s/d, it tells you the time error in seconds per day. This is the number most people are looking for. Each number tells you an important piece of information about the condition of the watch tested: When the timegrapher is running, it’ll show 4 numbers on screen. So a functional timegrapher gives you many useful pieces of information that you can use to determine the condition of the movement. Through the built-in microphone, it picks up the ticks and tocks of the watch and calculates indicators of the general health of the movement. But the proper way to diagnose and regulate a watch is by using a timegrapher.Ī timegrapher is a device that tells you more than just the accuracy of a watch. On the internet you can find multiple ways to regulate a watch some even say you can do it with just an app. If they are moved, the accuracy of the movement can be affected, and in most cases, regulation can be of help here. Some of these parts, like the levers we are going to talk about, are especially susceptible to external force as they are movable. Therefore it is imperative to maintain clean working environment, and always wear finger cots.Ī mechanical movement functions quite literally by the movement of its mechanical parts. Any foreign elements caught in the gear train of the movement can slow down or even stop the movement. This could be small debris, tiny strands of fiber, or even hair. “Hygiene” in this particular context means “the absence of foreign elements inside the watch”. Luckily, demagnetizing a watch is a relatively simple process. You can tell a watch has probably been magnetized if it runs exceedingly quick, and in some rarer cases, slow. 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. With the pervasiveness of electronic products nowadays, magnetism is the no.1 cause for inaccuracy. Before regulation: common cause of inaccuracy So proceed with extreme care and caution. One slip up could mean the death of your watch. Note of caution: with regulation, you are accessing and manipulating the inside of the movement. Adjustment is much more complicated than regulation, and should not be attempted by non-professionals. in different positions, like dial up vs dial down). 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. Regulation, in the sense used by watchmakers, means the work done to a watch when it runs consistently faster or slower. First off, let’s clarify what “regulation” means.
