The result is a watch that can also function as stopwatch at the same time. But it is NOT a chronometer.Ĭhronographs are made by including an extra feature into a normal watch.
This is a chronograph watch – notice the extra subdials and pushers that are used to operate the stopwatch function (the watch is the Tissot Couturier Automatic Chronograph). Similar terms, but two very different things. Chronograph on the other hand, is a watch with a stopwatch feature. To recap, a Chronometer is a precise watch. People already know that quartz watches are accurate so it seems a bit useless for watchmakers to make a quartz chronometer.ĭifference Between Chronograph And Chronometerīefore we go deeper into chronometer’s origin and certification, I would like to clear the air about the most common misunderstanding around it: is Chronometer the same as Chronograph? There exist quartz chronometer, which is a quartz with very precise accuracy but it’s not really used. One thing that will surely be in everyone’s mind is whether a quartz watch can be called a chronometer or not.īy going the technical specification, all quartz watches will qualify as chronometer as it have a much better accuracy (+-10 seconds per MONTH).īut we have to remember that quartz and automatic watches are different animals altogether and should not be put into competition against each other.ĭue to this, chronometer watches nowadays almost always refer to automatic watches. Thus in short, chronometer is a watch with greater accuracy. Of course this is unacceptable for those involved in fields that require precise timekeeping (more about that later on below).ĭue to this, the Chronometer standard is invented to certify automatic watches that have the utmost accuracy, with maximum -4 or +6 seconds per day. p/s: Rolex holds the record as the manufacturer with the most movements certified as chronometer You just got to ensure the “Chronometer” wording is on its dial to find out.
And if you let it be for a month, the watch can be off for up to 10 minutes or more.ĭespite its price, not all luxury and high-end automatic watches are chronometer. This means over a week, an automatic watch can be off by 2 minutes. Normal automatic watches (at least the more affordable ones) have an accuracy of about +-15 to 25 seconds per day. It is well known that automatic watch is not the best in terms of accuracy. What differentiates a chronometer and a normal watch? And by the way, the term is mostly used for automatic watches only nowadays. This horological jargon is indeed a bit overwhelming at first but as I can attest, it’ll become easier as we read more and more about the world of watches.Ĭhronometer, in the easiest explanation is an accurate watch. Someone is not a real watch fan if he does not know what a chronometer is all about.
