What Is The Difference Between A Chronograph And A Chronometer?
The most common self-winding chronograph movement is the Valjoux 7750 caliber, introduced in 1973, produced by the Swatch Group factory forge Eta since the manufacturer Valjoux was taken over. The campaign is known for its reliability and certified as a chronometer.
Long-Running Chronograph Movements
But what is the difference between a chronograph and a chronometer? A chronograph is a watch with an additional stop function or itself. A chronometer is a watch whose precise accuracy has been tested and certified by an independent institute.
The high art in chronograph construction is the development of your caliber. This is almost a must for luxury brands. They usually supplement the already complicated function with further technical refinements, such as a calendar function.
How Does That Work With The Slide Rule Function?
It is also equipped with a slide rule function that enables three-set tasks to be quickly solved. For example, you can determine a speed based on the distance traveled and the time required (stopped with the clock) or convert currencies if you know the exchange rate: For example, if one money is worth 1.7 times another, you can use the outer Turn the ring 17 to the inner 10 and get all prices converted around the dial. Multiplications and divisions are also possible. With the help of the slide rule bezel, the wearer can set the size on the outer number ring to, for example, a fixed mile marker on the left edge of the dial.
Different Pusher Shapes For Chronographs
As different as clocks are, the control elements of the stopper can also be other. There are handles with integrated protection, screwed handles, shaped handles, and mushroom handles. The following picture gallery shows what the different pushers of the chronograph look like:
- Pushers with integrated protection: the Royal Oak Chronograph from Audemars Piguet
- Shaped pushers: Mühle-Glashütte Lunova Chronograph
- Mushroom pushers: Alpina Startimer Pilot Automatic Chronograph
- Screw-down pushers: Vacheron Constantin Overseas Chronograph
Since the timepiece like Rolex watches (นาฬิกา Rolex which is the term in Thai) is one of the most popular functions among watch fans, watch manufacturers present new clocks every year. Often there are entirely new models; some are equipped with new movements or stand out from the other timepieces due to their extraordinary properties. The current trend is for chronographs with panda dials, in which the totalizers in black contrast with the light-colored dials.
