Scores of Individual Models
The PR 100, part of the T-Classic series, has a wide range of different versions, a typical Tissot
trait. The company has a history reaching back over 160 years, and their ultra high-tech multifunction watch Touch
is now one of their most iconic models.
Dozens of different PR 100 models come together to create an extensive collection dominated by three-hand watches with date displays perfect for any occasion. On the one hand, the watches are elegant enough to wear as a dress watch, matching stylishly with a suit and tie. On the other hand, they also make for wonderful robust everyday watches, accompanying jeans and a t-shirt. Most models have a diameter of 39 mm, a size which looks good on both larger and smaller wrists. However, if you prefer a larger case, then the 41-mm chronographs are just right. Smaller, 33-mm versions are designed primarily for women.
PR 100: Buying Tips
Looking for something sporty or prestigious? Thanks to the countless different PR 100 models, you can choose what suits you best. A classic introductory model is available for less than 500 euros, featuring a stainless steel case and bracelet as well as a black or dark blue dial. The sporty tone of the PR 100 is emphasized in some stainless steel models with chronograph functions and rhodium gray or silver dials. More stylish, decorative options are PR 100s with yellow or rose gold coating or bicolor models, which combine yellow gold and stainless steel.
Tissot offers a large selection when it comes to movements. Lovers of Swiss watchmaking can choose versions with mechanical calibers, while other versions are powered by the Powermatic 80, an automatic caliber with a remarkably long power reserve of 80 hours. If the movement has been officially certified by the Contrôle Officiel Suisse des Chronomètres (COSC, Official Swiss Chronometer Testing Institute) for precision and accuracy, then "CHRONOMETER OFFICIALLY CERTIFIED" will be visible on the dial.
If you're looking for quartz precision at a more affordable price, then the battery-powered models are a good option. Even the chronograph versions of the PR 100 are powered by a special watch battery. The quartz models cost under 500 euros, although the newer mechanical watches with the Powermatic 80 caliber are more expensive. If you're prepared to spend more than 1,000 euros, then the simple versions of the Calibre 5
from TAG Heuer are good options. In the quartz watch sector, the Japanese manufacturers Citizen
offer many models similar to the PR 100.
The Powermatic's 80-Hour Power Reserve
Some PR 100 models are powered by the Powermatic 80 caliber, a mechanical movement that caused quite a stir at its introduction in 2013 at the Baselworld watch show. The 80 in its name isn't just a random number; it stands for the number of hours the movement runs before it needs to be wound again, either manually with the crown or through natural hand movements. Eighty hours is unusually long for a power reserve, seeing as normal automatic watches need to be rewound after 40 or 50 hours. You can put your Powermatic 80 aside on Friday and put it on again on Monday without a problem. If you only want to wear the watch on weekdays in the office, then this long power reserve is a practical feature.
The movement is the result of a collaboration with ETA, the largest ébauche manufacturer worldwide. It's based off of a popular caliber, the ETA 2824, which was first introduced in the 1970s. This new, improved version with a longer power reserve, the Powermatic 80, is also known as C07.111.
More Tension, Less Friction
To keep the movement's power consumption as low as possible, ETA reduced the balance wheel's frequency from 28,800 alternations per hour (A/h) to 21,600 A/h, equal to a reduction from 4 to 3 Hz. The number of jewel bearings was also reduced from 25 to 23. In return, the developers created more space inside the barrel so that the winding rotor could be put under more tension. Furthermore, the Powermatic 80 uses some parts which produce much less friction than normal. Thanks to this reduction in friction, the watch can run for longer. The Powermatic 80's winding rotor is engraved with the brand name and founding year: TISSOT 1853.
The C07.111 caliber can also be found in a slightly modified version in watches from Hamilton
. ETA produces two versions of the caliber for Tissot, COSC certified and non-COSC certified. If the movement is certified, then the average deviation per day is no more than two seconds. Certified watches cost a bit more than the regular Powermatic 80 versions.
- Powermatic 80 caliber runs for 80 hours
- Some versions available as certified chronometers
- Chronograph measures 1/10ths of a second
- Date display at 5 or 6 o'clock
Certified Quartz Movements
The Powermatic 80 is without a doubt the most technically interesting movement available in any of the Tissot PR 100 models. It is joined by many quartz movements which are ideal for those who enjoy their practicality. One such movement is the G10.211, which powers the chronograph versions of the PR 100. The large second hand times up to 60 seconds, and then the 30-minute counter subdial at two o'clock comes into play. As the name suggests, it can time periods up to a maximum of 30 minutes. You can measure time extremely precisely with this watch; the subdial at two o'clock measures 1/10ths of a second. The actual second hand is located on a third subdial at six o'clock, and the date display window is a bit to the right from the five o'clock position.
The caliber 955.112, called Normflatline by ETA, powers some versions of the PR 100. It is 2.5 mm thick and with a battery lasting between 78 and 108 months, meaning it takes at least 6 years before you'll need to change the battery for the first time. The ETA F04.111 powers the women's models of the PR 100 as well as the 39-mm men's versions. The F04.111 and the F06.111 both appeal to fans of accuracy, as Tissot offers the movements as COSC-certified calibers. A watch passing the COSC test standards deviates a maximum of seven hundredths of a second per day.
